A network engineer must select a high availability feature for their data center. The solution must ensure network resilience, reduce network instability for Layer 3 routing protocols, and meet these requirements:
• The device must notify its neighbors when the control plane is undergoing a restart.
• The solution must suppress routing flaps in case of stateful switchovers.
Which solution must be implemented?
Non-Stop Forwarding (NSF) provides a solution for ensuring network resilience by allowing the data plane to continue forwarding packets while the control plane restarts. It also helps in reducing network instability for Layer 3 routing protocols by maintaining routing information and suppressing routing flaps during stateful switchovers. Additionally, NSF meets the requirement of notifying neighbors when the control plane is undergoing a restart, which is crucial for maintaining stable and resilient network operations.
Correct, Non-Stop Forwarding (NSF) provides a solution for network resilience, reduced Layer 3 routing instability, control plane restart notification, and stateful switchover flap suppression.
