Troubleshooting Novell IPX 8-159
IPX Enhanced IGRP: No Connectivity over IPX Enhanced IGRP Router
Misconfigured filters Step 1 Use the show access-lists privileged exec command on suspect routers to
see whether there are Novell IPX access lists configured.
Step 2 Use the show running-config privileged exec command to view the
router configuration. See whether access lists are specified in an ipx
input-network-filter or ipx output-network-filter interface
configuration command.
Step 3 If access lists are used by one of these commands, disable the filters using
the no ipx input-network-filter or no ipx output-network-filter
command.
Step 4 Check whether the client can access the server normally. If the connection
is successful, one access list or more needs modification.
Step 5 To isolate the problem access list, apply one IPX filter at a time until you
can no longer create connections.
Step 6 When the problem access list is isolated, examine each access-list
statement to see whether it is blocking traffic from desired networks. If it
is, configure explicit permit statements for networks that you want to be
advertised normally in updates.
Step 7 After altering the access list, reenable the filter to make sure connections
between the client and the server still work. Continue testing access lists
until all your filters are enabled and the client can still connect to the
server.
Routes not redistributed
properly
Route redistribution between IPX Enhanced IGRP autonomous systems and
between Enhanced IGRP and other routing protocols is not enabled by default.
You must manually configure redistribution between different autonomous
systems or routing protocols.
Step 1 Use the show running-config privileged exec command on any routers
that border two Enhanced IGRP autonomous systems. Look for
redistribute protocol IPX router configuration command entries.
Step 2 If the command is not present, you must enter the appropriate
redistribute protocol command to allow route redistribution between
different autonomous systems or routing protocols.
For detailed information on configuring route redistribution, see the Network
Protocols Configuration Guide, Part 1.
Routers not establishing
neighbors properly
For information on troubleshooting this problem, see the section “IPX Enhanced
IGRP: Routers Not Establishing Neighbors” later in this chapter.
Router not propagating SAPs For information on troubleshooting this problem, refer to the section “IPX
Enhanced IGRP: SAP Updates Not Propagated by Router” later in this chapter.
