Click the Exhibit button. 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.
extended LDP neighbor not established
B.
incorrect PE-CE interface configuration
C.
mismatched interface encapsulations
D.
mismatched virtual circuit ID values
