Router not propagating RIP
updates
Step 1 Use the debug ipx routing activity privileged exec command on the
router. Look for routing updates sent by the router out each interface.
Step 2 If you do not see RIP updates being sent out the interfaces, try disabling
RIP routing using the no ipx routing global configuration command and
then reenabling it using the ipx routing command.
Use the show running-config command to verify that the rest of the IPX
configuration is still correct.
Step 3 If disabling and reenabling IPX does not work, try restarting the router.
Misconfigured network 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. You can see whether access lists are specified in an
ipx input-network-filter or ipx output-network-filter interface
configuration command.
Examples:
In the following example, access list 876 controls which networks are
added to the routing table when IPX routing updates are received on
Ethernet Interface 1:
access-list 876 permit 1b
interface ethernet 1
ipx input-network-filter 876
Routing updates for Network 1b will be accepted. Routing updates for all
other networks are implicitly denied and are not added to the routing
table.
The following example is a variation of the preceding that explicitly
denies Network 1a and explicitly allows updates for all other networks:
access-list 876 deny 1a
access-list 876 permit -1
Misconfigured network filters Step 3 If access lists are used by one of these commands, disable the filters by
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 blocks traffic from desired networks. If it does,
configure explicit permit statements for networks that you want to be
advertised normally in updates.
Step 7 After altering the access list, re-enable 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
correctly
Step 1 Use the show ipx route privileged exec command to see the IPX routing
table.
Step 2 Examine the routing table and make sure routes have been learned by the
expected protocol and from the expected interface.
Step 3 Use the show running-config privileged exec command to view the
router configuration. Check each ipx router global configuration
command entry and the associated redistribute commands, if any.
