2. If the keepalive is not set, enter the config-
uration mode and enter the keepalive interval
on the proper interface.
Encapsulation type
1. Verify that the encapsulation type is the same
on both routers. If non-Cisco equipment is
used, the encapsulation must be set for IETF.
You can display this information by using the
show frame-relay map
command.
2. The encapsulation can be changed by
using the encapsulation frame-relay
ietf
command.
DLCI mismatch
1. Use the show running-config command to
display the DLCI number assigned to the
proper interface. The show frame-relay pvc
command can also display the DLCI assigned
to the interface.
2. If the correct DLCI number is configured on
the proper interface, contact the local carrier
to verify that it has the same DLCI configured
on the Frame Relay switch.
Access List problem
1. Use the show ip interface command to
display the access list applied to the interface.
2. Analyze the access list, and then remove
and modify it, if necessary.
