Troubleshooting IPX Layer 3 Routing
Checking the IPX Routing Table
Follow these steps to verify the IPX routing tables in the IP Layer 3 connection shown in Figure 11-21.
Figure 11-21 Displaying IPX Router Table Information
Step 1 From the Catalyst 8540-1, use the show ipx route command to verify the status of the IP routing table
for the example network shown in Figure 11-21.
C8540CSR-1# show ipx route
Codes: C - Connected primary network, c - Connected secondary network
S - Static, F - Floating static, L - Local (internal), W - IPXWAN
R - RIP, E - EIGRP, N - NLSP, X - External, A - Aggregate
s - seconds, u - uses, U - Per-user static
5 Total IPX routes. Up to 1 parallel paths and 16 hops allowed.
No default route known.
C 8510 (NOVELL-ETHER), Gi11/0/1
C 8540 (ISL vLAN), Gi10/0/1.1
C 8541 (SAP), Gi10/0/0
R 8511 [05/03] via 8510.0010.7bfa.5f1f, 12s, Gi11/0/1
R 8512 [02/01] via 8510.0010.7bfa.5f1f, 12s, Gi11/0/1
Step 2 Check the Connected primary network (indicated with a “C”). The Novell network numbers 8511 and
8512 should appear as connected through interface Gigabit Ethernet 11/0/1.
