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.
