Damiem,
I assume you're referring to not being able to ping your own serial
interface but you can the ethernet interface? There's an "Open
Forum" question/answer on this on CCO, basically, the ping on the
serial interface is sent out over the interface, it doesn't answer it
locally.

I sometimes wonder that myself, but I don't know the answer. What
I do know is that it has to do with layer 2 encap types. For
example, frame relay interfaces - if it's a point-to-point
sub-interface, a "map" statement won't be necessary and can't
(frame-relay interface-dlci) to ping the local interface;
otherwise, you'll need a "map" statement to the local interface in
order to ping it (packets go to the other end and back). The same
goes to X25 encap, I think.HTH,Rog

3rd time to post....!!! Can anybody tell me exactly what happens in
terms of the IP stack on the
Router, when you ping an Ethernet local interface and a Serial ptp
Interface.........i.e. the packet is generated by the Router to
ping its
own interface.........where exactly the packet goes........or
software
instructions that are carried out..........
