ABSTRACT:
Routes are withdrawn based on a query defined in a withdraw message. One or more route update messages identifying multiple routes with associated attributes and Type-Length-Values (TLVs) are received, and a routing database is updated to include the routes and their associated attributes and TLVs. A particular message associated with a route withdraw operation is received, with the particular message including an indication of at least two specified values and an operator, with each of the specified values being an attribute or a TLV. One or more routes are withdrawn from the routing database matching a query defined based on the specified values and the operator. In one embodiment, each of said attributes is a Border Gateway Protocol attribute. One embodiment includes sending a message including an advertisement of supporting MP_AGGREGATE_WITHDRAW capability.
