Abstract
A mechanism limits the flow of topology information to only those nodes of a computer network that require the information. The mechanism comprises a filter having a plurality of conditions that are evaluated by a node of the network prior to forwarding the topology information to another node. Specifically, the conditions are evaluated with respect to lists of nodes that are defined according to the configuration of the network. By applying the filtering conditions to the defined lists, each node may selectively propagate the topology information throughout the network, thereby substantially reducing the amount of information flowing over the network.
