• Question 124:

  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. mismatched virtual circuit ID values

  B. mismatched interface encapsulations

  C. incorrect PE-CE interface configuration

  D. extended LDP neighbor not established

  Correct Answer: B

  A. ping 10.10.1.1

  B. ping 10.10.1.1 table customer-a

  C. ping 10.10.1.1 instance customer-a

  D. ping 10.10.1.1 routing-instance customer-a

  Correct Answer: D

• Question 127:

  Click the Exhibit button.

  

  You are configuring a new PE router in your Layer 3 VPN. A remote PE router is using the configuration shown in the exhibit. Which configuration is needed to receive customer-vpn routes from the remote PE?

  C. Option C

  D. Option D

  Correct Answer: C

• Question 128:

  Click the Exhibit button.

  

  Based on the output in the exhibit, which statement is correct?

  A. R4 has been configured with an IS-IS export policy and is announcing external routing information.

  B. R3 and R4 have an adjacency at both level 1 and level 2.

  C. R3 has been configured so that it is not used for transit traffic.

  D. R3 and R4 are both attached to other IS-IS areas.

  Correct Answer: C

• Question 129:

  What is a limitation of LDP?

  A. Traffic must follow explicitly configured paths.

  B. It requires a full mesh of LSPs throughout the network.

  C. It requires a traffic engineering database (TED).

  D. It does not support traffic engineering.

  Correct Answer: D

• Question 130:

  Click the Exhibit button.
