Configuring Other Routing Protocols
Cisco IOS software on the Catalyst 4224 Access Gateway Switch supports the
following additional routing protocols:
• Novell IPX, page 12-1
• IBM SNA, page 12-4
Novell IPX
Novell Internetwork Packet Exchange (IPX) is derived from the Xerox Network
Systems (XNS) Internet Datagram Protocol (IDP). IPX and XNS have the
following differences:
• IPX and XNS do not always use the same Ethernet encapsulation format.
• IPX uses the Novell proprietary Service Advertising Protocol (SAP) to
advertise special network services. File servers and print servers are
examples of services that typically are advertised.
• IPX uses delay (measured in ticks) while XNS uses hop count as the primary
metric in determining the best path to a destination.
The Cisco Implementation of Novell IPX
The Cisco implementation of the Novell IPX protocol is certified to provide full
IPX routing functionality.
