Technical Summary On a multi-access network, one of the PIM-SM routers is elected as a Designated Router. One of the responsibilities of the Designated Router is to track local multicast listeners and forward data to these listeners if the group is operating in PIM-SM. This document specifies a modification to the PIM-SM protocol that allows more than one of the PIM-SM routers to take on this responsibility so that the forwarding load can be distributed among multiple routers. Working Group Summary There was very thorough review by the WG; there were many comments and all were addressed. This document has been in process for several years, and was sent to the IESG for publication twice (with a 4-year difference) due to concerns by the AD. Document Quality There is one implementation of the specification. Personnel Mike McBride is the document shepherd and Alvaro Retana is the responsible Area Director.
