  • three router basic setup

    ISP<---serial--->Lab_A<----serial---->Lab_B

    This is all in Packet Tracer. All is required is being able to ping from one router to another. (Not through network for now). Can ping from ISP to Lab_A, and from Lab_A to Lab_B, but the Packet Tracer gives failed error message when pinging from Lab_A to Lab_B, even though the ping is successful using CLI. Never had this problem before. What am I missing?

    From which IP to which IP are you pinging?
    if you are pinging to the inside addresses where is your routing config/table?

      Re: three router basic setup

      I'm not looking to ping across the network. I just want to be able to ping between the immediately connected routers.
      Many thanks.

      ISP#sh ip route

      Gateway of last resort is 0.0.0.0 to network 0.0.0.0

      171.16.0.0/24 is subnetted, 1 subnets
      C 171.16.10.0 is directly connected, Serial0/1/0
      S* 0.0.0.0/0 is directly connected, Serial0/1/0


      Lab_A#sh ip route

      Gateway of last resort is not set

      171.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
      S 171.16.0.0/16 [1/0] via 171.16.10.1
      C 171.16.10.0/24 is directly connected, Serial0/1/0
      C 192.168.20.0/24 is directly connected, Serial0/1/1



      Lab_B#sh ip route

      Gateway of last resort is not set

      C 192.168.20.0/24 is directly connected, Serial0/1/0
      C 192.168.30.0/24 is directly connected, FastEthernet0/0

        Hope this helps.

        ISP
        (171.16.10.1/24)<----->(171.16.10.2/24)Lab_A(192.168.20.1/24)<----->(192.168.20.2/24)Lab_B

            hmmm cisco is producing good software then, like there SDM..
            I'd rather go for GNS3 then.

            Glad you solved it and thanks for posting back...
