Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 230

Which two solutions are used to overcome a flapping link that causes a frequent label binding exchange between MPLS routers? (Choose two.)

Answer options

• A. Increase input queue on links to protect the session.
• B. Increase a hold-timer to protect the session.
• C. Increase a session delay to protect the session.
• D. Create link dampening on links to protect the session.
• E. Create targeted hellos to protect the session.

Correct answer: D, E

Explanation

The correct answers, D and E, are effective because link dampening reduces the impact of flapping by temporarily suppressing unstable links, while targeted hellos help maintain session stability by allowing for more controlled communication between routers. The other options do not specifically address the flapping issue or do not provide effective long-term solutions.
