Routing Information Protocol (RIP)
Figure A-2 shows an example of a router between networks A and B.
If node A sends a packet to node B, the IPX header for the packet contains the following
information:
The MAC header is set up as follows:
When the router receives the packet, it checks the destination address in the IPX packet
header and consults the packet’s routing table for the shortest route to the destination
network. The router forms a new MAC header:
The packet is then routed to node B, its final destination.
RIP enables NetWare servers or dedicated router devices to create and update a table of
internetwork routing information. Servers or routers on an internetwork send out
periodic RIP broadcast packets that contain routing information to maintain current
information in their routing tables. Workstations send RIP requests to the nearest router
to find the fastest route on a network.
