You are configuring an LDP Layer 2 circuit on a Juniper PE. The remote PE is at 192.0.2.2. You have configured the logical interface ge-0/0/1.0 with family l2circuit. Which additional configuration is required to establish the circuit?

set protocols mpls interface ge-0/0/1.0

set protocols l2circuit neighbor 192.0.2.2 interface ge-0/0/1.0 virtual-circuit-id 100

set protocols ldp interface ge-0/0/1.0

set interfaces ge-0/0/1 unit 0 family mpls

In an LDP Layer 2 circuit, what is the role of the virtual circuit (VC) label?

It is the transport label used to forward packets across the MPLS backbone

It is assigned by the customer edge router to identify the attachment circuit

It identifies the specific Layer 2 circuit within the MPLS tunnel

It is used to encrypt the Layer 2 frames before transmission

A service provider is designing a point-to-point Ethernet service. They are considering using an LDP Layer 2 circuit. Which statement correctly describes a key characteristic of this solution?

The service requires a full mesh of LDP sessions between all PEs.

The service is point-to-point and uses LDP to signal the virtual circuit label.

The service is multipoint and uses LDP to signal the virtual circuit label.

The service requires RSVP to signal the virtual circuit label.
