Possible Problem Solution
Address mapping error
Step 1 Use the show running-config privileged exec command to view the
configuration of the router.
Step 2 For X.25 environments, make sure that LAN protocol-to-X.121
address mapping specified in x25 map vines interface configuration
command entries use the VINES addresses and X.121 addresses of
the destination routers. Confirm that the destination addresses used
in the command entries are correct.
Step 3 For Frame Relay environments, make sure that the LAN
protocol-to-DLCI
1
address mapping specified in frame-relay map
command entries use the VINES address of the destination router
and the DLCI of the local interface. Confirm that the destination
address and the local DLCI used in the command entries are correct.
1 DLCI = Data Link Connection Identifier
PVC
2
is not set up
2 PVC = permanent virtual circuit
Step 1
Use the show running-config privileged exec command to view the
configuration of the local and remote routers. Make sure there is an
x25 pvc n vines address interface configuration command specified
on the local and remote routers. This command sets up a PVC
between the two routers.
Step 2 If the command is not present, add it to the router configuration.
