Customer A is complaining that CE1 and CE2 cannot form an OSPF adjacency across your LDP
Layer 2 circuit. The physical topology of the network is CE1-PE1-P-PE2-CE2. PE1’s loopback is
192.168.5.1, P’s loopback is 192.168.6.1, and PE2’s loopback is 192.168.7.1.
Referring to the output in the exhibit, what is the problem?

A.
mismatched virtual circuit ID values
B.
mismatched interface encapsulations
C.
incorrect PE-CE interface configuration
D.
extended LDP neighbor not established
Explanation:
l2circuit {
…neighbor 10.245.14.179 { # This points to the loopback of the remote PE neighbor.
…..interface fe-1/1/0.600 { # Here you include the local CE-facing interface.
……..virtual-circuit-id 5 { # Be sure this ID matches the ID of your PE neighbor.
