SmartSwitch Router User Reference Manual 153Chapter 9: IPX Routing Configuration GuideConfiguring IPX RIP & SAPThis section provides an overview of configuring various IPX parameters and setting upIPX interfaces.IPX RIPOn the SSR, RIP automatically runs on all IPX interfaces. The SSR will keep multipleroutes to the same network having the lowest ticks and hop count. Static routes can beconfigured on the SSR using the CLI’s ipx add route command. Through the use of RIPfilters, the SSR can control the acceptance and advertisement of networks per-interface.IPX SAPOn the SSR, SAP automatically runs on all the IPX interfaces. The SSR will keep multipleSAP’s having the lowest hop count. Static SAPs can be configured on the SSR using theCLI’s ipx add sap command. Through the use of SAP filters, the SSR can control theacceptance and advertisements of services per-interface.Creating IPX InterfacesWhen 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 ordisable 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 interfacesbound to a VLAN remain up as long as at least one port in that VLAN remainsactive.The procedure for creating an IPX interface depends on whether you are binding thatinterface to a single port or a VLAN. Separate discussions on the different proceduresfollow.IPX AddressesThe 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.
