Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 72

A network team has failed to implement IS-IS multitopology. What is the reason for it?

Answer options

• A. The routing process supported Level 1 only
• B. The router did not support VRFs
• C. The routing process did not support extended metrics
• D. The router did not have Cisco Discovery Protocol and Cisco Express Forwarding disabled

Correct answer: C

Explanation

The correct answer is C because IS-IS multitopology requires support for extended metrics to function properly. Options A and B are incorrect as they reference limitations that do not directly impact multitopology implementation. Option D addresses features that are not prerequisites for IS-IS multitopology.
