摘要:
In general, the disclosure describes techniques for communicating multicast group leave requests between two or more load-balanced, multi-homed PE routers included in an Ethernet Virtual Private Network (EVPN). The techniques of the disclosure enable the two or more PE routers to synchronize IGMP state and routing information amongst one another to ensure that the one of the multi-homed PE routers elected as the designated forwarder (DF) ceases forwarding the multicast group traffic to the CE router, even if it is not the PE router that receives the IGMP leave request.
