AppleTalk Enhanced IGRP: Routers Not Establishing Neighbors

connected do not appear in the neighbor table.
Table 9-12 outlines the problems that might cause this symptom and describes solutions to those
problems.
Table 9-12 AppleTalk Enhanced IGRP: Routers Not Establishing Neighbors
Possible Problem Solution
AppleTalk Enhanced
IGRP is not globally
configured on the
appropriate routers
Step 1 Use the show running-config privileged exec command to check the
configuration of routers that should be running Enhanced IGRP. Look
for appletalk routing eigrp global configuration command entries.
This command enables AppleTalk Enhanced IGRP routing on the
router.
Step 2 If AppleTalk Enhanced IGRP routing is not enabled on the router, use
the appletalk routing eigrp router-id global configuration command
to enable it.
Make sure that the router ID is unique throughout the network.
Step 3 Perform the same actions on other routers that should be running
AppleTalk Enhanced IGRP. The router ID must be different for each
router.
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.
