You are responding to an RFP for a new MPLS VPN implementation. The solution must use LDP for signaling and support Layer 2 connectivity without using BGP The solution must be scalable and support multiple VPN connections over a single MPLS LSP The customer wants to maintain all routing for their Private network

In this scenario, which solution do you propose?

A.
circuit cross-connect
Answers
A.
circuit cross-connect
B.
BGP Layer 2 VPN
Answers
B.
BGP Layer 2 VPN
C.
LDP Layer 2 circuit
Answers
C.
LDP Layer 2 circuit
D.
translational cross-connect
Answers
D.
translational cross-connect
Suggested answer: C

Explanation:

AToM (Any Transport over MPLS) is a framework that supports various Layer 2 transport types over an MPLS network core. One of the transport types supported by AToM is LDP Layer 2 circuit, which is a point-to-point Layer 2 connection that uses LDP for signaling and MPLS for forwarding. LDP Layer 2 circuit can support Layer 2 connectivity without using BGP and can be scalable and efficient by using a single MPLS LSP for multiple VPN connections. The customer can maintain all routing for their private network by using their own CE switches.
