Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 134

After implementing MPLS protocol for multiple VRFs on a single Cisco device, the engineer notices all VRFs on the router still do not have the LDP session protection feature enabled. Which configuration must the engineer apply to enable the LDP session protection feature for LDP neighbors within each VRF?

Answer options

• A. Configure LDP session protection globally on the device only.
• B. Configure LDP session protection within the individual VRFs.
• C. Configure LDP session authentication on the device to enable LDP session protection on each VRF automatically.
• D. Configure LDP session protection globally on the device and on each neighbor that requires session protection.

Correct answer: A

Explanation

The correct answer is A because enabling LDP session protection globally on the device is sufficient for all VRFs. Options B and C are incorrect as they suggest configuring session protection at the VRF level or assuming automatic configuration, which is not the case. Option D, while it mentions global configuration, adds unnecessary steps by requiring individual neighbor configuration.
