Title : MT Tunnel Discovery and RPF check

Multicast Tunnels are built between Provider Edge (PE) routers
to allow multicast communication between different site's of a VPN.
The MT tunnel has a destination MDT group address that is unique
to the VPN. All routers that act as PE's and are configured for a
specific VPN join the VPN MDT multicast group in the backbone of
the provider network to be able to receive each others packets. Each
router is also a sender to the MDT group. How the forwarding of
the MDT packets is achieved is depending on the PIM mode of the MDT
group. This can be either PIM-Bidir, PIM-SM or PIM SSM. The proposal
in this document is related specifically to PIM SSM mode.

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.
