You are asked to design a Layer 2 VPN service between service provider networks that needs
Ethernet transport capabilities. The VPN should support two or three endpoints. Which Layer 2
VPN technology should you propose?
A.
LDP-signaled VPLS
B.
BGP-signaled VPLS, using the RFC 4448 Layer 2 frame format
C.
LDP Layer 2 circuit, using the RFC 4448 Layer 2 frame format
D.
BGP Layer 2 VPN
Explanation:
2 or 3 endpoints = VPLS
RFC 4448 = Encapsulation Methods for Transport of Ethernet over MPLS Networks
