7.3.2.9 Packet Tracer - Troubleshooting IPv4 and IPv6 Addressing

- sir welcome to all in this video we are going to see the packet tracer activity troubleshooting ipv4 and ipv6 addressing here is our objectives in part 1 we will troubleshoot first issue in party to troubleshoot second issue and in part 3 troubleshoot the third issue we will go through the scenario we are in a talk technician working for a company that has decided to migrate from ipv4 to ipv6 in the interim they must have support the protocols that we will stack three co-workers how call that the help list with the problems and how received a limited assistance the help desk has escalated the matter to you a level to support technician your job is to locate the source of the problems and implement appropriate solutions we will come to a part 1 troubleshoot the first issue a customer using PC one complaint said that she cannot access the dual stuck server dot PK a web page so verify a detailed helpdesk ticket the helpdesk collected the following information from the customer over the phone verify that it is correct we will go through this helpdesk ticket client identifier PC one issue unable to access the dual stack server dot PK a web page here are the detailed information does the computer have an IP address using IP config yes can the computer contact its gateway using pink yes can the computer contact the server using tray cert yes can the computer contact the server using nslookup No so escalate to level 2 support right coming to the topology here we can see that the system a PC one and this pc one is unable to connect to dual stack server dot PKA now we will come to a step to consider a probable causes for the failure note that tests that have been conducted if possible a discuss possible scenarios that would create to the situation with your fellow network technicians so run more tests if it helps visualize the problem simulation mode is available so as per the helpdesk ticket they verified your IP atures there is no problem with IP address it is communicating with the Gateway and also the computer contact the server using tracer also so obviously we have to check the DNS server a truss here we can see that 64 dot and ridore 21.1 we have to verify the DNS IP a truss here that here we can see DNS server and the address is a 64 dot 100 dot one dot 254 here we can see that DNS server address are given wrongly so we must change the DNS server address here right now we will come to a step 3 propose a solution to solve the problem make a list of things that could be changed to solve this problem start with the solution that is the most likely to work ok implement the plan that try the most likely solution from the list if it has already been tried move on to the next solution right so we identified the problem verify the solution resolve the problem repeat the tester from the help the sticker to did it solves the problem if the problem still exists so reverse the change if you are not sure it is correct and the time to step 4 right so under document the solution record the solution to the problem if you ever encounter the same problem again your nodes will be very valuable right so here the thing is that we must change the DNS atras the DNS server our trust in pc one coming to pc one here we have to change it according to our addressing table here it is 1.2 54 so we are going to change to 1.2 54 yes now we will come to a party to troubleshoot the second issue occurs Tomer using pc2 complains that he cannot access files or the dual stack server dot PKA at this actress a 2001 : DB 8 : CAF e : 1 double : 10 so verify a detail the helpdesk ticket the rep desk collected the following information from the customer over the phone verify that it is correct here we can see a helpdesk ticket client identifier is PC 2 and issue is unable to access the FTP service of this server and detailed information about the issues does the computer have an ipv6 address so using ipv6 conflict yes ok can the computer contact its gateway using pink yes can the computer contact the server using stray cert no right so if collide to level 2 support right we will let check it now here is our a PC 2 so he will check its IP address ipv6 config all and to here we can see the arches now we will Epping to our default gateway so we will give a pink fe80 double : 1 yes so there is no problem be able to ping to the Gateway now we will give the tray set command here trace hurt to the server right LLL give tray cert and ipv6 address of our server here we can see that here we can see the computer cannot contact the server using tracer now here we will verify the devel stacks server dot PKA coming to the server IP configuration here is our ipv6 configuration we will match with our acrossing table here we can see that mm 1 TB 8 CF e : 1 double : trends now 64 it's it's correct and here is a default gateway fe80 double : a here we can see they assigned the ipv6 a gateway wrongly on this a dual stack server so we must change this a default gateway step 2 complete step 2 to 5 from path 2 and for this problem document the solution record the solution to the problem if you ever encounter the same problem again you're not sir will be very valuable so we must change here ipv6 gateway in this dual stack server so it's fe80 double : yay now we will come to part 3 troubleshoot the third issue a customer using pc 3 complains that he cannot communicate with the pc to verify a detailed helpdesk ticket the help does collect the following information from the user over the phone verify that it is correct here the information helped us ticket fly a client identifier is pc 3 unable to communicate with the PC 2 so does the computer have an IP address using IP config yes does computer have an ipv6 address using ipv6 config yes can't a computer contact its ipv4 gateway using pink no you can the computer contact its ipv6 gateway using pink yes so can the computer contact the ipv4 client using tray cert no can the computer contact the ipv6 client using try cert yes so now we will check it your complete the step 2 to 5 from part 2 and for this problem document the solution or record the solution to the problem if you ever encounter the same problem again your notes will be very valuable we will come to pc3 command prompt - here we are going to give ipconfig/all and - here we can see this ipv4 address and subnet mask default gateway all these notes it but here they mentioned does the computer have an IP address using IP config yes so actually here is a mistake right so also the given can the computer contact its ipv4 gateway using pink so they mention didn't know because even here we can see in this router this network is connected to this interface a Gigabit Ethernet 0 / 2 so we have to check the IP address of that show IP show IP interface brief and here we can see that you gotta be 2/3 0 / 2 IP address is unassigned right we will cross-check the ipv6 address here so ipv6 config all and 2 here we can see the details right also we will let's check the I trust your show ipv6 interface brief and here we can see the actress theories the default gateway is Fe 8 0 w : 1 we will dip into the default gateway pink fe80 double : 1 we are getting a replay we can see this a PC 3e say ipv6 client and we can ping to this dual stack trine 2 here we can see they are using IP configuration they are using both ipv4 and ipv6 we will try to ping to this ipv6 command prompt here we will Epping right yes we are getting a reply also here we can see in a PC - in IP configuration ipv4 here we can see they given IP address subnet mask but they did not specify the default gateway here so we have to uh say in this a default gateway here here we are going to give the default gateway it's one ninety two dot one sixty eight dot zero dot one this patter three troubleshooting is obviously there is an ambiguity because here we can see this a PC three is ipv6 climb so PC two we can pink I mean from PC three to PC - we can ping K using ipv6 address of a PC - and once we said this ipv4 default gateway we will get the completion status 100 out of 100 anyway here this a packet resolved activity you say simple troubleshooting activity of ipv4 and ipv6 addressing friends if you have any doubt comment below also subscribe the channel so that you will get latest uploading video info into your
