Mainly the distance vector name comes from the information of the periodic messages. Basically, a message contains a list of pairs of V and D where V corresponds to the destination and D is the distance to that destination. Also, note that the distance vector algorithms report the routes of the first persona and the router advertises that it had reached the destination V at a distance of D. It’s very important that all routers must participate in the distance vector exchange for the routes which are efficient and consistent.
Basically, a working of the distance vector algorithms is simple. The router keeps the list of all the known routes in the table. When it boots, the router initializes the routing which initializes the routing table which contains the entry for each directly connected network. Every identity in the table accommodates the destination network and reports the distance to the network. For example, the initial contents of the table in the router which attaches to two networks which can be seen with the difference between the two networks. The initial distance vector routing table with an entry for every directly connected network. Now, each entry contains the IP address of a network and then the integer distances to that network.

Periodically each router sends a copy to the routing table, if any router it can accommodate then it will reach directly to the report which arrives at the router which J, K determines the set of destinations which are reported and the distance to which the same device reports the shorter way to reach on the network. Note that if the J reports the N, then an updates entry in the K will have the distance N+1. The next hop entry in each initial route changes rapidly after which the computing which stabilizes after an interval of the distance traveled from J to K. Some of the routers may have incorrect routing information which mainly depends on the network used.
