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.

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..........
