Systems and methods for a Border Gateway Protocol (BGP) route aggregation exception include advertising, to BGP peers, of a plurality of prefixes using BGP route aggregation or summarization; detecting a failure that is local to the router affecting a prefix of the plurality of prefixes; and advertising an aggregation exception that identifies the prefix to all of the BGP peers. The systems and methods can also include detecting recovery of the failure; and sending a withdrawal of the aggregation exception to all of the BGP peers.
