Abstract
A system for exchanging routing information over a communications network constructs a connectivity graph that indicates connectivity between a first node and a first set of nodes in the network. The system constructs an adjacency graph that indicates a second set of nodes with which the first node will exchange routing data, where the adjacency graph is distinct from the connectivity graph. The system exchanges routing data between the first node and each node of the second set of nodes based on the adjacency graph.
