Title : Encapsulating MPLS in IPsec
Author(s) : R. Aggarwal
Filename : draft-raggarwa-mpls-ipsec-00.txt
Pages : 8
Date : 2004-1-27
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. MPLS-in-IP and MPLS-in-GRE encapsulations have
already been specified by the MPLS WG. In some cases, in addition to
IP and GRE tunnels, it may be desirable to use IPsec for transporting
MPLS packets securely over non-MPLS networks, using standard IPsec
authentication and/or encryption functions. This draft describes
procedures for encapsulating MPLS packets in IPsec.

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.
