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?
mismatched virtual circuit ID values
mismatched interface encapsulations
incorrect PE-CE interface configuration
extended LDP neighbor not established
