use the RIP/SAP routing protocol to communicate with each other. RIP
enables routers to send out periodic updates of service and routing
information. The internetwork topology is shown in

To minimize the load on the WAN link, an IPX SAP filter is configured on
Router 1 and Router 2. This filter cuts down the periodic service information

clients across the WAN link can access the servers on the other network by
first attaching to these selected servers.
