Question 25

Click the Exhibit button.

Referring to the outputs shown in the exhibit, which two statements are correct about the IS-IS adjacency? (Choose two.)

    Correct Answer: A, D

    In the IS-IS protocol, the circuit type indicates the levels at which the router is participating. Circuit type 1 means Level 1 only, circuit type 2 means Level 2 only, and circuit type 3 means both Level 1 and Level 2. From the output shown, R1 has a circuit type of 2, indicating it is configured to participate in Level 2 only. R2 has a circuit type of 3, indicating it is configured to participate in both Level 1 and Level 2. Therefore, the correct statements are that R1 is configured to participate in Level 2 only, and R2 is configured to participate in both Level 1 and Level 2.

Discussion
TakigamaOptions: BC

Circuit type identifies the router you are running the command ON, not the connected router. In the diagram, R1 says Circuit type 2 - Therefore R1 (not R2) is level 2 only In the diagram, R2 says Circuit type 3 - Therefore R2 (and not R1) is Level 1 and level 2 Other comments here say similar but say it wrong or have the wrong answer. The circuit type in "show isis adjacency extensive" output is always related to the router you ran the command on!

R1 (and not R1) has circuit type 2 which means that R2 is configured to participate in Level 2 only, answer D is correct. R2 (and not R1) has circuit type 3 which means that R1 is configured to participate in both Level 1 and Level 2, answer A is correct.
