Zusammenfassung: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.
