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
Why B and not A? I think both A and B are correct. Do they mean inter-provider VPLS (“a Layer 2 VPN service between service provider networks”)? If so, only option B is correct.

probably the question asks about betweem SP which is inter-are vpn. thru bgp it can be easily acheived. yet ldp could be an option but this is not a standrd deployment for inter-as l2 vpn
