Routing Table Maintenance Protocol (RTMP)
The Bay Networks AppleTalk router uses the Routing Table Maintenance Protocol
(RTMP) to create and maintain the routing information DDP uses to transmit
packets across an internet. Routing information is contained in the AppleTalk
routing table.
Each table entry includes the following:
• Destination network range
• AppleTalk protocol address (network number and node number) through
which the destination is reached
• Number of router hops to the destination
• Route status
Routers create and update their routing tables by periodically constructing and
broadcasting RTMP data packets to all other routers on directly connected links.
An RTMP data packet contains the source address and the information stored in
the originating router’s routing table. All routers receiving the data packet use this
information to update their own routing tables (F
igure 1-5).
