This document specifies a mechanism to avoid blackholing of IP 
Multicast traffic due to the disruption of multicast tree during the 
time when the RPF neighbor is yet to become the PIM neighbor. Such 
scenario is possible during the topology change (e.g. link UP) in an 
IP network that employs PIM-SM (or SSM) as the multicast routing 
protocol and a unicast routing protocol (including static routing).
