Abstract
Embodiments of the invention are directed to establishing a PIM tree to a source that is reachable over a unicast tunnel in a packet switched network. Advantageously, a Reverse Path Forwarding (RPF) Vector TLV to establish a PIM tree may be used in cases where there is an absence of source reachability in the core of a network.
