Hi Jeevesh, DSDV stores the Routing table for each node that is modified by the information received by the node's neighbor nodes. "rtable.h" file contains "class RoutingTable" and rtable.cc stores each entry, contains information about the current node's neighbors, into rtable_ent *rtab member variable of RoutingTable class. In dsdv.cc, makeupdate function builds a packet which contains information about the current node's neighbors. if updatetype=1, all of the records hold by the rtab member will be send, else appropriate records will be send. I hope, this answer helps you.
