IPX Enhanced IGRP: Routers Not Establishing Neighbors
Symptom: IPX Enhanced IGRP routers do not establish neighbors properly. Routers that are known
to be connected do not appear in the neighbor table.
Note Procedures for troubleshooting IPX Enhanced IGRP problems not specific to establishing
neighbors are described in the section “IPX Enhanced IGRP: No Connectivity over IPX Enhanced
IGRP Router” earlier in this chapter.
Table 8-9 outlines the problems that might cause this symptom and describes solutions to those
problems.
Table 8-9 IPX Enhanced IGRP: Routers Not Establishing Neighbors
Possible Problem Solution
Routers are in different
autonomous systems
Step 1 Neighbor relationships will not be established between routers in
different autonomous systems. Make sure the routers you want to be
neighbors are in the same autonomous system.
Step 2 Use the show running-config privileged exec command to view the
router configuration. Check the ipx router eigrp command entries to see
which autonomous systems the router belongs to.
Hello or hold-time timer
mismatch
Step 1 Use the show running-config privileged exec command on each router in
the network. Look for ipx hello-interval eigrp and ipx hold-time eigrp
interface configuration command entries.
The values configured by these commands should be the same for all IPX
routers in the network.
Step 2 If any router has a conflicting hello interval or hold-time value,
reconfigure it to conform with the rest of the routers on the network.
You can return these values to their defaults with the no ipx
hello-interval eigrp and no ipx hold-time interval eigrp interface
configuration commands.
Link problem
Step 1 Use the show interfaces privileged exec command to check whether the
interface is up and functioning correctly.
The following is sample output from the show interfaces command:
Router#show interfaces fastethernet1/0
FastEthernet1/0 is up, line protocol is up
Hardware is cyBus FastEthernet Interface, address is
0010.5498.d020 (bia 0010.
5498.d020)
Internet address is 210.84.3.33/24
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely
230/255, load 1/255
Encapsulation ARPA, loopback not set, keepalive set
(10 sec), hdx, 100BaseTX/FX
Step 2
Use the show ipx eigrp neighbors privileged exec command to make
sure all Enhanced IGRP neighbors are shown in the neighbor table.
Step 3 If not all neighbors are in the neighbor table, there might be a link
problem. Refer to other chapters in this book for information on
troubleshooting specific link types.
