Routing Information Protocol (RIP)

RIP, which was also derived from XNS, is a protocol that allows for
the bidirectional transfer of routing tables and provides timing
information (ticks), so that the fastest route to a destination can be
determined. IPX routers use RIP to create and dynamically maintain
databases of internetwork routing information. See the last section
in this chapter for more information on routing tables.

Service Advertising Protocol (SAP)

SAP is a protocol that provides servers and routers with a method
to exchange service information. Using SAP, servers advertise their
services and addresses. Routers collect this information to
dynamically update their routing tables and share it with other
routers. These broadcasts keep all routers on the internetwork
synchronized and provide real-time information on accessible
servers on the internetwork.
