Description
This feature provides a way for PIM source-specific
multicast (SSM) to resolve Vector Type Length (TLV) for multicast
in a seamless Multiprotocol Label Switching (MPLS) networks. In other
words, it enables PIM to build multicast trees through an MPLS core. rpf-vector implements RFC 5496, Reverse Path Forwarding (RPF)
Vector TLV .
When rpf-vector is enabled on an edge router that
sends PIM join messages into the core, the join message includes a
vector specifying the IP address of the next edge router along the
path to the root of the multicast distribution tree (MDT). The core
routers can then process the join message by sending it towards the
specified edge router (i.e., toward the Vector). The address of the
edge router serves as the RPF vector in the PIM join message so routers
in the core can resolve the next-hop towards the source without the
need for BGP in the core.
Only the IPv4 address family is supported.
