The PIM Reverse Path Forwarding (RPF) Vector TLV defined in RFC 5496
can be included in a PIM Join Attribute such that the RPF neighbor is
selected based on the unicast reachability of the RPF Vector instead
of the source or Rendezvous Point associated with the multicast tree.
This document defines a new RPF Vector Attribute type such that an
explicit RPF neighbor list can be encoded in the PIM Join Attribute,
thus bypassing the unicast route lookup.
This document is a product of the Protocols for IP Multicast Working Group of the IETF.
This is now a Proposed Standard.

for improvements. Please refer to the current edition of the Official
