16.3.1 Packet Tracer - Troubleshoot Static and Default Routes

troubleshoot static and default routes addressing table for these three routers a one r2 and r3 r1 r2 and r3 pc1 pc2 and the server pc1 pc2 and the server ipv4 and ipv6 addresses locate and document the problems okay identify location the problem and the solution okay for example go to pc1 command prompt and pink pc2 okay pc2 ip address is once that they do 31 0 to 54 being 170 2 3 1 0 to 54 enter okay request timeout ping face ping fails so review r1 configuration go to [Music] r1 enter enable show ib root okay you have two directly connected networks one two directly connected networks and one a study group that is the default route using 172 31 one 195 the net hop address for r1 is the serial 0 on r2 so this ip address should be the serial the ip address of serial 0 0 on r2 and the serial 000 on r2 the ipv4 address is 172 31 1 193 but in this case is 172 195 so it should be 193 you can see this on show running config show running config op space space and look at this the default static route and the nut hub is 195 and it should be 193 space configure terminal no ip routes the forward and remove this this default route once i need 231 one 195 172 3d one one 195 okay now ipro default static and the let's hope enter okay and set the correct that should be 193 the serial 0 or r2 okay remove only ip root the folders at the root 172 31 1 193 and very good okay and go pc1 and pink pc2 ipv4 rounds okay from pc1 pc2 okay pin fails okay pin fails but r1 configuration is okay the problem is placed now and on another side for example r2 okay to reach from pc1 to pc2 if r1 is okay r2 is the problem so review r2 configuration enter enable show ip roots now you can see three directly connected networks one two three okay one two three okay and two static routes two static rules the third static route is the destination is 172 31 1 0 25 okay is this 172 31 1 0 25 this is the destination okay r2 will reach this this network 172 31 1 0 25 okay this and the next hop is 172 31 1 198 for r2 the net scope to reach this network is this serial 0 0 on r1 and should be 172 31 198 okay review serial zero zero on r1 and the ip address of serial zero zero zero on r1 is 172 31 194 okay and and r2 is 172 31 1 198 and should be 194 okay so we change this okay also you can see this on show running config command show running show running config and this is remove this and change 198 and use 194 okay so remove this configure view terminal no ip root okay 172 31 1 0 128 172 31 1 0 128 is 1 25 285 255 128 172 31 1 198 172 311 okay now and the commands okay remove enter and now configure the correct the correct route ip route 17231 one zero and submit mask that is this network the destination okay and should be 194 okay because the net scope of r2 to reach this network is serial 0 0 on r1 and is serial 0 r1 should be 194 okay this is enter very good and now review the the another the another the another static route okay to reach 172 31 one 128 26 okay to reach this network 172 31 128 26 use the nutshot 172 381 194 and for r2 to reach this network the nut scope is serial zero zero one on r3 okay on r3 serial zero zero one is one seventy two thirty one one one ninety eight go to r2 and is 194 so change this okay it should be 198 198 serial 0 0 1 on r3 serial 0 1 on r3 198 okay so change this okay you can see here the destination 128 okay this destination 128 subnet mask 192 very good is 26 but is 194 and use 198 okay remove this no ibu 172 31 1 128 182 172 301 1 128 285 255 285 182 and remove this and remove this 172 31 194 172 31194 remove this 194 remove this and should be 198 okay ip root 172 311 128 subnet wire some net mass 182 let's hop 132 31 1 198 okay and now review and show iproot to reach 172 31 1 zero 25 to reach this network the net scope for r2 is serial 0 on r1 serial 0 0 0 0 0 r1 is 194 okay very good 194 and to reach 172 31 128 26 to reach this network on r2 the net scope is 172 31 198 and then that's how to reach this network for r2 is serial 001 on r3 on r3 001 is one idea very good and now from pc one pix to pc2 go to pc1 and repeat pink ones id2 theory 1 0 to 54 enter and now success and now from pc1 ping the server the server ipv4 address is 172 3119 pin 172 31 1 190 enter okay pink is failing vaping fails so r1 configuration is okay r2 configuration is okay review our three configuration enter enable show ib root okay and two directly connected networks okay two directly connected networks one two go to r3 three static routes three static routes okay the first a static route 172 31 zero zero 24 is the destination okay 172 through the one zero zero 24 is the destination okay and the next hub is in this case uses the local interface here l01 the local interface is serial 001 very good okay so you can see this also on show running coffee space space space space okay destination 17231 0 0 and serial 001 destination 172 3100 and the local interface to reach this network on r3 the local interface is serial 001 it's ok very good now review the another static route the destination is what's 8231.1028 this is the network 172 3110 172 3110 local interface is serial 001 the local interface is serial 001 to reach this network and is very good but the subnet mask should be 25 and 13 says 28 also you can see this on the show running destination 170 172 311 and 240 is 28 but should be 25 and 25 is not 240 25 is 128 128 here and using cdl001 okay so remove this configure configure terminal no ap root the destination this network okay 172 31 okay 172 31 1 0 240 one zero two eighty five divided by 255 to 40 and using serial zero zero one using cl001 okay now to remove all these commands to remove all these okay enter and add the new the new correct route ip rule1723110 instead of using two for the s120a 128 is 25 graphics okay go to r3 serial zero zero one serial zero zero one one r3 very good enter okay and don't worry about this message okay exit show iproot to verify okay and this is the destination 172 31 1 0 25 172 31 1 0 25 you see in serial interface serial zero zero one the local interface serial zero zero one on r3 very good and rebuild this another static rule 172 31 192 30 172 31 1923 very good and serial zero zero one okay to reach this network using serial zero zero one very good so this is okay don't don't problem not problem okay and now from pc one pick the server again go to pc1 and ping 172 3119 190 success okay and now try ping from pc1 to pc2 using ipv6 ping being to pc2 pc2 ipv6 addresses 2001 dba 3 colon colon 254 2 0 0 1 dba 3 colon column 254 enter okay and ping is failing pink is failing request timeout okay pin face review r1 enable show ipv6 root space directly ignite the network directly connected network okay two directly connected networks one two and three static routes three static routes and review these static routes the first uh two zero zero one dba three column column prefix 64. okay is this 2001 dba 3 colon column prefix 64 very good go to r1 using serial 0 okay using serial 0 okay so this is okay okay very good now the another two zero zero one db eight four column column sixty four okay two zero zero one db eight four column column sixty four very good serial 00 okay to reach this network using serial 0 0 and r1 very good so this is okay and now the another uh 2001 db85 color colon 64 2001 db85 colon colon 64 very nice serial zero zero zero zero zero zero zero okay very good so r1 is very well configured so go to r2 show ipv6 root space and you have one two three three directly connected networks one two and three three directly connected networks and one and two two static okay review the fields 2001 db6 column 1 column column 64. okay and now 2001 db6 network or subnet all subnets using 2001 db8 okay so this is this should be db db8 not db6 okay 2 0 0 1 db 8 column 1 column column 64. okay and it should be this 2001 dba column 1 column column 64 should be this okay and the math scope is 2001 dba to column column 194 so on r2 to reach this network the net scope is serial 0 0 ipv6 address on r1 okay on r1 serial 0 0 ipv6 2 0 31 dba 2 colon colon 194 okay one knight d4 2 0 01 dba 2 column colon 194 so this is okay the only change should be db8 okay you can see this also on show running config space space okay and is this ibvc through 2001 db6 column 1 164 and the nut scope 2001 dba 2 column column 184 okay this is okay then let's hop is okay we change this to db8 and remove this and remove this command space configure configure terminal no ipv6 zero root one two zero zero one db six one column column sixty four t zero zero one db six column one column column sixty 64. in the next hop to column column 194 2 0 0 1 dba 2 column column 184 okay dba 2 184 dba 2 column column 184 very good remove this remove this command enter and now configure this the correct the correct route to zero zero one dba repeat the command and change ipvc true crew 2001 db8 one chronograph 64. let's hop to zero zero one dba two column column one and e4 enter okay and and review show ipv6 rules okay 2031 db8 one column column 64. okay this and the nut scope 194 okay very good and now okay and review this another static route destination two zero zero one dba five column column sixty four two zero zero one db eight five column column sixty four very good okay and review this another static root two zero 2001 db85 colon colon 64 2 0 0 1 db 8 5 colon collox 64 okay and the nut hop 198 4 colon colon 198 okay and r2 to reach this network the nut scope is zero zero zero one on r3 or three serial zero zero one four column column two zero zero one db84 column column 198 okay on r2 198 very good and all is okay so from pc one ping pc2 pc1 repeat three column column 254 three column column 254 pc2 enter success and finally from pc one pick the server the server is five column column one id 0 0 1 dba 5 column column 1 9 enter okay request timeout ping phase now r1 is okay r2 is okay go to r3 show ipv6 root okay review the first okay two directly connected networks one and two and on r3 one two two a static two static routes okay the first static route is two zero zero one dba two column column sixty four two zero zero one dba two column column 64 very good using serial 01 okay using serial 01 very good to reach this network very good and then another static route 2001 dba 3 column column 64 2001 dba 3 colon column 64 very good using serial 0 0 1 using serial 0 0 1 very good and no more static roots and i need a steady route to reach lung one this network two zero zero one db8 one column colon 64. and it's not it's not here so configure that configure terminal ipv6 route the destination 2001 dba okay this one column column prefix 64. and using serial 01 on r3 serial 0 0 1 and i'm very good and from pc1 ping the server from pc1 pick the server 5 190 enter okay the server 5 190 very good okay completion 100 thank you very much you
