Abstract
A technique allows selective generation of routing update messages by a router for its neighboring peer routers of a computer network. When an entry version number of a route is incremented, the reason (i.e., “what has changed”) for the change in the best path of the route is identified and recorded. Recordation of the reason is effected using change flags. These flags, along with the characteristics of each neighbor peer router, are considered when determining whether the route is eligible for further consideration of routing updates to the neighbor.
