	Title		: Encapsulating MPLS in IP or GRE

In various applications of MPLS, label stacks with multiple entries
are used.  In some cases, it is possible to replace the top label of
the stack with an IP-based encapsulation, thereby enabling the
application to run over networks which do not have MPLS enabled in
their core routers.  This draft specifies two IP-based
encapsulations, MPLS-in-IP, and MPLS-in-GRE.  Each of these is
applicable in some circumstances.

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.
