PIM Designated Router Load Balancing
RFC 8775, “PIM Designated Router Load Balancing”, is a Proposed Standard document published in April 2020 by Y. Cai, H. Ou, S. Vallepalli, M. Mishra, S. Venaas, A. Green. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
