NAME of I-D:

http://search.ietf.org/internet-drafts/draft-tsenevir-l2vpn-pmesh-00.txt

SUMMARY:

This I-D  Discuss methods to achieve proper forwarding of Broadcast,
Multicast and Unknown traffic over a set of partial mesh tunnels. In
addition, the methods presented in this document may be used to achieve loop
free topology  Methods presented in this ID helps to develop many-to-many
Layer 2 VPN solutions using set of partial meshed tunnels.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK

The ID presented fits in to the PPVPN WG and/or CCAMP WG. 

WHY IS IT TARGETED AT THIS WG(s)

Sub-IP and IP tunnels are becoming a popular method in carrying data
transparently over the provider or the core network.

Use of such tunnels are key component of PPVPN infrastructure. On the other
hand CCAMP WG charter includes defining common control and measurement
plane. Hence optimal use of tunnels is an integral part of the control
infrastructure.


JUSTIFICATION

Increasing number of service providers are offering Ethernet services to the
customer. In the core of the network IP or Sub-IP technologies are used. In
general, Ethernet services provided to customers are VPN service having
multi-points of service access (as opposed to point-to-point).

Requirement to use fully meshed networks seriously affects the scalability
of Layer 2 NBVPN. The methods presented in this document facilitate service
providers to offer scalable Layer 2 VPN solutions.
