Abstract
According to some embodiments, an Ethernet Virtual Private Network (EVPN) includes a first router configured as an Internet Group Management Protocol (IGMP) version 3 querier and a second router configured as an IGMP version 2 querier. The second router is configured to receive a Selective Multicast Ethernet (SMET) route message generated by the first router. The SMET route message includes an IGMP version 3 join request from a receiver, and the IGMP version 3 join request includes an address of a multicast source device. The second router is further configured to convert the IGMP version 3 join request of the SMET route message to an IGMP version 2 join request. The second router is further configured to send multicast traffic from the multicast source device to the receiver via the first router.
