AURP: Routes Not Propagated Through AURP Tunnel
Possible Problems
Solution
Misconfigured
AURP tunnel
Use the show appletalk interfaces exec command to make
sure the tunnel interface is up.
1.
Use the show running-config privileged exec command to
view the router configuration. Check the tunnel source and
tunnel destination interface configuration command
entries.
2.
Exterior routers must have their tunnel interface configured
with a tunnel source and a tunnel destination command.
Make sure that the tunnel destination command on each
router points to the IP address of the remote exterior
router's tunnel interface.
3.
Missing appletalk
route-redistributi
on command
1.
If changes on the remote network are not learned through
the tunnel, use the show running-config privileged exec
command to view the router configuration. Check for an
appletalk route-redistribution global configuration
command entry.
2.
If the command is not present, add it to the configuration.
Problem with
underlying IP
network
If there are routing problems in the transit network (the IP
network through which the AURP tunnel passes), then
AppleTalk traffic might have difficulty traversing the tunnel.
To troubleshoot your TCP/IP network, follow the procedures
outlined in Chapter 7, “Troubleshooting TCP/IP.”
FDDITalk: No Zone Associated with Routes
Symptom: Routers on an FDDI ring have routes to networks across the ring, but no zones are associated
with the routes. The output of the show appletalk route command indicates “no zone set” for those
routes.
On other media, routes with no zone set are the result of other problems, such as ZIP
storms. See the sections “AppleTalk: Zones Missing from Chooser” and “AppleTalk:
Network Services Intermittently Unavailable” in this chapter for more information.
