    abstract =  {Ethernet VPN (EVPN) networks support multicast applications in which multicast routers and multicast hosts are attached to the same tenant. Existing specifications define how Provider Edge (PE) devices synchronize the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) membership state of multihomed multicast hosts, and how Optimized Inter-Subnet Multicast (OISM) forwarding interacts with multicast routers via PIM EVPN Gateways. However, none of the existing specifications addresses the synchronization of the state associated with a multicast router (an IGMP/MLD Querier or a Protocol Independent Multicast (PIM) router) when that router is multihomed to a set of EVPN PEs. This document specifies a new EVPN route, the Multicast Router Discovery (MRD) route, and the procedures to synchronize multicast router state across the PEs of an Ethernet Segment, for routers attached to multicast Broadcast Domains or to Layer 3 interfaces.},
