Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 487

What is the purpose of the weight attribute in an EID-to-RLOC mapping?

Answer options

• A. It determines the administrative distance of LISP generated routes in the RIB.
• B. It indicates the load-balancing ratio between ETRs of the same priority.
• C. It indicates the preference for using LISP over native IP connectivity.
• D. It identifies the preferred RLOC address family.

Correct answer: B

Explanation

The weight attribute plays a crucial role in load balancing by determining the distribution of traffic among ETRs that share the same priority. Option A is incorrect because it relates to administrative distance, not load balancing. Option C is not accurate as it does not pertain to connectivity preferences, and option D misinterprets the weight attribute's function regarding address families.
