Distance vector routing is a routing algorithm where each router maintains a routing table with the best routes to other routers in the network. The tables are dynamically updated as routers exchange information with their neighbors about changes in route distances. Each router knows the optimal path to every other router by keeping track of the next hop and distance to each destination router based on information from neighbors.

2. Distance Vector Routing
1. It’s an adaptive or dynamic programing
2. Each router maintains a table called “vector”
3. Table has best known distance for each router
4. Tables are updated by exchanging information with neighbours(Routers)
5. Each router knows the best distance to reach another router
6. Also known as Bellman-Ford Routing Algorithm.

3. Distance Vector Routing
Each Router’s Table has one entry for one router :
This entry has two parts
1. Preferred outgoing line for each Router
2. Estimated distance to destination Router
Distance is basically considered by number of Hops.
Delays basically measured by sending ECHO packets to another
routers.
