The concept of Internet Group Management Protocol (IGMP) and
Multicast Listener Discovery (MLD) snooping requires the ability to
identify the location of multicast routers.  Since snooping is not
standardized, there are many mechanisms in use to identify the
multicast routers.  However, this can lead to interoperability issues
between multicast routers and snooping switches from different
vendors.

This document introduces a general mechanism that allows for the
discovery of multicast routers.  This new mechanism, Multicast Router
Discovery (MRD), introduces a standardized means of identifying
multicast routers without a dependency on particular multicast
routing protocols.

This document is a product of the Multicast & Anycast Group Membership
Working Group of the IETF.

This is now a Proposed Standard Protocol.

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
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.

This announcement is sent to the IETF list and the RFC-DIST list.
