Systems and Methods for Supporting Mixed IGMP Querier Versions

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.
