RFC 7988 IR Tunnels in MVPN October 2016 As with any type of P2MP tree, each node of an IR P-tunnel holds "multicast state" for the P-tunnel. That is, each node knows the identity of its parent node on the tree, and each node knows the identities of its child nodes on the tree.
But to do this over a IPSEC tunnel, is yet to be seen. So unless you can define a tunnel interface, with ip_addres and PIM/IGMP multicast configurations, I highly doubt you can just send multicast traffic thru it ( ipsec/tunnel ) , without deploying a true native multicast architect underneath. NHRP is used similarly to the Address Resolution Protocol (ARP) on Ethernet, it provides the ability to map a tunnel IP address with a logical (Non-Broadcast Multi-Access (NBMA)) IP address; this allows mGRE to have dynamically set up tunnels without having to explicitly configure a mapping entry between each potential next-hop destination The multicast traffic is spread by multicast routers across the network from source to destinations. The multicast routers must find multicast sources on the network, send out copies of packets on a number of interfaces, avoid loops, connect interested destinations with accurate source and keep the flow of unsolicited packets to a minimum. P-Tunnel Signaling: This provides a way for PEs to tell other PEs what method it’s going to use for transporting C-Multicast traffic. Options could be P2MP RSVP-TE, P2MP mLDP,MP2MP mLDP, mGRE or Ingress replication. Network > Virtual Router > Multicast > Rendezvous Point. L3, VLAN, aggregate Ethernet, and tunnel.

Select Tunnel_to_SiteB. Click Edit. The Edit Tunnel dialog box appears. Select the Multicast Settings tab. Select the Enable multicast routing over the tunnel check box. In the Origination IP text box, type the IP address of the originator of the traffic. For this example, type 10.0.50.3.

A typical multicast on an Ethernet network, using the TCP/IP protocol, consists of two parts: Hardware/Ethernet multicast and IP Multicast. Later on I will talk about Mapping IP Multicast to Ethernet Multicast which is really what happens with multicasting on our Ethernet network using the TCP/IP protocol.
The multicast traffic is spread by multicast routers across the network from source to destinations. The multicast routers must find multicast sources on the network, send out copies of packets on a number of interfaces, avoid loops, connect interested destinations with accurate source and keep the flow of unsolicited packets to a minimum.
