16.3.1 Packet Tracer - Troubleshoot Static and Default Routes

hi friends welcome to war in this video we are going to solve this packet tracer activity troubleshoot static and default routes before coming to this activity friends if you like to get any ccna version 7 online classes or any project support or any technical support you can contact our team using our website link you will get from the description below and if you like to get this type of technical videos in future consider subscribing and also don't forget to enable that bell icon new to the subscribe button so that you will get notification message whenever we upload a new video coming back to this activity uh here we can see our addressing table uh devices interfaces and their ip addresses uh they specified ipv4 as well as ipv6 addresses here coming to the objectives in this activity we will troubleshoot static and default routes and repair any errors that you find troubleshoot ipv4 static routes troubleshoot ipv4 default routes troubleshoot ipv6 static routes then configure ipv4 static routes configure ipv6 default routes and configure ipv6 static roads so okay in this activity just we will troubleshoot just will identify the problems then we will let troubleshoot it coming to the background a newly hired network technician is attempting to pre-configure a simple topology that will be delivered to a customer the technician has not been able to establish connectivity between the three lands you have been asked to troubleshoot the topology and verify connectivity between the host on the three lands over ipv4 and ipv6 we will see the instructions step one allocate and document the problems or record your findings in a table like the one below so we have to find the problem then we have to write its solution that's fine we will identify the problems first here we will be having uh either a static or a default root problems uh in this network so just we will go through uh each router that is r1 r2 and r3 then we will check the configuration they have done first of all we will go to r1 enable let me verify show ip root and here we can see they configured this static default route via 172.31.1.195 so here they specified this uh next-default address we will verify this next hope address also let me check with ip show ipv6 root we can see they configure these static routes okay so we'll start with ipv4 coming to the topology here in this r1 they configured the default route uh towards this side uh i mean towards r2 and here they specify the next two hop address that is the ip address of this interface serial 0 0 0 in this router r2 so just i will go to r2 and here we can see its address 172.31.1.193 oh here we can see they configured incorrectly here they given the next two patras incorrectly 172 31 1.195 let me verify it here and addressing table we can see it should be 172.31.1.193 but they configured as 195. yes we identified the first problem in r1 we have seen this ipv4 default to root it's a next hope address they configured incorrectly we have to correct it so you can write that problem here okay and solution is obviously uh we have to remove that type default i mean default root and we have to add the default root with the character next to hope address right we will go back to r1 and here i will give show running config running config and we can copy that line whatever they configured incorrectly yeah it's here just i will copy this command because we have to remove it right then conf t then we will give no and then we will give that command i p root and then this next to our patrons now we have to correct it uh we have to remove this and now then ip root okay okay and here we have to change it to let me once more verify in this addressing table as 1.193 here i have to give 1.193 okay so we can verify it just exit show ip root now it's correct even we have to verify ipv6 also let me go here i will give again a show running config and here we can see they set these three ipv6 route with exit interface that's fine and here we can see exit interface they given you serial zero zero zero i think it's correct yeah serial zero zero zero it's correct so we have to see uh the network address ipv6 network address we'll keep it here and here we can see 2 0 0 1 db 8 3 4 5 okay it's easy to remember so here we can see land two two zero zero one dba to three double colon slash sixty four it's correct then here we have a four double colon slash sixty four this is also correct then here in land three we have two zero zero one dba to five double colon sixty four yeah it's correct there is no problem with ipv6 uh static route next we will go to this router r2 enable show ip root let me try this and here for this r2 uh has a two remote networks lan one and land two uh here we can see they configured two static routes 31 1 0 31 1 128 so here we can see land 1 and land 3. here we can see the given a network address and this uh prefix are perfect 17231 1.017231 1.128 slash 26. we have to verify this next hope address what they're given uh it's so for 1.0 they're given 1.198 1.0 means which is towards land one and obviously the next two address will be the ip address of this interface serial 0 0 0 in this router r1 coming to our addressing table we will verify its address r1 serial 0 0 0 here we can see it's 1.194 but here they given one dot 198 it's incorrect right yeah so we have to change this then coming to the second one this is correct we have to verify this uh next hope address and here we can see land three so here the next two operators will be the ip address of this interface uh serial 0 0 1 in this router r3 so r3 serial 0 0 1 here we can see it's 198 198 oh just the swap that given the address it should be 198 here and it should be 194 here actually they interrupt change the next two operations so we identified a problem in r2 also uh we will correct it first of all we have to remove this configuration then we will add it correctly we'll give a show running config so that we can copy and paste that command here we can see that okay so just i will copy the first command and then we will remove it no then paste that it's removed oh sorry we have to go to global configuration mode kind of t then no give that command again give no we will copy the second line here both they configure incorrectly means uh they she interchanged its next to her matters right now we will configure it correctly just i will copy this first line and here we can edit this 172.31.1.194 it should be 194. okay then for the second one it's 198. instead of 194 it's 198 okay that's fine we can verify it show ip root and we can see y 1.0 seven two thirty one one dot one ninety four it's correct the ap address of this interface series zero zero zero then via 1.128 why are 317 to 31.198 and the ip address of this interface serial 0 0 1 now it's correct ok also we will verify ipv6 show ipv6 root and here we can see those static routes they configured let me see this lan one ipv6 address 2001 colon gbh colon 1 double colon slash 64 then a lan 3 2 0 0 1 colon db 8 colon 5 double colon slash 64. again coming back to our output here we can see static root for lan 1 2 0 0 1 colon db 8 oh here we can see the given six it's not six it's a dbh so they configured incorrectly this network they're given incorrectly right two zero zero one colon db six it should be db8 colon one double colon uh slash 64. uh via uh this next hope address uh we will verify this next to hope address also the ipv6 address of this interface serial 0 0 0 in this router r1 here we can see that 194 okay i'll come back and i will verify it here we can see 2 0 0 1 db 8 colon 2 double colon 194 it's correct so we have to change this network address here okay next we will go to static root 2001 colon tb8 colon 5 double colon slash 64 is correct we have to verify its next four patches per day given uh the ip address of this interface serial 0 0 1 in this r3 r3 here we can see ipv6 address we will verify with this 2 0 0 1 db 8 colon 4 double colon 198 it's correct there is no problem with this so we have to uh reconfigure this static route so we identified ipv6 uh static road problem also in this router r2 so just i will give a show command again show running config and we identified the problem here db6 okay just i will copy this command we will remove it conf t no then paste that command here then we will correct it we will change this db6 to db8 ipv6 root db8 yeah it's correct this is a solution next we will go to this router r3 enable show ip root we can see three static route they configured with the exit interface this is also configured with exit interface and this is also configured with the exit interface coming to our topology here we can see uh three remote networks for this router r3 lan 2 lan 1 lan 2 then this you know serial link this one link first of all we will verify this lan 2 172 31 0 0 slash 24 with x interface serial 0 0 1 i will go to r3 0 0 172 31 0 0 here we can see 172.31.0.0 24. it's correct is directly connected to serial 001 yeah this is correct next remote network is 172.31 dot one dot 192 30 with exit interface serial 0 0 1 coming to r3 and uh here we can see 172.31.1.192 30 is directly connected to serial zero zero one yeah this is also correct then coming to this lan one 172.31.1.0 slash 25 with exit interface serial 001 1.0 1.0 yeah here we can see static root uh 172.31.1.0 it's correct and to slash 28. i think they given slash 25 yeah they configured incorrectly so we have to correct it here this uh prefix or this to mask they configure incorrectly we have to correct this is directly connected to serial 0 0 1 ok this is fine but we have to remove this static root and we have to correct it here i will give a show running config so that we can copy that uh command yeah here we can see iep root 17231 1.0 and here they given a 240 instead of uh slash 25 that is a 128 right yes so we have to correct it just i will copy this command because we have to remove it const we will give no then give that address i mean that command then we will correct it copy again and paste here then correct that submit to mask 255.255.255.128 because they given the prefix as a slash 25 right and surely one is missing okay let me verify it so i ip root and now we can see this 172 dot 31.1.0 slash 25 is directly connected to serial 01. see here we identified the problems and then we resolved it that time itself okay so we can fill all these problems here and also we can write the solution uh whatever we given here and even we are going through this step two also repair the problems configure the devices so that full connectivity exists between the host on the lens over ipv4 and ipv6 also the given endnote here your task is to establish connectivity using the existing static road design changing the types of static roads used will be a result in a loss of points okay that's fine because we have to identify the problem uh then we have to solve it coming back to r3 again so we done for ipv4 next we will verify ipv6 show ipv6 root and here we can see static roots and here we can see only two static root ipv6 static roots because the previously have shown uh r3 got three remote networks i mean unknown networks that is lan one lan two and this one link right so but in this ipv6 routing table we can see only two static rules that means one is missing we have to identify it also we have to uh check this configuration also these two static road configuration also we will verify this ipv6 static route uh first of all we'll verify this 2001 db8 2 double colon slash 64 via a serial 0 0 one okay uh this sexy interface is correct we have to verify this ipv6 address to double colon okay fine here we can see two double colon this one link okay that's fine it's correct also we can see two zero zero one column dbh colon three double colon slash 64. this is for land2 yeah this is also correct that means they did not configure lan1 i mean they did not configure this ipv6 static road for this uh lan one and here we can see it's ipv6 address two zero zero one column dbh colon one double colon slash sixty four using its exit interface serial zero zero one we will configure it so this is the problem we identified again in r3 here i will give a short running config ok and here we can see uh ipv6 root they configured now we have to configure i will copy this command i will copy this line because we have to change only this uh extent ipv6 root 2 0 0 1 colon gbh colon it's instead of 3 it's a 1 double colon slash 64. here we can see that one double colon it's not 64. yeah it's correct the next interface serial 0 1 then press enter we can verify it give exit show ipv6 root now we can see these three unknown networks added here r3 is aware of all these remote networks so just now we added this ipv6 static root 2001 colon gbh colon one double colon slash 64 via serial zero zero one we can test the connectivity uh let me try to add this symbol pdu yes so i will ascend from this pc one to pc2 we'll try once more from pc2 to this pc one okay it's successful so ipv4 is working we'll go to pc to this server once more we'll try from pc2 to the server it's successful from server to pc1 successful now we will ping using ipv6 address we'll go to pc2 and we'll copy its ipv6 address we can ping from pc1 perfect we will go to server then we will ping to pc2 using its ipv6 address perfect i will get the iep address of ipv6 address of this server then i will test from pc1 yeah it's working okay that's all in this activity that is a troubleshoot static and default routes here we can see our completion status it shows a hundred percent now dear friends uh if you have any doubt any suggestions regarding this pike tracer activity please comment below and you can contact our team for any technical support link you will get from the description below stay tuned and we will meet again with the next video thank you
