Hi,
In multipoint interface, if you donot define a map pointing to self ip
address, frame relay donot know which dlci to send the icmp, and will show
"encapsulation failure". In point-to-point interface, There is only one dlci
over there, frame relay just send the icmp over it. so, even you ping self
ip address, the icmp packet is send to the other end, which will send
response back.
Bin.
