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 9-14 outlines the problems that might cause this symptom and describes solutions to those
problems.

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
Note Occasional messages of this type are not a cause for concern. This is how an Enhanced IGRP
router recovers if it does not receive replies to its queries from all its neighbors. However, if these
error messages occur frequently, you should investigate the problem.
For a more detailed explanation of Enhanced IGRP Active mode, see the section “Enhanced IGRP
Active/Passive Modes” later in this chapter.
Table 9-15 outlines the problems that might cause this symptom and describes solutions to those
problems.

Older version of the
Cisco IOS software
If problems persist, upgrade to the latest release of the Cisco IOS software.
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.
