10.2.2.3 Packet Tracer - Troubleshooting Single Area OSPFv2

hi friends so welcome to all in this video we are going to see the packet tracer activity troubleshooting single area OSP of version 2 before that friends if you are watching my channel first time then you can subscribe this channel so that you will get a latest uploading video info directly into your Gmail coming back to our activity here we can see our a trussing table also we will go through the scenario here in this activity you will troubleshoot our ISP of routing issues using ping and show commands to identify errors in the network configurations then you will be documented errors you discover and to implement an appropriate solution finally you will verify NT 2n connectivity is restored here is the troubleshooting process use testing commands to discover connectivity problems in the network and to document the problem in the documentation table here we can see the documentation table and the use verification commands to discover the source of the problem and devise an appropriate solution to implement document the proposed solution in the documentation table implement each solution one at a time and to verify if the problem is or a solved indicate the re solution status in the documentation table if the problem is not resolved it may be necessary to first or remove the implemented solution before returning to step 2 once all identify the problems are resolved test for end-to-end connectivity yes so first of all what we will do we will check the IP address of each device also in this topology we will check with the entity visors coming to PC one here we can see the IEP at trust details so 1 7 2 . 16.2 1.2 it's correct Sarita mask and the default gateway coming to PC 2 we have to check a with or a crossing table here we can see the IEP across detail so 1 7 2 16 - row - sorry - mask and the default gateway it's correct and coming to PC 3 you can see the IP at truss your PC 3 192 dot 168 or to 1.2 to mask and the default gateway it's correct now we will come to each router coming to our one enable show running config and we will verify each interfaces and it's a truss here we can see Gigabit Ethernet 0/0 it's a truss 1 7 to 16 1.1 here we can see the details also to mask its correct then here we have a serial 0 / 0 / 0 here we can see the IP our trust 1 7 2 16 3.1 and to 252 it's correct coming to serial 0 / 0 / 1 192 dot 168 or 10.5 everything is correct coming to our to show running config G 0 / 0 here we can see that IP address 1 7 to 16 2.1 it's correct serial 0 / 0 / 0 1 7 to 16 3.2 and 2 to 5 - / 30 it's correct serial 0 / 0 / 1 192 dot 168 or 10.9 it's correct and serial 0 / 1 star 0 - not 9.16 5.20 0.225 yes it's correct also something to mask now we will come to our three nibble show running config coming to the G zero slash zero here we can see one 91602 1.1 here we can see the details yes it's correct serial 0 / 0 / 0 192.168 o 10.6 it's correct 0 0 / 0 / 1 10.10 it's correct now we are going to check OSPF configuration on each routers first of all we will come to r1 here we can see the details router OSPF 1 passive interface the Gigabit Ethernet 0 / 0 here we can see that interface it's correct also we can see in this topology free directly connected networks here we can see 1 that is 1 7 2.16 202 1.0 / 1 t4 we will check that in our router OSPF configuration here we can see that while they got a bit 0.0025 5 it's correct area 0 and coming to 172 dot on a 12 on 7 2.16 door 3.0 / 30 here we can see that 1 7 2.16 door 3.0 it's a door 3 that means it is large 30 yes it's correct and coming to thir network over here we can see 192.168.1.1 9 oh here we can see they given one seven two dots 16 third 10.4 so instead of a 192 door to 168 they're given here 1 7 2 dot 16 so we must change this network here piously here we can see the problem in this one it is not forming neighbor ship of it are three we can verify that coming to our one here we are going to give show IP ospf neighbor and we can see your only neighbor ID be how only one ID that is tender to door to door to we will check that router oh here I am going to be you enable show IP ospf for here we can see that heidi 10 door to door to door to so it's correct so we have to check with the artery show IP ospf and here we can see the ID 10.3 or 3 or 3 is a normal listed here now we will document the identify the problem so device is our one you will keep material can identify the problem here we can see this r1 is not forming neighbor ship with art free and to propose the solution here we can see we have to remove this network this time will copy this we have to remove this command and to be how to or replace this with this a truss that is 192.168.1.5 i will type that here 192 door two one six eight dot a 10.4 then we have to give a while take our two bits as 0 dot 0 dot 0 dot 3 and 2 area 0 now we will come to the implementation coming to r1 we will copy this command we have to remove this command configure terminal here we are to give a router we have OSPF and the process ID as one here we are going to remove whatever we copied we are going to remove that then we are going to add this network that is 192.168 or 10 dot for here 192 dot 168 toward 10.4 and the wild card with 0 dot 0 dot 0 dot through e area 0 just after giving this command here we can see process one neighbor 10th or 3 or 3 or 3 on serial 0 / 0 / 1 from loading to full loading done no we how to see do show IP ospf neighbor and here we can see neighbor ID we go to both neighbors tender to door to door - and 10 door 3.3 door 3 so here now our problem is all resolved yes previously we had seen we got only this neighbor ID 10 door to door to door - now this attend or 3 door 3.3 is also added that is its form the neighbor ship with r3 also well now we will come to the router r2 and - we will check the OSP of configuration here we can see that the router OSPF 1 and here we can see the network at trusts details also here they given the passive interface gigabit eternal 0/0 innovate it will be correct yes also we will see each networks here we can see that - 1 7 2.16 door-to-door 0/24 and the area 0 here we can see 1 7 to 16 2.0 it's correct and we can see the other all networks 1 7 2 dot 16 dot 3.0 yes here we can see that it's correct and we have a here we can see that Network it's correct also in the topology here we can see this router r2 is connecting to internet here we can see that interface serial 0 / 1 / 0 so we have here they set a default route here we can see that command hence obviously we have to give you the commanded default information originated in this router r2 for propagating the default or route to other routers r1 and r3 but we cannot see that command to default information originate in our show running config even we can verify this with the help of show IP route we will come to r1 and so here we will give the command show IP route and we will let Chuck the default route no we cannot see that yes so here we identified a problem on r2 so we will document that coming towards perche to documentation table device is r2 then identify the problem r2 is not propagating the default route and to propose the solution here you have to configure OSPF with the command default information spelling mistake I will change that in formation or jannat now we will come to the implementation coming to the router r2 enable configure terminal router ISP of process ID 1 courier to give a default information originate we can verify that the droid is propagated to this r1 and r3 or not coming to r1 we will check that show IP route here we can see that also we will check on r3 here we can see that now we will come to r3 here we are going to give the command show running config and we will verify OSPF configuration here here we can see the details and see interface so here we can see the network 192.168.1.0 here we can see that it's correct to the network 192.168.1.0 here we can see that network 10.4 also we have 10.8 everything is correct no we will give the command show IP ospf right we will see the neighbors here show IP ospf neighbor but here we can see neighbor ID we have only one that is 10.2 1.1.1 this is the ID of the router r1 and here we can see these are through is north foaming neighbor ship with this router r2 coming to our previous command to show running config here we can see in this interface serial 0 / 0 / 1 here they set IP ospf hello interval as 20 so here we can see this interface which goes to this router r2 here we can see that two serial 0 / 0 / 1 so for this interface serial 0 / 0 / 1 in this router r2 this hello interval also should be 2000 that whatever we set here on r2 should be the same on this router r3 for this interface so we will check that in this router r2 hurry we'll give the command show running config until we can verify that here we can see in the OSP of hello intro interval is not set so here the solution is either we how to set this hello interval 20 in this router r2 for the interface so serial 0 / 0 / 1 or we have to remove this IP ospf hello in traveler from this router r3 but in this packet is our activity for scoring purpose here we have to remove this IP ospf hello interval 20 from this router artery coming to our documentation table device is r3 identify the problem our true is not forming neighbor ship of it to r2 and to hear the proposal solution is we have to remove the hello interval command on the artery serial 0 / 0 / 1 interface o previous will now be resolved the soldier we will give a yes coming to the implementation and r3 configure terminal we have to go to that interface serial 0 / 0 / 1 & 2 here to give no IP ospf hello interval 20 here we can see a sometimes we get this message process one neighbor tender to door to door to own cereal to Rosslyn 0/1 from loading to full loading done yes so we can verify that to show IP ospf neighbor and to here we can see neighbor ID tender to door-to-door to also we will verify on the router r2 here also we can see that message process one neighbor tender three door 3.3 on serial 0 / 0 / 1 loading done so here we will give show IP ospf neighbor and here we can see that coming to our documentation table will resolve yes will resolved well that's all in this packet tracer activity and that is troubleshooting single area or SPF version 2 now here we can see our completion status hundred out of hundred friends if you have any doubt in this packet race or activity please comment below also if you liked my video give a thump also share the video to your friends and to finally don't forget to subscribe the channel if not at subscribed so that you will get latest uploading video info into your mail thank you
