next site and if there is any, forwards the packet. The routing information can be
configured statically or collected dynamically.
This chapter introduces RIP in IPX. For the RIP configurations on an IP network,
refer to the routing protocol section in this manual.
Service Advertising
Protocol
The Service Advertising Protocol (SAP) advertises the services provided by servers
and their addresses. It is used by IPX to maintain and advertise dynamic service
information. With SAP, a server broadcasts its services when it starts and the
termination of the services when it goes down.
With IPX enabled, the switch creates and maintains an internetwork service
information database (or the service information table) through SAP. It helps you
learn what services are available on the networks and where they are provided.
The servers periodically broadcast their services and addresses to the networks
directly connected to them. Users cannot use such information directly, however.
Instead, the information is collected by the SAP agents of the switches on the
networks and saved in their server information tables.
