An LDP Layer 2 circuit between PE1 and PE2 is not passing traffic. Both PE1 and PE2 show the circuit state as
VM – – vlan id mismatch.
Referring to the exhibit, which action will solve this problem?

A.
Configure interfaces PE1:ge-1/0/1.5 and PE2:ge-1/1/1.6 with the output-vlan-map pop parameter.

B.
Configure interfaces PE1:ge-1/0/1.5 or PE2:ge-1/1/1.6 with the output-vlan-map swap parameter.

C.
Configure the LDP Layer 2 circuit with the no-control-word command on PE1 and PE2.

D.
Configure interfaces PE1:ge-1/0/1.5 and PE2:ge-1/1/1.6 with the output-vlan-map swap parameter.

Explanation:
The output-vlan-map swap parameter specifies the VLAN rewrite operation to replace a VLAN tag. The outer
VLAN tag of the frame is overwritten with the user-specified VLAN tag information. We do this on both
interfaces.
