Title : Multicast Router Discovery

The concept of IGMP snooping requires the ability to identify the
location of multicast routers. Since IGMP (and MLD) snooping is not
standardized, there are many mechanisms in use to identify the
multicast routers. However, this scenario can lead to
interoperability issues between multicast routers and layer-2
switches from different vendors.
This document introduces a general mechanism that allows for the
discovery of multicast routers. By introducing these new messages,
snooping devices have a uniform means of identifying multicast
routers without dependency on particular routing protocols. These
messages may also be used to convey configuration parameters to all
systems on a network. In addition, other devices that may need to
discover multicast routers can utilize these messages.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
