Hello Shawn,
You are correct if you do not put a map to your self you wont be able to
ping your own ip address. The reason is that the frame-relay interface uses
inverse-arp to map the frame-relay ip address to a local dlci, if you dont
have one you will not be able to ping yourself.
Sincerely,
Matijevic
