Abstract
A method for operating an Ethernet virtual private network includes advertising, by a peer of the Ethernet virtual private network, virtual local area network routing information based on an integrated routing and bridging interface of the peer; making a determination that an Ethernet segment directly connecting a multi-homed host and the peer has failed; in response to the determination: withdrawing, by the peer, a first route of a first type of route associated with the Ethernet segment; maintaining, by the peer, a first route of a second type of route associated with the multi-homed host for a predetermined time after the Ethernet segment has failed; and forwarding, by the peer, a packet while the Ethernet segment has failed.
