Title : Interworking between IP VPN and shared backbone

This draft introduces an interworking function between shared backbone
multicast domain and VPN multicast domain. The architecture that
follows is similar to Multicast Border Router functionality, however the
mapping is defined not as a mapping between two different multicast
protocols, but two different multicast topologies the under assumption
that the shared backbone multicast topology will be shared between VPNs
for carrying the traffic. The main assumption made in this draft is that
multicast packets are replicated on PE device (router) for scalability
and performance reasons. However, it is possible to extend the solution
and replicate packets on CE devices. The proposed mapping of addresses
to topology solves the issue of scalability of multicast addresses to
state knowledge in the core. This draft also identifies three types of
multicast capabilities for the core.

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.
