difference is that each point-to-point subinterface is a different IPX network, as seen in Figure
5-38. Otherwise, SAP and RIP are enabled globally with the ipx routing command; each is
allowed to be broadcast on interfaces (or subinterfaces) with the ipx network interface
subcommand. SAP and RIP updates are sent out each subinterface--this means that Atlanta
will replicate and send three copies of the RIP update and three copies of the SAP update on its
serial0 interface, one per subinterface, every 60 seconds.
be reviewed. In Figure 5-38, assume that Gary is an old NetWare client running NetWare
version 3.11 client software and using the Ethernet_802.3 Novell encapsulation. Stephanie is
newer and uses the Ethernet_802.2 encapsulation. Two IPX networks are used on Nashville's
Ethernet 0 interface in this case.

Example 5-26 also shows an alternative configuration using subinterfaces.
