Chapter 16: IPX Routing Configuration Guide
Configuring IPX RIP & SAP
This section provides an overview of configuring various IPX parameters and setting up
IPX interfaces.
IPX RIP
On the SSR, RIP automatically runs on all IPX interfaces. The SSR will keep multiple
routes to the same network having the lowest ticks and hop count. Static routes can be
configured on the SSR using the CLI’s
ipx add route command. Through the use of RIP
filters, the SSR can control the acceptance and advertisement of networks per-interface.
IPX SAP
On the SSR, SAP automatically runs on all the IPX interfaces. The SSR will keep multiple
SAPs having the lowest hop count. Static SAPs can be configured on the SSR using the
CLI’s
ipx add sap command. Through the use of SAP filters, the SSR can control the
acceptance and advertisements of services per-interface.
Creating IPX Interfaces
When you create IPX interfaces on the SSR, you provide information about the interface
(such as its name, output MAC encapsulation, and IPX address). You also enable or
disable the interface and bind the interface to a single port or VLAN.
Note: Interfaces bound to a single port go down when the port goes down but interfaces
bound to a VLAN remain up as long as at least one port in that VLAN remains
active.
The procedure for creating an IPX interface depends on whether you are binding that
interface to a single port or a VLAN. Separate discussions on the different procedures
follow.
Note: You cannot assign IPX interfaces for LAN and WAN to the same VLAN. In order
for these two types of IPX interfaces to coexist on the SSR, each type must be
assigned to different VLANs.
IPX Addresses
The IPX address is a 12-byte number divided into three parts. The first part is the 4-byte
(8-character) IPX external network number. The second part is the 6-byte (12-character)
node number. The third part is the 2-byte (4-character) socket number.
