JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 65

Which two statements are correct when using LDP? (Choose two.)

Answer options

• A. The inet.3 table will contain a full mesh of label-switched paths to other LDP-enabled routers.
• B. LDP label-switched paths are created by configuring LDP on at least one physical router interface.
• C. LDP label-switched paths are created by configuring LDP on the loopback interface.
• D. The inet.3 table will contain only the paths explicitly defined.

Correct answer: A, C

Explanation

Option A is correct because the inet.3 table indeed reflects a full mesh of paths to other LDP-enabled routers. Option C is also correct as configuring LDP on the loopback interface can facilitate label-switched paths. Options B and D are incorrect because LDP does not require configuration on a physical interface alone to create paths, nor does the inet.3 table limit its entries to explicitly defined paths.
