Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 193

Which condition must be met for TI-LFA to protect LDP traffic?

Answer options

• A. For single-segment protection, the PQ node must be LDP and SR-capable.
• B. The protected destination must have an associated LDP label and prefix-SID.
• C. The point of local repair must be LDP-capable.
• D. For double-segment protection, the P and Q nodes must be SR-capable.

Correct answer: D

Explanation

The correct answer is D because double-segment protection specifically requires both P and Q nodes to support Segment Routing (SR) for effective traffic management. Options A, B, and C, while relevant to other aspects of traffic protection, do not address the specific requirements for double-segment protection under TI-LFA.
