IPX Connectivity Problems (Duplicate ID or Network Number)

To establish an IPX connection to third-party routers over a WAN, the
third-party routers must support IPXWAN; otherwise, problems with
initiating, maintaining, or terminating the IPX connection occur.
8
Verify that the IPX network number is different for each WAN link unless
an unnumbered RIP is used (in which case, the IPX network number is
zero).
To isolate and resolve IPX connectivity problems, complete the following
steps:
1
Find the server or router that is connected to the same segment as the
workstation.
If more than one server or router connects the workstation to the network,
look at each system to determine if it has proper connectivity. If the
system with which you are communicating is a server, then use that
system.
2
Check the forwarding table on both systems.
2a
If you are on the server or router representing network A, then find
network B in the forwarding table. Load IPXCON (parameter path:
Select Forwarding > Display entire forwarding table).
2b
If network B is not displayed in the table, then exit and enter the
forwarding table until it appears.
2c
If network B still does not appear in the table, probably a router in the
path either is malfunctioning or has a duplicate system ID.
2d
If the route shows up intermittently, then probably a router in the path
has a duplicate system ID.
2e
If the route shows up consistently, then look at the route and select
Potential Paths by selecting the network on the Forwarding Table
menu.
3
Make sure that the potential path leads to the correct network by looking
at the intermediate routers.
If a duplicate network number exists, you can determine the location of
the duplicate number from this window.
3a
If all the routers in the path seem to be correctly configured, then
write down the addresses of all the LANs and routers in the path.
