4.4.8 Packet Tracer - Troubleshoot Inter VLAN Routing

hi friends welcome to world in this video we are going to discuss CCNA version 7 packet tracer activity troubleshoot inter VLAN routing before coming to this activity first if you like to get any CCNA project support or CCNA online classes we can contact our team using our website link you will get from the description below and also if you like to get this type of technical videos in future considered subscribing also don't forget to enable that Bell icon near to the subscribe button so that you will get notification message whenever we upload a new video now coming back to our packet tracer activity so we can see our a dressing-table device our one PC one and PC three and we can see interface on our one sub interfaces that is G 0 / 1 dot 10 and 1.30 and we can see its IP address 7 to mask default gateway for these pcs pc1 & pc2 3 also we can see VLAN information Charice or objectives in part 1 locate network problems in part to implement the solution then verify network connectivity here we can see the scenario in this activity we will troubleshoot connectivity problems caused by improper configurations related to violence and inter VLAN routing coming to the instructions in part 1 locate the network problems examine the network and located a source of any connectivity issues so commands that you may find useful include show IP interface brief show interfaces g 0 / 1 dot 10 and g 0 / 1.30 also show interface trunk yes using all these show commands we will the troubleshoot this network test connectivity and they use the necessary show commands to verify e configurations verify that all configured settings match the requirements shown in that dressing table lists all of the Blum's and possible solutions in the documentation table okay we will let stack troubleshooting this network we will go to our addressing table and we will verify these PCs pc1 & pc2 so we'll go to PC one then we will go to desktop we can go to IEP configuration or we can go to command prompt and we can use this command ipconfig /all and we can verify IP address so here we can see or a trussing table ok pc 1 170 2.17 dot that turned out it's correct something to mask it's correct and here we can see it's a default to Gateway 172 daughter 17.10.2011 you will give the command ipconfig space slash all and we will verify the IP address ok as per our dressing table pc 3 IP address 1 7 2.17 dot 30 daughter Jen son to mask it's correct then default to gateway 1 7 to 17 here we can see they configured a default gateway incorrectly the default gateway should be 1 7 2.17 dot a 30.1 but here we can see they configured 1 7 2.17 dot 10.1 we will add document to this problem we will close it then we will go to our spreadsheet problem and solution we identified the first problem that is we see three default gateway is con good incorrectly so solution obviously be able to change this gateway change the default gateway from we will see that gateway so we can see that the incorrect default gateway actually we have to set to 30.1 okay so we have to change from this atrás - okay we will give two 30.1 right okay now we will verify this switch s1 and here we can see this PC one is connected to FA 0 / 11 and PC 3 is connected to EFS euros now r6 and we can see there VLAN a PC 1 is in VLAN 10 and PC 3 is in VLAN 30 and also here we can see this interface that is gigabit a third 0 / 1 which is connected to this router r1 2 the interface a g 0 / 1 so this interface I mean this D 0 / 1 in this switch S 1 should be a trunk it will verify all these configurations we will go to s1 CLI presenter enable configure terminal ok we have to give a show command so we will go back to privileged x ik mode by exit command press enter again here we will give a show VLAN brief and here we will verify VLANs so we can see this port if a 0 / 11 is a same - VLAN 10 that is faculty or staff and here we can see FS 0 / 6 is a saint - VLAN 30 that is guest / a default so we can see it's correct and also here we can see this interface G 0 / 1 is in the default VLAN 1 so as we mentioned early this interface G 0 / 1 should be a trunk port so here from this we can understand G 0 / 1 is not in training mode even we can verify that using this a show interface a trunk a match okay we will try that show interface trunk commands or Eve's trunk okay and we cannot see any trunk he will document these problem you will go to our spreadsheet - here we will give interface that is a G 0 / 1 on I think it's s 1 right on s 1 is configured as it's access instead of a trunk it should be a trunk ok so the solution is we have to configure are these interfaces trunk so we have to configure this G 0 / 1 interface I say trunk ok now we will go to this router r1 and if we will verify its sub interfaces that is G 0 / 1 dot 10 and G 0 / 1.30 okay we can do that we will click on it you go to CLI so before that together we can give will go to enable so we'll give show IP interface brief command so that we can see these interfaces terrace IP address all these information ok we'll verify it ceteris G 0 / 1 dot 10 1 7 to 17 10.2 1 so we can see it's correct then G 0 / 1.30 it's a 30 row to 1 it's correct okay now we will check it status you can see this G 0 / 1 dot 10 is a minister or its administratively down and to the center G 0 / 1.30 is up sure if you observe we can see this physical interface that is Giga be the third 0 / 1 it's Terrace up protocol also upper but here we can see this specific sub alpha phase C sit down that is G 0 / 1 dot 10 he sent me straight Tivoli down so we have to give you no shadow on command for this sub interface we will close this novel minimize it R 1 then we will go to our spreadsheet and we will give our third problem identified the problem is sub interface that is G 0 / 1 dot chain is that correct we can verify it yes so S sub interface G 0 / 1 dot 10 is that means trade Tivoli down so the solution is so we have to bring these sub interface up give no shutdown command for this servant rephrase that is G 0 / 1 dot 10 right no here actually we cannot see it's something to mask also we cannot see the encapsulation so we can verify that we will go to each sub interface and we can verify it here we can see that show commander show interface then specify that serve interface okay we will do that we will give show interface it's G 0 / 1 dot 10 okay so here we can see the details gigabit a tyrant 0 / 1 dot 10 is administratively down okay all D we seen that protocol also down okay and here we can see it's a Internet actress 170 2.17 dot 10.1 slash 24 it's correct also we have to verify its encapsulation dot1q here we can see that encapsulation dot1q that's well and yes it's a saint for VLAN ID 30 no it's not for VLAN ID 30 so we can see it's VLAN 10 10.0 network and ago we can see they configure this encapsulation 8 no to 1 Q VLAN ID incorrectly it should be a VLAN 10 okay we will verify the other interface it is sha interface G 0 / 1 dot it's static right and sure we can see its IP at first 30.1 and its prefix encapsulation 8 node 2.1 q virtual VLAN ID 10 oh here also it's a configured incorrectly just a swap which we can say they're just misconfigured or just a swap this encapsulation 1802 1 Q VLAN ID so we have to change that so we will go to our spreadsheet and we will document this problem so here the problem is suburbs or a sub interface VLAN assignments are swapped on R 1 for G 0 / 1 tour 10 and G 0 / 1 - 30 right so here what is the solution for this problem obviously we have to remove these dot1q encapsulation dot1q VLAN then we have to give the correct encapsulation dot1q then we have to re-enter the correct IP address information as per our addressee table okay here is the solutions first one is that we have to remove what is that okay here I will you remove incorrect encapsulation dot1q so this is what we have to do then next we have to give the correct encapsulation dot1q you can give array as say in correct encapsulation dot1q also we have to set its IP address I mean correct the IP address for these sub interfaces so here are remaining everything looks correct now we will go to party to implement the solutions implement your recommended solutions right we will implement these solutions so first one we can see pc3 default gateway is configured incorrectly we will get its default gateway it's a 30.2 one so we will go to PC three it will close this command prompt then we will go to IP configuration and here we can see it's a default gateway we will change it to we will change this at ten to thirty dot one okay oh here we can see our completion status now it shows 25 percentage okay so next is interface this 0/1 on s1 is configured as access instead of trunk so we have to configure this interface G 0/1 sa trunk port okay we can do that for that we will go to s 1 then B had to go to that interface that is G 0 / 1 click on s1 CLI then press Enter enable configure terminal we can give a country then we will go to that interface that is G 0 / 1 and here we will give a switch port more as a trunk then press enter and here we can see the message line protocol on interface G 0 / 1 gone down then it come up so we will verify this configuration we will end and press enter and here we will give a show we will give VLAN brief then coming to this output sure we cannot see that interface that that is G 0 / 1 in this default to VLAN or any other VLAN see it's a FA 0 / 24 then we have G 0 / 2 ok because now this interface G 0 / 1 is trunking ok we'll verify that show interface trunk and here we can see the details so the port is G 0 / 1 its Modi's own and we can see encapsulation 8 node - dot1q status it's a tracking and native VLAN is in a default native VLAN that is 1 and the variants allowed and active in management domain 1 10 and 30 now we can see completion status shows 50 percentage and we have 2 more problems that is sub-interface G 0 / 1 dot 10 he sent me straight to bleed down so we have to give a no-show down command for this sub interface ok we will go to G 0 / 1 CL I enable Kunti then we will go to that sub interface that is G 0 / 1 dot 10 alright then we will give no on command and presenter it's right okay presenter and we can see now this a sub-interface changed stay to up also we can see line protocol or interface g0 slash 1.10 change the state to up you will verify the configuration we will go back to our run presenter here he will give end press ENTER again press ENTER we will give a show IP interface brief and now we will verify this sub-interface g0 slash 1.10 we can see it status up protocol also up and here we can see now the completion sheriff shows 75 percentage now we will go to the final problem that is a sub interface VN assignment sir swap on r1 for this of interfaces G 0 / 1 dot 10 and to 1.30 so we have to remove that incorrect encapsulation then we have to reassign the correct encapsulation dot1q with VLAN ID then we have to correct the IP address for these sub interfaces ok we can do that ok we will do that configuration will go to R 1 so we have to go to those sub interfaces right so it's kunti first of all we will go to the interface G 0 / 1 dot 10 then we have to remove that encapsulation so no encapsulation he'll protection mark and we can see we have to give sorry dot1q then press enter so that it will remove again we will put a space and wheel protection mark CR that means press Enter ok now we will go to the other sub interface so it just will exit from this web interface go to the interface g0 slash 1.30 right here also we will remove this encapsulation dot1q okay now we will a set the correct and capsulation first of all reveal a set for this sub interface G 0 slash 1.30 because we are in we are in this interface now okay so we have to give a encapsulation dot1q space then we will try with a question mark we have to give the VLAN ID so here we have to give its for VLAN 30 right then we have to set the IP address because we can see this IP address obviously our remote we have to assign the IP address just I will copy from here then paste here with the sub to mask okay see our percentage is increased 86 percentage now we will go to our interface I'm in the sub interface before that we will exit from the sub interface then we will go to the sub interface G 0 / 1 - 10 right so here we will give a encapsulation dot1q space will put a question mark so it's a VLAN ID 10 then we will have set the IP address it's a 10.2 one will edit it then it's a sub to mask presenter end presenter now we have to verify this configuration right we will give a sure interface G 0 / 1 dot 10 and here we can see no encapsulation it not true dot1q we then I read 10 it's correct also we can try to give a show interface d0 / 1.30 and here we can see its VLAN ID is 30 it's correct and now we can see completion status shows hunter percentage and finally in part 3 verify network connectivity verify the PCs can ping each other and r1 if not continue to troubleshoot until the pings are successful okay we will try to ping to each other so we'll go to PC one you'll go to command prompt will give a ping to 170 2.17 dot 30.1 and here we can see we get the replies you know we either try to ping to a PC three I mean from pc1 to pc2 three you can press up arrow then we will give that truss 30 rotor 10 this is the IP address of this PC PC 3 and if you are waiting for the replies yes it's working previously we ping to the sub interface G 0 / 1.30 so now we can try to ping to the sub interface G 0 / 1 dot Chen it will work no doubt so you can use up arrow so that we'll get the previous commands and we can edit this IP address it's a 10.1 then press Enter it's working so friends in this video we discussed packet tracer activity troubleshoot inter VLAN routing now dear friends if you have any doubt any suggestions regarding this activity please comment below also if you liked our video give a thumb and share with all your friends and if you'd like to contact our team you can visit our website link you will get from the description below stay tuned and if we will meet again with the next video thank you
