AppleTalk Enhanced IGRP: Routes Missing from Routing Table
Possible Problem
Solution
Routers not
establishing
neighbors
properly
For information on troubleshooting this problem, see the section
“AppleTalk Enhanced IGRP: Routers Not Establishing
Neighbors” earlier in this chapter.
AppleTalk
Enhanced IGRP is
not enabled on
interfaces
Use the
show running-config privileged exec
command on
routers that are running Enhanced IGRP. Check the interface
configurations for
appletalk protocol eigrp
interface
configuration command entries.
This command must be present in order for an interface to
generate AppleTalk Enhanced IGRP hello messages and routing
updates.
Older version of
the Cisco IOS
software
If problems persist, upgrade to the latest release of the Cisco IOS
software.
AppleTalk Enhanced IGRP: Poor Performance
Symptom:
Network performance in an AppleTalk Enhanced IGRP environment is poor. Connections
between clients and servers are slow or unreliable.
Table 9-3 outlines the problems that might cause this symptom and describes solutions to those
problems.
Table9-3
AppleTalk Enhanced IGRP: Poor Performance
Possible Problem
Solution
AppleTalk
Enhanced IGRP
and RTMP are
running
simultaneously on
the same interface
Use the
show running-config privileged exec
command on
network routers. Check the interface configurations to determine
whether AppleTalk Enhanced IGRP and RTMP are both enabled
on the same interface.
Running both AppleTalk Enhanced IGRP and RTMP on the same
interface increases bandwidth and processor overhead.
Determine whether both routing protocols need to be running on
the interface and disable one or the other if necessary or desired.
Older version of
the Cisco IOS
software
If problems persist, upgrade to the latest release of the Cisco IOS
software.
AppleTalk Enhanced IGRP: Router Stuck in Active Mode
Symptom:
An AppleTalk Enhanced IGRP router is stuck in Active mode. The router repeatedly sends
error messages similar to the following to the console:
%DUAL-3-SIA: Route 2.24 Stuck-in-Active
