Title : Bidirectional RSVP-TE Tunnel

Through the binding of two unidirectional RSVP-TE tunnels established
between a pair of LSRs destined to each other, a bidirectional RSVP-
TE tunnel is formed. Like GRE tunnel, the bidirectional RSVP-TE
tunnel can be used to establish L3VPN with virtual router or policy
routing technology. In contrast to BGP/MPLS VPN defined in
[RFC2547bis], multicast is easier to be implemented and multicast
traffics can travel in RSVP-TE tunnel with such L3VPN. This L3VPN
fully inherits the property of RSVP-TE, such as TE, QoS and fast
convergence features. In addition, the bidirectional RSVP-TE tunnel
has many other purposes, such as interconnection of two separate
routing domains through a RSVP-TE tunnel and implementing LDP over TE.

In the body type:

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.
