17.7.7 Packet Tracer - Troubleshoot Connectivity Issues

hi friends welcome to all in this video we are going to discuss is the innovation seven packet racer activity troubleshoot connectivity issues before coming with this activity friends if you are watching our channel first time or if you like to get this type of technical videos in future considered subscribing also don't forget to enable that Bell icon unable to the subscribe button so that you will get notification message whenever we upload a new video and also if you like to get a more technical contents or if you like to contact our team you can visit our website link you will get from our Facebook page go back to our packet tracer activity here we can see our addressing table with device its interface its IP address subnet mask and it's a default gateway now coming to the objectives in this packet tracer activity we will troubleshoot and resolve connectivity issues if possible otherwise the issues that should be clearly documented so they can be escalated now coming to the background you see some reporting that they cannot access the web server www.pmtasetup.com dns server you must determine the course and attempt to resolve the issues for the users clearly document the issues and any solutions you do not have access to the devices in the cloud or the server at www.fixez.com isesamo coming to our topology here we can see our users pc - 0 1 0 - then pc - a and pc - beep now they unable to access this website www.assist.org sure they given a note now turn our one can only be accessed using SSH with the username admin 0 1 and password Cisco 1 2 3 4 5 router r2 is in the ISP cloud and it is not access built by you yes sir here we can see our router r1 and we can access this r1 using SSH here they given the username and password for that and also we have a router r2 which is inside this is P and we cannot access this is P here now we will go to instructions in step one determine connectivity issues from PC - 0 1 coming to a topology here we can see our device PC - 0 1 so we are going to verify the details in this PC - 0 1 on PC - 0 1 open the command prompt then enter the command ipconfig to verify what IP address and default gateway have been assigned to PC - 0 1 correct as necessary according to the hydro sink table now we will go to this PC - 0 1 then a desktop command prompt and here we will give I P config then we will verify its IP address with our addressing table then we can see its IP address configured its 172.16.0.0 an addressing table PC - 0 1 here we can see its address 1 7 2.16 dot but here they configured incorrectly they given 168 so we have to reconfigure this IP address we will verify it sir - mask it's correct then it's a default gateway 1 7 to 16 1.1 it's correct now we will come back to this IP address we will close this command prompt then we will go to IP configuration and here we can see IP address we will edit this IP address we will correct you - one seven two dots 1600 - 1.3 now after verifying or correcting the IEP addressing issues on PC - zero 1 issue pings - the default gateway webserver and at our pcs wear the pink successful or record the results sure we can see we have a to ping to the default gateway then to the web server then we have to ping to PC - 0 - PC - a and PC - B so firstly we will Epping - it's a default the Gateway that is 170 2.16 dot 1.1 so coming to PC - 0 1 command prompt we can copy this IP address from here ping - it's a default gateway so here we get the replies now we will a ping to our web server here is the IP address we will copy that coming to PC - 0 1 will ping to our web server and we are waiting for the replies yes it's working now we will ping to our other pieces so we'll go to or a dressing-table and ashore you will get the IP address of a PC - 0 - we will ping to PC - 0 - we get the replies now we will a ping to PC - a and here we can see it shows a destination house to unreachable so we unable to ping - PC - a now we will try to ping Torah PC - B we will copy its IP address ping to PC - B and here also we can see we get the and replay as a destination house - unreachable so here we able to ping to its default gateway to our web server then to our PC - 0 - but it's failed to PC - a and to PC - B now use the web browser to access the web server on PC - 0 1 access the web server by first entering the URL HTTP colon double slash www dot Cisco dot PKA we will copy this URL and then by using the IP address a 2-0 9.16 5.20 1.2 then record the results he will go to PC - 0 1 then we will select this of a browser and coming to a URL ok then go and we are waiting for the webpage yes be able to access our webpage using this URL now we will close this and we will try with our IP address IP address of our web server we will copy this IP address then coming to our web browser again will paste that IP address in this URL field then press GO it's working right document the issues and provide the solutions connect the issues if possible yes we already see in the issue actually they even configured the IP address incorrectly and then we corrected that IP address in this PC - 0 1 ok now we will move it to a step to determine connectivity issues from PC - 0 2 on PC - 0 - open the command prompt enter the command ipconfig to verify the configuration for the IP address and default gateway correct as unnecessary yes we can do that we will go to PC - 0 to desktop command prompt sure we will give the command ipconfig and we will verify its IP address something to mask and default the Gateway you will check with our addressing table sure we can see it ceteris 1 7 2.16 . a 1.4 it's correct then here we can see it's sir - mask it's correct no coming - it's a default gateway sure we can see this default gateway is configured incorrectly it's 1 7 2.16 dot o 1.1 okay we will character is a default gateway issue now itself we will close this command prompt we will go to IP config and here we can see IP address subnet mask default gateway they configured incorrectly 170 2.16 dot one dot 11 it's not 1.11 it's 1.1 after verifying or correcting the IP addressing issues on pc - zero to issue pings to the default gateway webserver and other places where the pings successful record the results so we have to pink to its default gateway then to the web server then we have to ping to PC - 0-1 PC - a and PC - B okay we will do that we will copy it's a default gateway IP address then coming to PC - a zero - we will go to command prompt we will have ping - it's a default gateway from PC - zero - and here we can see it's working now we will ping to our web server we will copy its IP address being to web server it's working now we will a ping to our PC PC - 0 1 so we will press up arrow it's 1 7 2.16 dot 1.3 under here we can see it's working now we will ping to PC - a and the PC - B you will get its IP address PC - a it's a 2.3 ping to PC - a and here we can see we get a destination host unreachable now we will try to PC - B it's a 2.4 we can press up arrow and it's a 2.4 destination host unreachable so here or ping is succeeded to its default the Gateway then to this web server then to this PC - 0 1 but it's failed to PC - a and PC - B now a navigate to www.assist.org PC - 0 - record the results then we have these questions can PC - 0 to access www.score.org IP address these two we will verify now first of all we will try with this URL we will copy it then coming to PC - 0 - we will go to desktop then the browser and we will paste this URL in this URL field then go yes we can access this web page now we will try with the IP address we will copy from our addressing table it's here you will copy this now we will close this of a browser and the we will reopen it and we will paste that IP address in this you are URL field yes I be able to access this web page document the issues and provide the solutions correct the issues if possible yes we already done that sure in this PC - 0 - they configured the default gateway incorrectly we corrected the problem no we will go to step 3 determine connectivity issues from PC - a1 PC - eh open the command prompt then enter the command ipconfig to verify the configuration for the IP address and the default gateway correct as necessary okay coming to PC - a we will go to desktop command prompt here we will give I P config and we will verify its IP address we will go to our addressing table and here we can see PC - a its IP address 1 7 2.16 dot 2.3 it's correct and here we can see it's a subjective mask it's correct and coming to the default to gateway 1 7 2 dot 16 door to door to 1 everything correct after correcting the IP addressing issues on PC - a you choose the pings to the webserver default gateway and other pcs where the pings successful record the results so we have it to ping to this web server or default gateway then other pcs PC - be PC - 0 1 and PC - 0 - now we will go to our addressing table and we will copy our web server IP address and we will ping from this PC - a ping to our web server and we are waiting for the replies request timed out no it's not working we can see packet sent for but received a zero lost for 100 percentage loss now we will try to ping to our a PC - be sure we can see its IP address sure we can see it's working now we will ping to a PC - a zero one a request timed out no it's not working next we will Epping to a PC - a zero - it's a 1.4 request timed out no it's not working - PC - zero - also sure the pings succeeded only - it's a local network that is a to this PC PC - B and all other pings - the web server to the default gateway then to these pcs PC - zero one and PC - zero - is not succeeded then mostly the problem with this default gateway the IP address of this interface Giga be the third 0/1 in this our r1 no navigate to www.assist.org be seein a record the results so Ken PC - a accessories URL then using the web server IP address okay we will verify that now we will check that we will copy this URL then coming to our PC - a will close this command prompt then we will go to web browser and we will paste that URL this URL field and we are waiting for the webpage no here we can see we are unable to access this webpage hostname unresolved now we will a try with the IP address here we can see the IP address will copy that we will close this browser and we will already open it paste that IP address here then we'll press go and we are waiting for the web page and here we can see a request timed out we unable to access our of a page no dope given to the issues and to provide the solutions correct the issues if possible no we will verify the IP address of this interface Gigabit Ethernet 0 / 1 in this router r1 as per our addressing table 1 G 0 / 1 its 1 7 2.16 dot 2.1 you will try to go to r1 and we will go to CLI but I use CLI tab is locked yes so in the beginning we can see they mentioned they given a note or router r1 can only be accessed using SSH with the username admin 0 1 and password Cisco 1 2 3 4 5 ok we will access this r1 I using any one of these pieces we will use PC - 0 1 then we will go to desktop command prompt ok then we will give a SSH so that we can see its format its SSH - space - L ok the new surname so it's here admin 0 1 then target we will give giga be the third 0/0 IP address ok now its profit for the password its Cisco 1 2 3 4 5 yes now we are in r1 we will verify the IP address of the interface gigabit eternal 0 / 1 we can use a show IP interface brief command ok then press Enter gigabit a third 0/1 it's here and we can see its IP address one seven 2.16 dot 3.2 one here we can see this IP address is configured incorrectly it's a two-door to one but here we can see they configured as 3.1 no we will reassign these IP address for this interface Gigabit Ethernet 0/1 also here we can see it's certain to mask ok we will copy this IP address configure terminal then we will go to the interface giga with a third 0/1 then we will have seen the IP address the correct IP address it's here then it's a mask ok now we'll press control cert and we will verify it show IP interface brief press enter yes now it's reconfigured I think now we have to try all the communications from this PC - a again so we'll go to PC - a command prompt and we will the ping and we will try first of all we will try to ping to your server now it's here yes it's working now we will try to ping to our pcs ok one seven two dots sixteen dot one dot for it's working then 1.3 it's working no we have one more PC oh it's here it's working okay now we will go to step 4 determine connectivity issues from PC - be on PC - be opened the command prompt then enter the command ipconfig to verify the configuration for the IP address and default gateway correct as necessary coming to PC - B command prompt we will give I P config and here we can see the details coming to our addressing table here we can see its IP address 1 7 2.16 dot 2.4 it's correct then it's a damask it's correct and it's a default gateway everything correct also we will verify it's a DNS so for that we can use ipconfig /all and here we can see DNS server it's a to 0-9 + or - 1 6 5 u dot a 2 0 1.4 and the coming to a dressing table here we can see they are using the IP address of this device DNS - but all other pcs are using this a DNS 1 IP address we can verify that we'll go to PC - I will go to IP configuration and here we can see they use a 2-0 9.16 5.20 1.3 the IP address of a DNS 1 and coming to PC - 0 - here also we can see at the NS 1 IP address coming to PC - 0 1 here also we can see they use DNS 1 IP address it doesn't matter any DNS working DNS address can be used next is after correcting the IP addressing issues on PC - B issue the pings to the webserver default gateway and other pcs where the ping successful our record the results so we have to ping to our webserver then we have to ping - it's a default gateway then to other pcs first of all we will ping to our webserver we will get its IP address then coming to PC - B command prompt okay here we will the ping to our web server it's working now we will a ping to it's a default gateway it's working now we will ping two other pieces I will ping to peer PC - it's a it's a to dota 3 it's working now we will ping to PC - 0 1 it's a 1.3 it's working then also will ping to PC - 0 - it's a 1.4 it's working now navigate to www.cpa.psu.edu RL and i will close this command prompt you'll go to web browser now we will paste this a URL in this URL field then go no we unable to access the web page and here we can see the error message host name unresolved now we will try to access this web page using its IP address I mean this server IP address so we will copy this IP address we will close this the browser and we will reopen it then we will paste that server IP address in this URL field then go yes we able to access the web page using the server IP address but we unable to access the web page using it say you are now a documentary issues and provide the solutions the issues if possible but here it's not possible to correct this problem because a problem exists in this is B in this a DNS too and we don't have the permission to access this is B I mean this a DNS - server from this is B now good all the issues be resold on PC - B and still make use of a DNS - if not what would you need to do sure from this PC - B be unable to access the web page using its URL and this PC - B uses its DNS address as DNS - server IP address hence the here we have to escalate this problem to the people who is having authority to access this is B and that DNS - server finally coming to step 5 verify connectivity verify that all the PCs can access the web server www dot C squared or PKA your completion percentage should be hundred percentage if not verified that the IP configuration information is correct on all devices and that it matches what is shown in that resting table yes all these pcs can access our web server except this PC - B because it uses DNS - server IP address and now here we can see our completion status it's 100 percentage so firms in this video we discussed a packet tracer activity troubleshoot connectivity issues now T reference if you have any doubt any suggestions regarding this packet pacer activity please comment below or you can contact us using our webpage link you will get from our Facebook page and if you liked your video don't forget to give a thumb and you can share this channel or these videos to all your reference so stay tuned and we will meet again with the next video thank you
