This document specifies Version 3 of the Internet Group Management
Protocol, IGMPv3. IGMP is the protocol used by IPv4 systems to report
their IP multicast group memberships to neighboring multicast routers.
Version 3 of IGMP adds support for 'source filtering', that is, the
ability for a system to report interest in receiving packets *only* from
specific source addresses, or from *all but* specific source addresses,
sent to a particular multicast address. That information may be used by
multicast routing protocols to avoid delivering multicast packets from
specific sources to networks where there are no interested receivers.

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
