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.

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.
