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.
