IPX Enhanced IGRP: No Connectivity over IPX Enhanced IGRP Router (continued)
Possible Problem
Solution
The
ipx network
command is
missing on the
interface.
1.
Use the
show ipx interface
privileged exec command to
view the state of all IPX interfaces.
2.
If the output indicates that there are no interfaces running
IPX, or if an interface that should be running IPX is not, you
must configure the appropriate interfaces with an IPX
address.
To enable IPX protocol processing on an interface, enter the
ipx
network
number
interface configuration command.
IPX RIP is not
enabled on the
network with
connected Novell
servers.
Novell servers do not understand IPX Enhanced IGRP. You must
ensure that IPX RIP is enabled on interfaces connected to LAN
segments with attached Novell servers.
Use the
show running-config
privileged exec command on
suspect routers to view the router configuration. Make sure that
any interfaces connected to a LAN segment with attached Novell
servers have IPX RIP enabled.
It is not necessary to disable the other routing protocol, but
running IPX Enhanced IGRP and IPX RIP on the same interface
can sometimes create performance problems.
Filters have been
misconfigured.
Use the
show access-lists
privileged exec command on
suspect routers to see whether there are Novell IPX access
lists configured.
1.
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.
2.
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
commands.
3.
Check whether the client can access the server normally. If
the connection is successful, one or more access lists need
modification.
4.
To isolate the problem access list, apply one IPX filter at a
time until you can no longer create connections.
5.
Filters have been
misconfigured.
(continued)
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.
7.
After altering the access list, re-enable the filter to make sure
that 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.
