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 192.168.7.1Referring 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
