MPLS Basics VRF Configuration MPLS VPN Part 1

properly I am going to have here I have 10.0.0.0 slash 30 but if you see your diagram it is different I am using simple small numbers here in every new diagram it is one ninety two dot one sixty dot 3.20 I don't want to use the big number so I made it a simple 10.0.0.0 slash 30 10.000 slash for 8/30 you know so and so so the IP address of this interface will be ten dot 0 dot 0 dot this is 2 and IP of this interface will be 10.0.0.0 and this is 6 and this is 9 and this is 10 and here it will be living and here it will be sorry here it will be 13 and here it will be 14 and similarly here 150 dot one dot 31 at 128 129 130 similarly 129 130 OSPF is running on all these routers now as far now we have not gone to VPN stuff for VRS so just we are going to understand the MPLS behavior once again like yesterday and then from then we are going to start now MPLS is not enabled on any of this router so if I if I see I am seeing the route of r6 sorry let me go to one second here what I'll do I'll advertise a network interface Lubeck 7 in the interface Newburg 7 I have 7.7 dot 7.7 so I will say IP ospf one area 0 I'm advertising the Seven Network from r7 I want to see that on our 6 r6 is in some other direction some other end our 7 is in the other it I'm go to our 6 and going to say show IP route 7.7 dot 7.7 707 somebody to say it says I know how to go to 7.7 dot 737 through OSPF I have learned it my next hop is this louder means our 6 knows about 7 so if I think from here 7.7 dot seven is going to ping route is there but it is not MPLS shooting it's not label switching it is just how to easy traceroute 7.7 at 7.7 it's it's not having any labels here normal IP routing not multi-protocol label switching now we are going to enable MPLS on r1 from R 1 to R 0 or 5 we're going to enable impale is only on this so this is going to be a kind of ISP no one at anima system and these two are like you know customers customer r6 as a branch office r7 connected to other end of the ISP now I'm going to enable MLM pls why should we go for MPLS can someone give some to three valid reason why MPLS is needed so fast convergence because you do label switching in 2.5 layer correct another reason right so because you overlay every router on the path need not to learn all the routes what's are the customer need that is VPN concept will go to that one later to hide the customer they do again you know we go for MPLS that is also VPN all right so far security ooh singly alright let us go on anyway MPLS on r1 r2 r3 r4 and r5 even from r1 I would like to show you the trace of trace route 7.7 dot 7.7 with the source of one that one denoted one every router has a loopback interface with his own name r1 means 100 one or two means to left order to Detroit has look at interfaces right now I'm going to pin so this is the traceroute is happening without an MPLS now enabling MPLS is very simple what is it command just that's all in the global configuration mode you type in pls IP this enables are out there to be any less our router label switch router but on the interfaces MPLS is not really running the rubber trees enabled as an ELISA now go under and faster than the 2/0 2/0 I am NOT going under serial seal is connected to customer r1 is the provider edge r6 is a customer edge r1 is a provider edge here are five is a provider edge whereas R 2 R 3 R 4 our provider only routers because they're not concerned connected to any customer now on our phone on faster 3 to 0 because it is providers interface providers land I enable MPLS MPLS IP MPLS is enabled only this much enabling in pillars there is no many commands only your single command MPLS IP MPLS is enabled now what is the verification command someone tell me the verification command I want to check whether MPLS is running on fast ethernet 2/0 show MPLS i want to check whether MPLS is running on fast ethernet 2/0 for every LS interfaces that said it shows MPLS is running on this interface it's only on this interface we run and what is the default label distribution protocol it is LDP we don't have TDP by default how to change from LDPE let me quickly show you that also interface fastethernet 2/0 and then we say MPLS MPLS label protocol see LDP TDP or both TDP is old Cisco proprietary which users you TCP seven one one in study we saw that LG uses what TCP 646 TCP 646 is LDP TDB seven one one now if you want to use TB you can use TDP I'm saying TDP the protocol is TDP see the default one it is LD P if you say both your interface can talk to TDP as well as LDP right now I have said TDP let us take the same command up show MPLS LDP now you see in the bracket it says TDP is running have the distribution protocol label distribution protocol right now impedance is running on r1 let us go to our two and enable MPLS on our two MPLS IP interface faceted 1/0 MPLS IP interface fastethernet 1/1 MPLS IP when they form neighbor r1 or not to with a firm neighbor they won't why one side it is talking as LDP sorry TDP r1 is talking as TDP r2 is LDP by default so we need to match let us match interface faceted 1/0 what is the command to change the protocol MPLS label protocol I'll say both here alright now this should form neighbor see it is forming neighbor with a loopback interface of our word I was telling you like OSPF MPLS also picks a router ID that will be a Lubeck address and it should be a reachable address way important lot of the time you know we will form neighbor but but no updates no scene happens the problem you know you are not reaching the neighbor address if never address is not reached he won't have proper same between the routers so you will find you know MPLS speaking a router ID everything will be going good but they won't form neighbor they won't sink the problem is this neighbor address that it is chosen as a router ID is not reachable all right so that's why I always pay off on all the Dewback interface and this is a reachable addressing OSPF that router idea of neighbor need not to be a reachable address in MPLS it should be a reachable address right right a toy that okay next on there on down to three MPLS IP interface faceted 1/0 MPLS IP interface faster than 1/1 MPLS IP now I have enable to happiness MPLS asphalt neighbor first the comment is check MPLS neighbor show pls MVP neighbor see it says I got one neighbor you there's one more command on free ok then how much mental break that out is this I have enabled ldpr TDP I enable TDP but when it up show MPLS LDP neighbor how QB neighbor will be seen all right that's a good question but you know Cisco is designed in such a way that if you type LD been able to show TDP neighbor also right I will show you that I go to our r2 and say show MPLS LDP a neighbor you see you also see TDP neighbor c7 one one is what TD be right TDP r1 is TDP neighbor seven odd number whereas r2 or the sorry r3 r3 is an LD P neighbor that's why 646 port number so to see both LD P and DDP neighbor the command is the same command is same there is no separate comment for TDP right where we left I think we were in our for now r3 is done in lippy neighbor is only one neighbor let's finish on our for MPLS IP interface fastethernet one / zero pls IP interface fastethernet 1/1 MPLS IP alright similarly on our five only one interface interface fasted reduced at zero MPLS IP globally also MPLS typing and now MPLS is enabled on all these all these routers what is the proof what is the proof when I ping from a when a traceroute from r1 when a trace route for am r1 I could see labels in the bracket but you see all labels are saying every router uses the same label to go to 7.7 dot 7.7 no need to get shocked why labels are locally significant labels are locally significant to the router so 2 router can have same label number for that same network not a problem but if you want to have different label you restart the MPLS process so you will get different labels once the label is converged you see one once the label is assigned by a router it tells the neighbor that I am using this particular label once the label sharing happened you router that is coming inside will not use the same label number so if you would like to have different label I can go two or three I'm going to or three and I can change that by saying no MPLS IP I just cancel once I put the MPLS back to refresh my label number just to refresh my label number but you need not to have different label number even if the label numbers are saying there is no problem why labels are locally significant similarly let me also do some refresh on r5 no MPLS IP MPLS IP now you see I am going to trace the route from r1 you will get different different labels now because we refresh the MPLS process you got different different labels alright still if you want different label then you can go to our five once again I can say no MPLS Ikey MPLS IP now you will get different different label again 20:29 2013 go now how ambulance words our five is the owner of 7.7 dot 7.7 a sir no yes alpha is the one who pushes the label who is the owner of Empire MPLS cloud for our 7.7 that sound actually seven is all doubter 77.72 at 7.7 say show IP interface brief cellular 7 at 7.7 is on 12 to 7 but only an hour fault is coming inside MPLS domain know what our 5 will tell to our 4 is like this you see I'll go to our 4 and show you the routing table of or the data playing table data plane of MPLS MPLS forwarding this is the data plane of MPLS it says 47.7 dot 7.7 47.7 and 7.7 the local label is 20 and r5 is using label number 38 now let's go to our five show MPLS forwarding show MPLS LDP forwarding camacho umbrellas forwarding forwarding it says 47.7 dot 7.7 I don't have any label and here PHP will not happen why owner of 7.7 that 7.7 is not about to fight instead of the scenario what you saw is are five of the owner of the network so PHP happened on our foot what is PHP when I'll commit how popping so n1 is one router will pop out the label here are five is not really the final destination is not the end router it may be in an MPLS cloud it may be the first router an impedance cloud but still it is not the final destination that's why you don't see popping happens on our for this understanding you should have but for final five at 5 at 5 or 4 box the label out why 5 for final favorite 4 at 5 alpha is the owner so PHP happens on or for itself iran or for it pops the label out this understanding you should have when PHP will happen when PHP cannot happen v dot v dot v dot v is now 2 5 so router for what it will do it will remove the label it will pop the label out are sent to our 5 so that are finding our to do two lookups label look up and look up it needs to do only route look up whereas 47.7 37.7 it puts a label and sense it is RFI the one which is going to do both the lookup and send the packet out without a label why a single 1/0 which is a point-to-point network so let's also trace from here are six see from are six also you are seeing the label but this is danger you see a customer sees a label and customer sees how many hops to reach my branch office out to seven how to suppress see customer are six is a customer now customers seeing the label customer is seeing the gateway router IP address on isp network which is not good customer is seeing ISPs land they can use for attack they can attack the isp very easily if they have these informations now how can i SP hide this by not allowing TTL to be decremented if you know if you're not allowing TTL to be decremented you can hide the hop counts now currently how many hops you have six hops you have now I am going to hide the isp network from customer MPLS will happen but provider providers network LAN deter cannot be seen by the customer how to do that who to our world MPLS IP TTL not to get em below that we propagate it here propagate TTL I need to say what know by default in propagate CTL I'm saying don't propagate it here in name by doing so I can hide my ISPs path information so I'm doing this on r1 r2 or s well no MPLS IP TTL sorry propagated here now MPLS IP propagate ETL now MPLS IP propagate ETL and also on r5 now MPLS IP probability all right Danna now if I will go to r6 r6 is what the customer customer are seeing all the service providers information but we don't want that so we gave no MPLS IP propagate ETL because of that customer isn't oh ok yes now one more router I need to do that see previously the number of hops or 6 now it is only 3 hub but still it reaches it reaches I missed in one of the router where is 1414 we come where to all 13 14 that will be in our fire but I think I are for what happened I did now let's do one more time r r6 how comes how come this cannot come like this it shows one of the hop in the middle which it should not do pushing the equator you doubt it will be pending so it is all the cooler because of the day they're not that bad like routing protocol fast teacup every five seconds they send the hello messages they can sense it's fast like a gr PA can say we should be really of mycosis outpace but you ever what reason you will do it there is no reason why you need to do that there is no reason so like this this problem you know you can fix it somewhere some small town is happening but you understood then from six up we have gone down to three huh providers notorious healer all right so this is the command and what else we learnt yesterday what is the command to see the data plane of MPLS show MPLS forwarding what is the command to see the control plane of MPLS show MPLS LDP binding show MPLS and here it won't work we don't have emptiness on our six go to r2 and type show MPLS LDP binding so this command will show you the complete routing table of emptiness this routing determine of MPLS is built with the help of what l degree protocol label distribution protocol look at this it says for for forward for at footer for the local mobile is 18 and one of the neighbor one has a label number 18 another neighbor neighbor called 3.3 I'll take out three as label number 27 so neighbors label numbers are learned on this outer it is possible only through a protocol which is the protocol it is LDP the one which built this routing table of MPLS i call it as binding table now one more thing yesterday i forgot to show you that surf table will also have herbal now i want to show you then show show IP search 7.7 dot 7.7 255.255.255.0 will also have a label now that you can also find in the binding table for similar 207 at 7 local labels 20 it's the same thing okay sorry local number is 20 but to whom you will be sending it would be forwarding 7.7 at 7.7 packet 2 R 3 R 3 from RT you would be sending the packet to R 3 to go to 7.7 at 7.7 so the outgoing interface label is what you are finding in the chef's table that is one more good than the local label to push the packet you you know need your key label you need the next neighbors label so that's what founding the safe table so you know up to this level I think we finished and today what we are going to see is what if I have more customers connected to the same router same provider edge I have more customers you know here one here one you know on and here one let's assume like this all even numbers 6 8 and 10 belong to customer a all even belong to customer a but they are connected in different prior age all order nine eleven and seven customer be different size all right now if you're going to understand the next two hours of configuration I tell you CCIE you have cleared your create see see a lab in CCO lab the first portion of troubleshooting what people will feel free is emptiness and it is Sam like this what you are going to see now right so it's such an important thing so if I have more customer see a customer a SLS customer be connected to same site now if this router is going to have both the customers routing information in the same table there is more security between these customers repeating again if customers are out and customer B's route will be maintained in the same routing table of the provider customers I am giving says that's what be without customers beefs knowledge there is no security right so what we need is we need a virtual router to separate customer rate from customer B for that we go for we are F virtual ground again for already we are F for for each customer you need to have separate BRF if you don't know we are up then you need to provide separate separate router which is more costly right we need to go we need to we need to create some VXR virtual routing and forwarding so that a separate routing table will be mating for each customer and for each routing table there will be separate SEF table fare table separate routing table separate fab table for each customer is I'm starting the recording again as I told you before all even routers all evened out lives let us consider this customer a all our drawed routers let us consider as customer B so I need to to vrf I need to go to we are of here - we are of here for we have a customer a and customer B and here also - - and here for we are of B and here for vrf a customer so let us start from r2 by creating vrf we understand the purpose of vrf the one more one more reason why we need to go for Viera fence there may be two customers having same that work inside the inside the organization same they told inside their organization same network let's say now 172 not 16 this guy customer B also has customer a also as if they go to the same routing table then there will be a conflict you put them in two different different routing table no problem whether this customer is having 170 216 this one surrounds no problem still they will be maintained separate separately why for each route given by the customer there will be 64 bit off route distribution means added around this thing you should press network of the customer different shades let's say around distinguishes of customer is one core in one route distinguishes of customer B is one : b 1 : assign one current to one current to 1 : 1 1 72 16 that is coming from customer rail will be looking like this one sound each what about 16.0 dot 0 : 1 : 1 now coming from customer we look like this once not do at 60 got 0 times 0 : 1 : 2 are the same no one coin 1 here in the end here in the end on : - they're not the same what will be the size of the network address 32 + 64 96 64 bit of road distinguisher and drought target is being used now let us see about now distinguish and outer gate in configuration level and author I am going to create two VRS so we are if we are just give here a veer of customer now i pv f IP b RF and then the name IP d RF then a name let's say customer underscore a and then route distinguisher generally normally people will write the autonomous system in the beginning the means in the beginning as an out distinction let us say customer is in autonomous system 30 so they will say 30 and then they will put : and then they will say the IP address on the customer router let's say the IDS on the customer out there in our scenario is let us say a da got zero dot zero dot one eighty eight dot zero dot zero dot one this is how they will all right okay first IP address 88 0 dot 0 dot 1 : 30 the autonomous system number this is you know practically seen in the real world but we are not going to do this type of you know work not need it I am simply you know for for our and better understanding and simply say for customer a our destination will be 1 : 1 for customer B route distinction will be 1 : 2 so easy to remember if I put big big number it's not easy to understand the other concept so to make the concept learning easy I do this so in reality people will try to give an autonomous system number and some number or IP address of the customer and some and the autonomous system number or some number that's how they will do what is the size of this the size of this is 64-bit all right next round target we understood that yesterday router here why do we need now target it is the router target one makes a provider edge router whether to import or not they update that is coming via VPN when an update comes through a VPN it is now target the one which is going to define which is going to decide whether to import or export some subnets based on route target only customers customer is branch office can be identified right so we will talk about our target when we do practically I can show you so that you will understand better here I'm going to say for our target expert why do we need to export now all the network that is coming from our eight should be send it to our six and our 10 why they're all customer is router so you need to do what you need to take those routes that is coming from our eight and export it inside VPN so when you export the others will input so if you use X for exporting if you use 1 : 1 number inner the import they will use 1 : 1 see if I export here with 1 : 1 on our two on our when it will improve with on : 1 whatever you export the next phone number will be used for importing on the other side whatever you export in this side that same number will be used to import on the other side that's why I told you now target helps you to import whatever is necessary and filter others now so I'm going to say whatever that is coming in customer a vrf you export it with there is a number 1 : 1 and then whatever our six cents and whatever our 10 and our 6 cents you do what you import with any number if you say 11 code and 11 so make sure you export there with 11 : level but I would like to go with the same number so that we will avoid confusion so here here I'm for I am doing for export and import the same one code anyone nothing wrong so you won't be in confusion what - what number for export you want what number for import when you configure the other provider edge routers now we may customers in US v RF is configured let us do customer Beasley RF how to do what is the command to create v RF IP v RF any name customer underscore b and then you say now distinguisher is let's say 2 : 2 so 2 to go into i am using for customer be right there is no restriction of using this number alright so you can use it and then under what target router gate for both import and export we are going to use the same number correct for both import and export we are going to use the same number if that is the case you no need to say export import you no need to say that if for import and export it is the same number you no need to mention it you can simply say like this 2 : 2 means for both import and export it will be taken as 2 : 2 i want to show you that look at this sure run you see for customer B we didn't say export an input it takes automatically if you are going to use the same number for both import and export then no need to specify import and export separate separately you simply fire out target and then the number so this is what we configured now I what I'm going to do is I'm just going to copy this and paste it on there and outers it's going to be the same vrf configuration version against time now you know the commands right I am copying this and I'm going to paste it on r1 even though our one don't have a customer B I am just doing that it won't take you know extra process nothing now there is no customer connected to r3 it is provided only router so I'm not going to do any BRF configuration there if I do we are of configuration there it becames we are a flight which is out of chile's we can say I am NOT going to do any BRF configuration on r3 instead I am going to form VPN so let me go to r4 and paste it here alright similarly let me also do an r5 right step by step we are doing you know it's very easy so far what we have done or step is running on all this provider router and we have created vrf that's it next thing is when we create a wheel and what do you do just creating Union is not enough now you need to assign interface to ERF a same interface to Galen there veera membership likewise here we need to do vrf a sending interface to BRF now al good ours are Phi R one R one you see an R one interface serial 1/0 I need to put in v RF customer a because all even numbers we discussed like the customer a so what I'll do I'll go to interface serial 1/0 IP v RF forwarding for what we rf-4c you st underscore a this is v RF membership right it's like assigning a VLAN to an interface a semi interface to Avilan but the problem is I already have I have given an IP address on this interface I have already given an IP address on this interface and this was to synchronize was a member of the global routing table before now I am taking that interface from the global routing table and giving it as a separate routing table is that right that's what we have this for us it puts these intervals in a separate viewer of table that has a favorite of the print routing table when you do that what will happen your IP address will be deleted why you have been taken out from the global routing table see the moment I hit enter it says okay but I am removing your IP address from the interface why this network is no more belong to do every table this was a member of global Tauranga I'm before now I have plugged it from the global routing table and I have put it under we are a stable even OSB of everything that was running gone out it is like you know breaking down the broadcast domain in the in switch language you have broken down now put the IP address again correct correct you need to do everything BRF aware routing protocol vrf aware so and so everything should be we are at hamurana correct - fire fire - fire - - or 250 - all right I'll give an IP address let us check the routing table now I told you there will be more than one routing table now only one interface is a member of Vieira is there any comment for verifying brf's yes sure I Pete vrf you see there are two VR apps created called customer a underscore estimate underscore a and customer underscore B and they have web distinguisher 1 : 1 & 2 : 2 and it is serial once letter 0 a member of V RF customer a it's very important command very nice to troubleshoot if we have any problem with a MPLS VPN this is a very good place to troubleshoot whether to check C in C CIA exam this is also getting recorded I what I am saying CCI exam they won't ask you to do any sort of MPLS configuration from scratch if they will ask you to do you will do step by step very nicely as I am showing you and you will clear it very easily you need your troubleshoot what do they might have done instead of putting you see your 1/0 in the via of customer a they might have put ISPs interface fastethernet for that small reason you are not able to converge from one side to the other side you may be thinking about V GB issue you may be thinking about VL DP t DB but you will leave this one membership interface membership you know you got only two hours to solve eleven problems eleven tickets each the good may have more than one problem if you're not exactly saying only one problem will be there for one ticket two hours only I tell you only you are who you are you know what enough I am Marie other now puts you need to have very good hands on are as gone two hours only you making two hours only level problem no it's very very serious issue it's not that easy you will have about thirty thirty two routers thirty thirty two routers you need to have you need to think in all aspects and you will have eleven problems in that eleven tickets and each tier will have more than one trouble to be fixed to or will not be really sufficient unless you have a good answer so please no doubt these type of small small comment do not ignore these comments show IP vrf will show you all the view of creator and the interface that belong to vrf and it also see it shows you route distinguisher now where can I go and check out target it shows only route distribution I want to check whether what route target they have given here so that I can go to the other side and master out target and troubleshoot route target is again another place where they might have mismatched route target should match so then what is the command to see the router it show IP vrf a detail or brief brief detail detail it shows even the route target you see now target is to : tube for import and export to see the route target the command is we are of detail it will show you both route argot as well as now distinguisher alright now we have configured on r1 similarly on our two interface interface serial 2/0 on 2/1 interface serial 2/0 on 2/1 need to move put under vrf interface Celia to slur zero what is the command to assign an interface to a vrf IP v RF forwarding so I am saying you need to forward for him for v RF customer a similarly interface serial 2/1 IP d RF forwarding B these interfaces I have not assigned IP address so let me also assign IP address interfacing of 2/0 let us assign an IP address like this 150 dot same like what you have in the diagram 150 dot one dot 31.4 slash 30 so on down I will give 5 and top I'll give 6 so are 6 I'll give IP address 150 dot one dot 31.5 I matching you the diagram now 5.5 is on CDL to slash 0 to 5 5 are to 500 to 550 to all right similarly on interface serial 1/2 I won't I would like to give an IP address and here the IP address will look like this 32.0 32.0 now I'm just matching with the diagram that you have in your hand I'm going to be 115 or 1.30 2.1 on serial 2/1 interface serial 2/1 IP address this IP address is 150 150 dot one dot 32 dot1q point 5.2 500 250 - all right it is then now what is the verification commands for v RF q ib v RF ensures there are two brf's called customer and customer B with drought designation of one color one and two one two and the serial 2/0 is a member of the RFA and 2/1 is a member of fear of V now similar configuration I would like someone to come here and do an r5 and r6 I didn't order order to same like that here for customer be here for customer env right anyone anyone anyone in tears it's getting recorded yes welcomes it - ah hi he has already there nothing so also one is customer as I'm sorry what is this movie please read our only declare you treat it so odd number are the real customize tab you can see USD you like Khan state of Fiat 1.30 1.8 1.1 another region let's go to our family yeah if it be selected it will copy or we need to copy or sometimes you write so thank you so now we should see more than one routing table on each so do let us verify that I'll I'll show you an r1 first show IP route you see show IP route it shows only the global routing table now what do you need to do is show IP route star sorry show IP vrf show IP LFL out show IP route vrf come on this is the one all if you show you the global routing table plus the routing table of customer ID the routing table of customer B now customer B we don't have any customer B in our one provider edge that's why you don't find any network there we don't have any interface but customer a has an interface single one star zero that is sink surface and that that has a network of 150 at 1.30 one 150 dot 1.30 1.1 28 that is a network that is the network that we got so you have a separate routing table for this interface and all the other interfaces all the other interfaces that is not member of any vrf will be a part of global routing table so that is a fast internet 2/0 assumed under global routing table all those interface that is not a member of any BRF will be a part of global routing table so which would be used by ISP itself now let us also verify the same on our to show IP route BRF if you want to see only for customer a this is the command see you est underscore a only customer a routing table will be seen for customer be only customer be routing table will be seen but I'm not seeing any network may be the interface is shutdown interface serial 2/1 no shiny curve a serial 2/0 no shirt why something else is wrong show IP v RF is interface designed yes show IP interface brief serial 2/0 okay okay you know why i am not seeing the other side is not configured i am not say no shutdown on the other side so let us go nas or 8 or 8 I'll turn on all right as soon as r9 on our 8 interface serial once let 0 know start IP address is 150 dot one dot 31 dot of it's 6 according to the diagram to 50 or 200 to 500 250 to here boom at variable B error because this is custom don't assign this interface in any BRF similarly on our nine interface serial 1 slash 0 now shared IP address is 115 or 1 or 32 god - so we're out of error over 250 - all right now if I go back to r2 and check the routing table for customer a and customer B I'll find separate separate routing table you see here this is for customer B I got the route and for customer a also I got their out now pinging from here should be possible ping 150 dot 1.31 dot 31.6 says but this
