Figure A-12 IPX Network Numbering Plan

IPX Node Numbering

IPX uses a 48-bit address for the node. The IPX device will use the data link address of one

interface as its IPX node address. Because the Layer 3 address is the same as the Layer 2

address, there is no need for an ARP process to perform network-to-data link layer address

resolution.

IPX Routing Protocols

Cisco IOS software supports the following IPX routing protocols:

• IPX RIP

• IPX enhanced IGRP

• Novell Link State Protocol

IPX RIP is enabled by default. Enter the EXEC command sh ipx route to examine the IPX

routing table in an access server running Cisco IOS software.
