Abstract

In one embodiment, a router selects a particular peer from an original update group used with an Exterior Gateway Protocol (EGP) such as Border Gateway Protocol (BGP). The original update group includes a plurality of peers of the router that share a same outbound policy and that receive common update messages, from the router, of routing table information. The router determines that the particular peer is a potential slow peer based on a first type of indicia, wherein a slow peer is a peer that cannot keep up with a rate at which the router generates update messages over a prolonged period of time. The router confirms that one or more second types of indicia are consistent with the particular peer being a slow peer. In response to the confirmation, the router determines that the particular peer is a slow peer.
