Abstract

See full text

A technique reduces consumption of resources on behalf of a router and its neighboring routers by deferring the point at which the router renders a route selection decision in accordance with a Border Gateway Protocol (BGP). A BGP KEEPALIVE message is selectively issued to enable the router to detect that each of its neighbors has finished sending all of its routes. After detecting that it has received a full set of routes from each neighbor, the router performs route selection procedures to select the preferred routes and advertises these routes to its neighbors.
