Technical Summary
 The concept of Internet Group Membership 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.
Working Group Summary
The working group strongly supports the advancement of the
Multicast Router Discovery draft.
