RIP Control Menu
RIP sends routing-update messages at regular intervals. When a router receives a routing
update that includes changes to an entry, it updates its routing table to reflect the new route.
The metric value for the path is increased by 1, and the sender is indicated as the next hop.
RIP routers maintain only the best route (the route with the lowest metric value) to a
destination. After updating its routing table, the router immediately begins transmitting
routing updates to inform other network routers of the change. These updates are sent
independently of the regularly scheduled updates that RIP routers send.
In general, when a router sends a routing update, the following authentication sequence
occurs
1. A router sends a routing update with a key and the corresponding key number to the
neighbor router.
2. The receiving (neighbor) router checks the received key against the same key stored in its
own memory.
3. If the two keys match, the receiving router accepts the routing update packet. If the two
keys do not match, it rejects the routing update packet.
Using the RIP Control menu, you can configure the way how the Gateway adjusts to
physical changes in the network’s layout and exchange routing tables with other routers. To
access the RIP Control menu, click Routing in the menu bar and then click the RIP Control
submenu. Figure 46 shows an example of the menu and Table 21 describes the options.
