Hi Jeevesh, Actually DSDV doesn't have the all the neighbours's routing table with it, at the time of calculation of shortest path. it has got only necessary information gathered by the neighbor nodes during triggered and periodic update. It gets the routing update packet from its neighbors, and compare this packet with its routing table. Necessary updates will be implemented. But not all the table stored by this node.
