Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 54

A router RP is configured to perform MPLS LDP graceful restart.
Which three steps are included when the RP sends an LDP initialization message to a neighbor to establish an LDP session? (Choose three.)

Answer options

• A. Learn from Neighbor (N) flag, set to 1
• B. Recovery Time field
• C. Type-9 LSA
• D. Reconnect Timeout field
• E. Graceful restart capability in OPEN message
• F. Learn from Network (L) flag, set to 1

Correct answer: B, D, F

Explanation

The correct steps include the Recovery Time field, Reconnect Timeout field, and Learn from Network (L) flag, which are essential for negotiating the parameters of the LDP session during a graceful restart. The other options, while related to LDP, do not specifically pertain to the initialization process in this context.
