ABSTRACT:
A method and apparatus for managing network communication that operate on the idea that if a new neighboring node is already reachable as represented in a shortest path data structure that the local node consults, there is no urgency in doing a full database synchronization between the local node and the neighboring node. The present invention delays database synchronization as long as possible to reduce unnecessary OSPF packets traversing communication links between nodes of the network. Since unsynchronized neighbors remain in 2-way state, OSPF updates are not flooded over the corresponding interfaces.
