 Technical Summary

   This document describes Multicast Router Discovery for both IPv4 and
   IPv6. For IPv4, Multicast Router Discovery is a direct translation
   of ICMP Router Discovery (RFC 1256); for IPv6 it is an extension to
   the Router Advertisement messages of the ICMP Neighbor Discovery

   Multicast Router Discovery performs two tasks. It allows devices
   such as IGMP-snooping switches to discover multicast routers in a
   protocol-independent way; without Multicast Router Discovery such
   devices have to snoop each type of routing protocol Hello to guess
   which ports point to multicast routers. In addition, it allows
   multicast routers to convey configuration parameters, such as the
   SSM group range, to all hosts on the subnet.

 Working Group Summary

   There was working group consensus on this document.
