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

PPVPN

WHY IS IT TARGETED AT THIS WG

PPVPN WG charter specifies explicitly to consider BGP-VPN services, more 
specifically based on RFC 2547. In addition WG charter includes Layer 2 
Network Based VPN services. The ID discussed here presents methods to 
provide both Layer 2 and Layer 3 VPN services using RFC 2547.

JUSTIFICATION

Layer 2 VPN services are gaining popularity in emerging metro services 
infrastructure. Concepts introduced in RFC 2547 is becoming a popular method 
in  providing Layer 3 VPN services. As Layer 2 VPN becomes available, the 
same providers may be required to provide both Layer 2 and Layer 3 VPN 
services. Ability to use same control protocol to provide two classes of VPN 
not only provide flexibility but also allow investment protection and 
migration from one class to another or co-offering.
