摘要： 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.

摘要： In one embodiment, a method includes receiving, by a route reflector, a subscription request from a first provider edge node in a network and generating a subscription policy for the first provider edge node. The method also includes receiving a first Ethernet Virtual Private Network (EVPN) Type 2 Route from a second provider edge node, assigning a sequence number to the first EVPN Type 2 Route, and communicating the first EVPN Type 2 Route with the sequence number to the first provider edge node. The method further includes receiving a second EVPN Type 2 Route from a third provider edge node, generating an updated sequence number in response to receiving the second EVPN Type 2 Route from the third provider edge node, and communicating the second EVPN Type 2 Route with the updated sequence number to the first provider edge node and the second provider node.
