Distance Vector Routing Protocol (DVR)

Distance Vector Protocols advertise their routing table to every directly connected neighbor at specific time intervals using lots of bandwidths and slow converge.

In the Distance Vector routing protocol, when a route becomes unavailable, all routing tables need to be updated with new information.

Advantages:

• Updates of the network are exchanged periodically, and it is always broadcast.
• This protocol always trusts route on routing information received from neighbor routers.

Disadvantages:

• As the routing information are exchanged periodically, unnecessary traffic is generated, which consumes available bandwidth.
