IPX Routing in the NetWare® Environment 6-3

Routing RIP allows the exchange of routing information on a NetWare network. IPX Information routers use RIP to dynamically create and maintain their routing tables.

Protocol (RIP)

RIP allows one router to exchange routing information with a neighboring router. As a router becomes aware of any changes in the network layout, it broadcasts this information to any neighboring routers. IPX routers also send periodic RIP broadcast packets containing all routing information known to the router. These broadcasts synchronize all routers on the network and age those networks that might become inaccessible if a router becomes disconnected from the network abnormally.

Service Advertising SAP provides routers and servers that contain SAP agents with a means of Protocol (SAP) exchanging network service information.

Through SAP, servers advertise their services and addresses. Routers gather this information and share it with other routers. This strategy allows routers to dynamically create and maintain a database (server table) of network service information. Clients on the network can determine what services are available and obtain the network address of the nodes (servers) where they can access those services. Clients require this information to initiate a session with a file server.

SAP allows one router to exchange information with a neighboring SAP agent. As a router’s SAP agent becomes aware of any change in the network server layout, it immediately broadcasts this information to any neighboring SAP agents. The router also periodically sends SAP broadcast packets containing all server information known to the SAP agent. These broadcasts synchronize all servers on the network and age those servers that might become inaccessible because of any abnormal shut down of the router or server.
