On a multi-access network, one of the PIM-SM (PIM Sparse Mode)
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.

This document is a product of the Protocols for IP Multicast Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
