Multicast Routing Protocol support for P2MP
All multicast routing protocols support P2MP TE LSP. At ingress node, a multicast protocol must make a
mapping between the multicast traffic and the P2MP TE LSP with the configuration of static-join. At egress
node, the multicast protocol must conduct a special RPF check for the multicast packet which is received from
MPLS core and forward it to the customer facing interface. The RPF check is based on the configuration of
static-rpf. These multicast groups which are forwarded over the P2MP TE LSPs can be specified with the
static-rpf configuration in case of PIM-SSM.
Enabling Multicast Forwarding Over Tunnel Interface (at Ingress Node)
This configuration is used for allowing the forwarding of the multicast packet over the specified interface.
