Re: own-interface:No Ping...

Frame-relay utilizes NBMA (Non-Broadcast Multiple Access).

As the name implies, it doesn't broadcast the packets so you need to tell it where to go.

On every serial connection, the packet leaves the interface - goes to the neighbor router and returns - including a ping to the router's local serial interface (try it on a point-to-point or hdlc interface).

In Frame-Relay, the router relies on dynamic inARP or static for its mapping.

The mapping instructs the router where to send the packet via that interface, therefore you need to have a mapping for the router's local interface pointing to the neighbor interface. On this scenario, the packet knows where to go and the neighbor router knows where to send it back.

Another choice is configuring a point-to-point subinterface. On this situation, the router knows it only has one neighbor and it sends everything out that interface to that neighbor. If the neighbor is up, it will respond to the ping.

Re: own-interface:No Ping...

IPv6 does not need a self-mapping to a remote host's DLCI as it creates a local route for the serial interface on its routing table (see the output from typing show ipv6 route).

Re: own-interface:No Ping...

That's the link-local address.

Please have a read to these IPv6 chapters
