Hi Guys,

 

     I have a question in this kind of Topology.Why WAN and BRANCH Routers can not ping its own ip address?

 

Below is the configuration of wan and branch router.

    Hi Ben,

     

    Real quick, I can see a couple of things that might help.

     

    The reason you can't ping your own interface on the multipoint interfraces is because you don't have a mapping for your own interface.

     

    Branch1

     

    interface Serial0/0.1 multipoint

    ip address 193.10.25.10 255.255.255.0

    frame-relay map ip 193.10.25.20 101 broadcast

    frame-relay map ip 193.10.25.1 101 broadcast

    frame-relay map ip 193.10.26.10 102 broadcast

    frame-relay map ip 193.10.25.10 101 broadcast

    !

    !

    interface Serial0/0.2 multipoint

    ip address 193.10.26.10 255.255.255.0

    frame-relay map ip 193.10.26.20 201 broadcast

    frame-relay map ip 193.10.26.1 201 broadcast

    frame-relay map ip 192.10.26.10 201 broadcast

     

    There is something else amiss here too.   I'll give you a hint. There is a problem with the below configuration.  Can you spot the error?

     

    interface Serial0/0.1 multipoint

    ip address 193.10.25.1 255.255.255.0

    no ip split-horizon eigrp 15

    frame-relay interface-dlci 101

    frame-relay interface-dlci 102

     

    HTH,

     

    Erick
