CCNP ENCOR Lab 1 - Implement Inter-VLAN Routing

two rows connected with a serial link into two layer three switches and then we have an ipv4 and ipv6 topology and i've got myself set up in netlab here got my r1 mr3 and we've got a couple of isr four two two ones and some layer three switches as well so let's get started with the configuration let me just reappear all right okay so obviously um you know cabling and stuff we don't have to cable the the network because we are using the netlab to do this so let's um just start with the configuration we'll just go could copy and paste but let's just go for hostname would be r1 uh line con exact timeout zero zero logging synchronous and then we want a banner some reason when i press pound sign on my keyboard it gives me that um this is our one comma inter vlan uh routing vlan routing lab um and i believe we have a space at the start there okay and then we need to apply a similar config to our three so let's head over there and let's just enable this and let's do hostname r3 line con0 and i'm guessing we have a um i actually missed out a step i mean i missed out okay exact timeout zero zero logging synchronous and a little bit of the old banner ammo td let's kick yourself one too many there this is i'm gonna guess it's gonna say r3 e comma enter vlan routing lab and intel has a capital right oh of course we need banner motd there don't we otherwise that's not going to work this is our three interviewer okay um and the other thing we need to apply was uh no ip domain lookup no separate words yv domain lookup and we need to apply that let's just do righty on there and let's just apply an oip domain lookup over here and do righty and let's get on to the configuration of d1 let me zoom this in a wee bit so it's easier for me to read okay d1 so same thing on d1 let's enable conf t uh no ip domain lookup and also hostname and we're going to do d1 and then link on zero exact timeout and we want zero zero don't forget about logging synchronous exit and then let's just do the banner get a message of the day i guess it's going to say this is d1 yes this is d1 comma into our vlan routing lab space and maybe we can copy that to the text editor wouldn't that be fun just try and copy that to the browser and see what happens maybe i can paste it into d2 right and then let's just do an exit and uh do right here on there as well oh just a righty and d2 now and no ip domain lookup and we have a hostname and that'll be d2 line on zero exec timer zero zero logging asynchronous and exit and let's see if we can paste this panorama tdn wouldn't that be fun oh brilliant right okay so let's put this as d2 there of course i need to put banner more td before obviously right motz and then this weird thing that happens because i've got the uk keyboard puts a little b there something to do with it doesn't like british keyboards hates them okay this is d2 excellent um let's do right there okay set the clock on each device to utc time set the clock save the running convict oh okay right not done a clock set in a long time i think the last time i did it was on like i don't know it's like eight versions ago so i believe it's clock set unrecognized commander clock question mark um time zone actually mark word we'll just go for the utc always see what happens incomplete command i was offset from utc zero huh nice okay um so we've to do that on the mall apparently copy and let's do um okay so let's and then we've got to save running config startup config so do righty there and then over here let's do um t and let's do paste from the browser okay and let's do [Music] here and let's do here paste in let's do okay right configure and verify inter vlan uh routing on a layer three switch so in part two you'll configure and verify and in our vlan routing on the layer 3 switch and for this part focus on the configuration of d1 and r1 note the default switch database manager on the catalyst 350 supports dual stacked operations and requires no additional configuration okay so um let's configure d1 for inter vlan routing okay so d1 so let's go in here and let's do ip routing all right um an ipv6 unicast rowing my favorite kind and vlan 50 name we're gonna do name yeah name group 50 no space in there either and then exit and we're looking for a vlan 60 now vlan 60 name group 60 and exits okay now assign the gigabit zero slash 23 to vlan 50 and gigabit zero one to okay so this is this is where there might be some problems with the interfaces but what i'm gonna do is i'm going to do show ipnbr and just have a look at what we've got so the lab wants me to configure 1023 and we've got a 1 twenty three so we're not going to have a problem with this okay so interface gigabit uh one slash zero slash effect three we're in and we want switch port mode access switch for access vlan that would be 50 okay and no shot no shutdown and exit and then we want to configure um interface 24 i would guess yeah i know phase 24 with uh switch port mode access switch port access vlan 60 no shutty okay so bring those interfaces up now okay and then it wants me to create the svis okay that'll support vlan 15 vlan 60 so let's go into the actual svi uh so interface vlan 50 now and we want to do ip address um 10.2 2.50. one two and then we want an ipv6 address and we want something like f e 80 colon 2001 oh no colon cool on d1 colon2 right that's nice and easy to write out isn't it link local okay um and and then we want the actual ip address that'll be the one that i was thinking 2001 dba right just go on autopilot 2001 db8 is it a c a d yeah ac 1050 colon cool on d1 i do like how you can put the name of the device in the uh the ipv6 address that is that is quality um no shutter right and then we're going to go and configure interface vlan 60 now so interface vlan 60 and we want an ip address of 10 to 61. let's just change that in the third octet there and we want an ipv6 link local address of d1 3 there and we want on ipv6 address oh let's see i've got it in the i've got it in the history here somewhere of so dba acad 1060 d1 all right no shutting and exit you should see some interfaces coming up we'll see some see some action shortly so now configure pc1 with the addresses specified in the addressing table further assign default gateways of 10 to further assign what does it mean further assign like configure them and then further assign them just doesn't matter okay so it's just strange strange wording right so we're going where we're heading pc1 and we're getting the address table so there's the address table there's pc ones addressing there so let's go pc1 and let's get the oh look it knows it's in a network now yeah and let's do start and let's see we can get into the network open networking internet settings no change we want network and sharing center and we want change adapter settings and we're going to configure network here properties ipv4 okay use the following ip address so pc1 should be on 10 vmware's up 10 2 50 50. okay 10 to 50 50. and then you know what i'm going to do i'm going to copy that ipv6 address because i'll definitely mess up and put it in now is it saying that pc1 according to the diagram the gateway of pc1 should be uh the the 1023 interface on d1 so let's just okay so whoa first of all slash 24 right so let's do slash 24 we can do that easily and then the gateway should be the d1's primary network address this 10 to 51 that's the 110. oh and this is because we're in vlan 50 that makes sense doesn't it why is it not let me type the gateway in 10 2 51. okay let's do ipv6 now i've got it on the clipboard so it should just go in go on okay fair enough i'll type out 2001 db8 acad and then it's 10.50 and then it would be so we're looking at pc1 1050 colon colon 50 64. okay prefix will be 64. oh don't write the prefix in the address and the gateway right so the gateway is vlan 50 is this address here i'm just going to highlight the kind of difficult about that so it'll be 2001 dba um acad 10 50 colon gone d1 do we need the slash 64 in the gateway i don't think we do we might have to come back and add that invalid or no we do it right okay slash 64. try that invalid ip address 2001 got a dot in there i'm going to take away that um thing as well involved gateway i'll get there invalid gateway oh dba needs a call on there i don't think we need the prefix on there i really don't right cool okay let's go back down in the lab now and see what it says so uh configure pc1 with the address specified further assign the default gateways of those two things done now configure pc2 with the address and further verify all right okay so let's go and configure pc2 and we'll leave that on on the network and we'll leave that on change it up to sends there just in case we have to come back into it so pc2 and we have do you want to allow yes um let's go in here and then we want the network sharing center let's do ipv4 use the following so this will be 10. 10 and let's just get the ip address in from the ip addressing table up here so we're doing pc2 now 10 to 60 50 10 to 60 50 and it's a slash 24 0 and the gateway will be the address in vlan 10 to 61. let's do 10 to 61. okay and then let's do the ipv6 address where i'll probably make a lot of typos so ipv6 so let's just scan pc2 the kind of end bits the the bit that i usually mess up so 2001 colon dba go on acad colon 1060 colon colon 50 and then the prefix length is going to be 64. seems to have it seems to know that i don't know how didn't know the last time okay and then it's going to be this 1060 d1 so actually i can probably get away with just copying that pasting down there and then being like so instead of 1060 colon colon 50 it's 10 6 deco on d1 right let's just try that okay identifying it says it's connected to something right let's go back to part two and see how we're getting on here where are we um okay configure pc2 from pcs one from pc1 ping pc2's both ip addresses right let's go back to pc1 and let's get the command prompt open actually come on what year is it let's do let's power hell right ping and it's 10.2.60.1 i think it is ha didn't expect that to work right okay good um so i think i need to go to pc2 now and we'll get power as hell open and let's ping 10 dot what are we pinging 2.50.1 ha that's working right okay so according to the diagram right that's going up through pc1 into d1 and back out again um cool okay so now what we want to do is examine the mac address table on d1 with show mac address table dynamic okay i should probably ping the ipv6 addresses as well shouldn't i and let's just do an ip config on here and we'll grab the ipv6 address there oh come on don't tell me you can't copy you think with them bringing out a new shell did at least allow this at least at least let you copy right so let's ping that but change that to 10 50. reply okay nice okay let's go to d1 and the command it wants is show mac address table dynamic so let's go for a show mac address show mac address maybe we need to do this from privileged exact mode show mac address table oh all sorts of fun things right dynamic all right and we can see that like total mac addresses for this criterion two we can see that we have some mac addresses there right let's configure the gigabit zero one eleven in an interface is a rooted port um so on d1 let's do interface okay g1 i mean this is this is very much like what i see maybe maybe this is what i'm seeing maybe this is meant to be right i don't know let's just move on and let's do no switch port ip address 10.1.13.13 and then we want an ipv6 address of fe-80 d1 1 link local and an ipv6 address of 2001 d v 8 a c a d 10 d 1 colon column d 1 64. incomplete command ah typo in there there we go so let's do no shot and exit okay now verify that gigabit is no longer associated with the vlan database by doing show vlan brief so we'll do we'll even abbreviate it even more we'll do do sh vlan vr and then we'll pipe that into include um [Music] include g1 slash zero slash eleven hmm so okay so they're definitely not in it says configure that as a rooted port verify it's no longer associated with the vlan database well it's it's it's in the default vlan um there's nothing coming back so it's not okay so now we want to configure some default static routes okay so iproof and we're gonna do a quad zero and it's 10 1 13 1. and then we need an ipv6 root of slash zero via 2001 tba acad 10 z 1 1 1 incomplete command ipv6 root colon colon 1 2001 dba acd colon colon one okay cool so you may see an error message about something being resolved failing to resolve this will indicate that the switch said and app and got no reply we'll configure that next okay can't wait right building configuration so configure r1 now we're going to r1 um so configure a rooted port so we've got a red port and we've got default routes heading towards r1 now we need to go to r1 and configure r1 so let's go to r1 and let's see what we're going to do so um configure r1 so it supports unicast ring so ipv6 unicast routing and then we want to do interface uh gigabit zero slash zero slash one and then when an ip address of 10.1.13.1 and an ipv6 address of classic fe-80 colon colon one colon one this rolls off the tongue ipv6 address and this will be the 2001 db8 acad and we want 10 d1 here go on 1 64. okay let's just scan that for typos okay no shotty and exits okay right now we need to configure the serial interfaces so we're going to do the one link now the link across to r3 so let's go um interface serial okay serial zero slash one slash one zero one one okay ip address uh ten one three one uh okay and then we want an ipv6 address i have a fe8 cone one colon two link local and another ipv6 address of dba acad 13 colon colon 1 64. 10 13. okay we'll shut down uh no clock rate on the serial interface i think there'd be a clock right maybe the other end is going to be the dce um okay so configure routing on r1 configure static routes to the network supported by d1 and the default route for everything else to point at r3 so we're gonna point the default route okay so let's come over there and let's do ip route ip route 10 to 0 0 255 255 0 0 via 10.1.13.13. so basically it's saying that anything that's destined for 10 to anything anything send it to 10 1 send it to 10 1 13 13. that's the exit interface or the next hop the next hop so i'm just going to double check that because i really don't want to bugger that off if i do that wrong now right at least i'll start to troubleshoot for ages try to fix that right ipv6 works 2001 db8 ac 1050 64. and that's going to go out via 2001 dba acad 10 d1 d1 right let's just double check that because that's a long address so 2001 dba acd 1050 colon corn slash 64 via 10 dba acd 10d1 colon clone d1 looks good and then we've got a very similar thing again except we're just going to change that to the 6d network okay then we have a quad zero route i think i've got so it's ip ipro and then and that's via 10 1 3 3 okay and then the ipv6 right and that's going to be cool on colon 0 so the default root 2001 dba acad 10 13 3 okay just double check that sanity check that okay let's just close down this pop-up from brave right now from r1 ping pc2 with ipv4 and ipv6 addresses okay so if all's gone well if i go from r1 i should be able to ping pc2 which is on 10 to 60 58 24 ping 10.2. i'm kind of half and half of this is actually even going to work input oh of course i'm in there well i'm not going to work them in do ping ha 100 right okay right we're kicking with gas now so we can ping from r1 we can ping pc2 through d1 here um and what does it want me to do to ping the ipv6 address as well we better do that while we're at that so let's say exit ping and then let's do pva and then pc2s 1068 colon call on 50. so acd 10 60 corn corn 50 yes success rate is 80. so we lost one on the ark there but if i run it again we'll get 100 percent so that's is we're up in operation on ipv4 and ipv6 so um right okay so from r1 ping pc2 all things should be successful success right moving forward we're on to part three now part three configure and verify uh router based inter vlan routing okay so first of all we need to configure d2 to support the required vlans so let's head over to d2 for the first time in a while with this lovely orange color and let's do vlan 75 name group 75 that's it and we want vlan 85 name group 85 i'm gonna guess how imaginative okay and then we're gonna do vlan triple nine and name native vlan exit okay now we're going to assign the interfaces on d2 to vlan 75 and 85 so let's go interface gigabit ethernet and we want to go 1 0 23 and then we want to set that to be on an ip address no ip admission ip admission that's so strange it doesn't like ip so odd question mark oh interface vlan a sign wait assign the gigabit z g one zero ah right okay so i'm jumping ahead right okay so hang on so let's go interface gigabit ethernet um g one slash zero slash tracy i'm not gonna tell you how to do this it's just gonna assume you know now that it told you briefly back there and it doesn't like gigabit anymore for some reason hang on let's just try let's try again right okay interface gigabit ethernet one slash zero slash 23 okay switch port mode access switch for access vlan and says to vlan 75 okay and then we want to do interface gigabit 24 and we want to assign that to vlan [Music] 85 access vlan 85 okay then it says we want to create an svi that will operate in vlan 75 and it's kindly going to tell us how to do that thank you and let's just do a shot on that exit okay so interface vlan 75 ip address 10 3 75 14. oh 10 3 75 14 and then we're doing an ipv6 address of fe-80 colon con d2 colon colon one link local and then one on ipv6 address of 2001 db8 acad three oh seven five cool one calling d2 64. okay then we want a no shutdown on an exit okay no shot exit right so now what we're going to do is we're going to create an i triple e 802.1q based trunk to r3 so let's get into interface gigabit ethernet and we want the one slash zero slash eleven interface switch port mode trunk switch port trunk native vlan all the nines switch for trunk allowed and we want to send over 75 85 and triple nine no shot that's it so what we've done there is we've set up our trunk link on this gigabit 11. i'm just going to go and scan back to the to the to the diagram so interface 11. so that's this interface coming out of coming out of d2 just here it's quite difficult to see but basically this interface up coming out going up um to that device right okay so wing protocol change state to up okay so now that we've configured that we just need to go to r3 to configure r3 to support some inter vlan uh routing so let's go to r3 and let's do interface gigabit zero zero one okay switch port mode wait i'm looking at the switch config there right no shutdown center sent it switchboard exit right and then we want to do ah now we're going to use sub interfaces right so interface gigabit zero slash zero slash one dot seventy five so sub interface router on a stick encapsulation dot one queue 75 okay ip address and then we want the 10 375 one okay and then an ipv6 address fe-80 colon colon three colon two link local another ipv6 address of 2001 dba acad and then we want 3075 64. okay and then i know shut down on there exit and then let's bring up the other interface so let's go all the way back to interface gigabit 001.85 okay and ip address 385 one can right hold on configuring iep routing on a lan sub interface is only allowed if that sub is already configured as part of our 802.1080.1q or isl vlan well it is it is going to be that so was he not going to let me or is that just just reminding me that that that's going to be the case because we need to continue with the suburban configuring ip routing on a lan sub-interface is only allowed if that's already configured as part of an 802.1 queue or enter switch link via well it is going to be configured as part of that so stop it right ipv6 so the link local address is going to be 3.3 3 colon 3 and the real ip the full ipv6 address the unicast is going to be 2001 dba acd 307 3085 colon colon 1664. okay no shot exit okay then finally we need to do the sub interface for vlan 999 okay and then encapsulation oh that's what's happened that i didn't run the encapsulation command on that previous sub interface that'll be why i didn't like it encapsulation dot 1q85 maybe i should just punch those those ip addresses back in 85 bad mask that was fraught with errors that configuration there i'm glad i've gone through and punch these in again um let's just run the link the local addresses in as well so what we call link local is three three yeah that's good and three eight five colon cone one is good as well so no shutdown shut down on that right and then finally we need to look at interface gigabit ethernet 00999 and then we want an encapsulation on that dot one q triple mine and then we just want to know shut oh native and then no shut there okay so that's our three configured to support inter vlan rowing now we want to configure pc3 with the address in the addressing table and further assign the default gateways of the two interfaces here so let's just jump up to pc3 uh here and it's 10 3 75 50. so pc3 let's go and configure our change adapter settings properties properties use the following address okay so pc3 should be 10 3 75 50. and 24 mask so let's just put and the gateway of pc3 okay so pc3's gateway is going to be the g102 address okay and the g1023 address is vlan 75 so it's going to be 10 375.1 let's put 10. and the 75 one okay and then let's do the ipv6 address as well so we use the following ips 2001 dba acad and then for pc3 we're looking at 30 75 colon colon 50 and then 64 bits now the gateway is going to be the the vlan 75 address so basically the same but instead of so instead of 3075 colon cone 50 is 30 75 colon colon one so let's just grab that paste that in there and we'll just change that to colon colon one like that that should be good okay nice right we'll use the old terminal on this one just to mix it up a bit so oh it likes it it's joining network too okay so now it's saying that i have to configure pc4 with the ip addresses in the addressing table and further assigning default gateway so let's jump over to pc4 and let's go into the network and sharing center setup pc4 right let's just go back up to the topology table and grab use pc4 here so 10 385 550 okay and this is slash 24 and it will be 10 3 85 and whatever the vlan 85 is eighty-five one okay and then let's do the ipv6 address use the following one so i'm guessing let's just paste we still thought i might have that on the clipboard 2001 and then we're looking at the ipv so 2001 dba acd 3085 colon colon 50 30 85 colon corn 50 and then we want to do that but i'm guessing it's going to be 30 3085 colon colon one for the vlan 85 yes so that needs to change to a one and eight to five going over okay cool right back down to our right so where are we look there it is joining the network so from pc3 ping pc force ipv4 and ipv6 address so let's just get the command prompt up ipconfig so we're 10 385 50. so let's go to pc3 ping 10 385 always nervous when this happens come on all right that's working indicates r3 is performing in our vlan rowing all right and let's just ping the ipv6 address as well well let's just go to pc4 get the ipv6 so it's fe-80 so ac so 3085 colon colon 50 30 85 colon go on 50. so ping 2001 30 85 0.50 now right have i got that wrong do i need to provide the 2013 85 colon con 50. let's just go up and double check that we have the right configuration so we're pinging pc4 85 cone colon 50 let me just put the prefix on there no it doesn't like it so something wrong with ipv that with the ipv6 configuration something not right let's just go back to pc4 and double check this is acad 1085 colon calling 50 30 85 colon colon one let's ping the gateway and see if we can get to the get to the router first of all so let's try calling column one that's not working either so we're fine on ipv4 addressing but we're struggling on so 3085 colon con 50 isn't working but it's working on ipv6 so that's something on r3 um right so sub interface so let's just go back in and just just see we can get this sub interface to work so it's the no more yesterday okay so so wait we want let's just go back see if we can get this fixed so implementing our vlan ring d2 vd3 right so it's interface gigabit 0 0 1 dot okay encapsulation dot one q 85 and then we had i've even it's even up here like 10 3 85 1 which is working that's working fine it's the ipv6 config that's not working 2001 acd 3085 colon cone one see i've set up there 2001 dba acad 3085 colon con one is definitely running on that rear so let's go back to pc4 2001 dba acne 3085 colon cone 50 ping 2301 v db8 pcid thirty eight two five three eighty five colon cone one three eight five o'clock is not pinging so this can't even ping its own gateway which is indicative of some problem with the configuration let's have a look in here see what we've got because working on ipv4 2001 dba acad 3085 colon colon 50 co 2001 dba 2001 dba acad 3825 cotton cotton one and that's the right sign 2001 acad 2001 db8 acad 3085 corn corn 50 and that's 2001 dba acud 3085 colon golden one hmm that should be pinging 2001 dba acad 3085 colon con one should be replying okay so it's definitely something wrong on r3 because it says that it's on 2001 dba acad 3085 colon colon 1 on vlan 85 is there okay let's go to pc3 and see if that one's working um so pc3 should be able to ping uh there is 75 colon one and pc3 can't ping either it doesn't look like but it looks like ipv um what about this configure r3 to support ipv6 unicast rating what if it was just that okay and then if we were to just do funny if it was just this one command ipv6 ipv6 unicast running right now will these pings work because that would be in that would indicate that ha it's working now brilliant okay just one command out and that's so 3085 colon con one is the other interface and can we get all the way to 3085 colon colon 50 yes we can brilliant okay so just how to bring up unicast rooting knew there was something silly there right now configure static can configure the interface with the addresses specified in the addressing table so stack routing on r3 to enable end to end reachability okay so let's do interface serial zero slash one slash one okay ip address number one 10 1 b3 ipv6 address uh fv80 and then we're looking at colon column three colon one link local and then ipv6 address dba kcad and then we want 1013 colon con 3 64. okay no shutting on that exit and then let's just do an ip root of the quad zero nature at 2 10 1 3 1 dot 3.1 and then an ipv6 default root colon colon 0 to 2001 dba acad 1013 go on column one oh it helps if you put root doesn't it okay so on pc3 issue a ping to pc2 and this should be successful this indicates that the routing solution is working in both directions so from pc3 we're going to ping pc2 and if it works then we're getting right through through the through the one link to the other side so let's go and find pc2's ip address we'll do ipv4 first so ping 10.2.60.50 almost can't bear to look ha it lives excellent right so that shows we're getting from pc3 right up through the network up from this side of the network here up over that one link and back down into pc2 good so that means that we've done this properly we've set this up in the way that we want it to be set up so the next thing we want to do okay so from pc3 do to do configure that on r3 configure a stack default route that points through issue this indicates the rooting solution is working in both directions fantastic right so we've got the routing running through so now let's examine the cam and cisco express forwarding details so this is the this is the real um uh this is this is kind of the bit that we wanted to go to this was the bit that the chapter was about in the ccnv book so let's do let's go to r1 and let's just clear off the screen and let's do the magical bit show ip cisco express forwarding and it will not work no well all right okay so this is the compiled cisco express forwarding table so this tells the device what to do with a frame or packet based on the destination address so it says here right that um this table gives the device a quick answer and keeps the cpu from being directly involved for example packets going to 10 2 0 0 are quick resolved to 10 1 13 13 so let's have a look at that 10 2 0 0 right next hop out there gigabit interface so now let's have a look at the show adjacency now and interestingly we've got some drop we've got some receive we've got some attached so these these attached ones are the actual configured network addresses and these are the forwarding addresses okay and interestingly we've got this kind of default gateway here configured with that quad route there okay so the next thing we're going to look at is show adjacency so show adjacency and we can see um the neighbors of each interface okay so for example and we have this and we have this now expand this command to get some more information so we can do show adjacency and let's have a look there's all sorts of stuff in there there's all sorts there's literally lots of stuff let's do show adjacency detail okay detail right so you'll see that the router has pre-compiled the layer 2 headers and other details to allow it to package information quickly so what's actually happened we've got um layer 2 by offset link layer connection id end cap length 14 link layer type ip protocol interface show adjacency detail allows it to package the information across onto the network ip ipv6 serial encap length 4. it's fantastic so what this is what this is showing is that we've got this cisco express forwarding fast sending on the network okay as it says up here um basically show adjacency detail is showing us that we have um so these layer two destination addresses that are set up and allows the the router to package the information quickly without sending it up to the cpu okay um and this is it this is cisco express forwarding um and it says here the little last bit okay um that it says so all right okay that's just a little bit to help you with to find out how the router is configured look at the interfaces and how many interfaces it has there's no way to tell this is just in case you've got a different model or like if you're using the uh the 1900 or something which ones to use instead but just look in here um so show adjacency detail i wonder if there's any other show cef show cf features show cf forwarding information base entries that sounds quite good let's have a look in there forwarding information base 19 allocated ipv4 entries 13 okay what about the table show cef table let's have a look at this is there some format modifiers on that perhaps show cdf short cef table detail look at that getting all sorts of information there so i wonder so we've got we've seen the the forwarding information base we've seen the cef table please show cdf and see what else we've got in here what about show cef line card let's have a look at that show cef line card summary now table let's have a look at the table nothing in there let's have a look at show cef uh features i was thinking there wouldn't be anything in there because we're using the the show ceo features global global punt features spd [Applause] cef accounting let's have a look at that one sure cef accounting there we go wow okay show adjacency detail so on gigabit ethernet 001 we have an address 10 1 13 13 right the encapsulation length is 14 the layer 2 destination by offset and the link type after end cap is ipr so i think what that's telling us is that it has the it's got the packet already built let's just check what the lab exactly says you'll see the router has pre-compiled the layer 2 header details and other details to allow it to package the information correctly so the the router has set these up it's it's got these built into the cisco express forwarding fantastic brilliant i didn't think all that would work by the way so that's really good just having a look at um serial point to points as well scroll down have a look at these serial links too serial point to point point to point and the the thing that's that's really good about the cef that's fantastic about the cef is it is it stops the information having to go up to the cpu so we can we can forward this now i had a look in the line card configuration there and i know it's not i know i know we're not using the line cards for this maybe we should have a we look um see what other options there were there were seats so the cef information let's classify packets events features show cef event so we'll have a look at that show cef events cause all sorts in here brilliant forwarding information base ipv4 host mode transaction triggered and i mean another good thing about this cef as well is that we we you know we didn't have to configure it we didn't have to to set up it just worked with the with the vlans you know the layer two information it just worked and which is fantastic as well right okay so that's been a little um run through of the first lab lab one of the ccnp and that is configuring or implementing inter vlan routing uh on the network and that's set up you saw i got it working uh there was a couple of um a couple of heart and mouth moments uh with the pings not working because i didn't enable ipv six unicast routing one more proof of concept four we end so i should be able to ping from pc1 to pc4 so pc1 is 10 to 5050 pc4 is 10 385 50. so let's go to pc1 and let's do it from powershell ping 10 385 50. almost can't look yes it's working so that's pinging from pc one over the one link to pc four and that shows the proof of concept that we've got this this lab working here hang on i'll move myself back down to the corner so we can see it okay so cisco express forwarding uh demonstrated pc1 working r1 working r3 working d1 working let's have a look at the status everything's powered on everything's up and running let's have a look at the content there's a little bit of an error message it gives you here about when configuring ip addresses on pcs configure the address on the ethernet bridge interface not on the ethernet interface oh i'm gonna be in big trouble i'm gonna go actually back to these pcs then and turn off put them back onto dhcp before i break anything um i'm guessing i'm guessing cisco express i'm guessing the uh net labs got a way of fixing that but i'll make sure that i go and turn those back okay well if that was helpful for you um good luck with your with your labs or whatever and that's it
