RIP sends routing-update messages at regular intervals and when the

network topology changes. When a router receives a routing update that

includes changes to an entry, it updates its routing table to reflect the new

route. RIP routers maintain only the best route to a destination. After

updating its routing table, the router immediately begins transmitting

routing updates to inform other network routers of the change.

Poison Reverse A method for preventing loops that would cause

endless retransmission of data traffic.

Authentication Required • None: No authentication.

• Password: A password authentication key is

included in the packet. If this does not match

what is expected, the packet will be discarded.

This method provides very little security as it

is possible to learn the authentication key by

watching RIP packets.

Authentication Code Password Authentication key.
