A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: Scoping Filters for Source-Specific Multicast
	Author(s)	: H. Holbrook
	Filename	: draft-holbrook-ssm-scoping-00.txt
	Pages		: 9

This document describes a method of providing scope-limited Source-
Specific Multicast (SSM) channels by filtering at boundary routers.  The filtering prevents SSM traffic from being forwarded through a scope
boundary.  Each administrative domain that wishes to enforce scoping can choose the sub-range of SSM channels that it wishes to scope -- no
globally-scoped address range is defined.  The method described here
does not require extending the current SSM range allocation to include a new 'scoped SSM' range.  The method described is primarily intended to provide scoping for IPv4 SSM channels, since IPv6 integrates multicast scoping into the basic addressing architecture.

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.
