140.1.1??? output is the remote router IP address (a dynamic entry that is learned
through the Inverse ARP process).
?– Broadcast and multicast are enabled on the PVC because broadcast is stated in the third
line.
?– The PVC status is active.
To clear dynamically created Frame Relay maps, which are created using Inverse ARP, use
the clear frame-relay-inarp privileged EXEC command.
Summary of Establishing a WAN Connection with Frame Relay
The following summarizes the key points that were discussed in the previous sections:
?– Frame Relay PVCs are identi?¬?ed with DLCIs, and the status of the PVCs is reported
through the LMI protocol.
?– Frame Relay point-to-point subinterfaces require a separate subnet for each PVC, and
multipoint subinterfaces share a single subnet with Frame Relay peers.
?– To display connectivity with the Frame Relay provider, use the show frame-relay lmi
command. To display connectivity with the Frame Relay peer, use the show framerelay
pvc and show frame-relay map commands.
Troubleshooting Frame Relay WANs
A Frame Relay network offers a few additional bene?¬?ts that a leased-line implementation
does not offer. But with these bene?¬?ts comes a bit more complexity.
