JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 52

You have configured the router with an IS-IS interface metric of 2048. However, the IS-IS interface metric of 63 is being applied for the interface of this router.
What must you do to enable the larger metric value?

Answer options

• A. Enable wide metrics.
• B. Disable narrow metrics.
• C. Restart the IS-IS protocol.
• D. Enable level 1 IS-IS routing.

Correct answer: B

Explanation

To utilize the larger metric value of 2048, you need to disable narrow metrics, which restricts the metric range. The other options do not directly address the issue of metric size; enabling wide metrics (option A) is not applicable when narrow metrics are in use, restarting the IS-IS protocol (option C) won't change the metric configuration, and enabling level 1 IS-IS routing (option D) does not affect the metric values.
