Abstract
An improved technique for distributing routing information that allows routes to be prioritized such that information associated with higher priority routes is sent in update messages ahead of information associated with lower priority routes, thereby enabling the higher priority routes to converge faster than the lower priority routes. In the preferred embodiment of the invention a route policy map that associates routes with priorities is defined. The policy map is then applied to the routes to prioritize the routes. Update messages are then generated using the priority information and the route information contained in the update messages is organized such that route information associated with higher priority routes is placed ahead of route information associated with lower priority routes.
