Both PE1 and PE2 show the circuit state as VM - - vlan id mismatch. Referring to the exhibit, which action will solve this problem?
Options
- AConfigure interfaces PE1:ge-1/0/1.5 and PE2:ge-1/1/1.6 with the output-vlan-map pop parameter.
- BConfigure interfaces PE1:ge-1/0/1.5 or PE2:ge-1/1/1.6 with the output-vlan-map swap parameter.
- CConfigure the LDP Layer 2 circuit with the no-control-word command on PE1 and PE2.
- DConfigure interfaces PE1:ge-1/0/1.5 and PE2:ge-1/1/1.6 with the output-vlan-map swap
