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.
