METHOD AND DEVICE FOR PROCESSING MULTICAST MESSAGE IN NVO3 NETWORK, AND NVO3 NETWORK

摘要

The present invention provides a method and an apparatus for processing a multicast packet on an NVO3 network, and an NVO3 network. The first multihoming NVE receives a first multicast packet sent by a multihomed TES; acquires an ingress port of the first multicast packet and a virtual local area network identifier VLAN ID of the first multicast packet, acquires a virtual overlay network identifier VN ID of the first multicast packet according to the ingress port and the VLAN ID of the first multicast packet, determines whether the ingress port is a designated forwarder DF of the VN ID of the first multicast packet; when the ingress port is not the DF of the VN ID of the first multicast packet, encapsulates the first multicast packet with an extended NVO3 header, and sends the first multicast packet that is encapsulated with the extended NVO3 header to another NVE that includes the second multihoming NVE, where the extended NVO3 header carries the VN ID of the first multicast packet and a link aggregation group identifier LAG ID that corresponds to the ingress port. The present invention can solve a problem that is of IP address wasting and is caused in an all-active or active-active TES access scenario.
