Dear members of the l3vpn distribution list,

I want to introduce a new method of implementing MVPN in 2547bis VPN with pseudo wires technology. http://tools.ietf.org/wg/l3vpn/draft-xu-l3vpn-2547bis-mcast-01.txt

It belongs to ingress replication methods, and as there is not special requirement on P routers, the scalability of this MVPN solution is good. In addition, the multicast traffic in MVPN could be distributed accurately to the necessary PEs.

The main difference with "draft-ietf-l3vpn-2547bis-mcast-00" lies in the demultiplexor of tunnel between each pair of the PEs within the same MVPN. That is to say, in my implementation of MVPN, the VC label as demultiplexor not only says to which specific MVPN a packet belongs, but also identifies the ingress PE. For this reason, there is no need to carry ingress PE's address in multicast traffic with a special encapsulation such as GRE or 
MPLS-in-IP.

Any comment from you will be expected.
