Explanation

BGP session flaps are often caused by connectivity or path failures, and enabling Bidirectional Forwarding Detection (BFD) helps mitigate this issue. BFD detects link failures faster than the default BGP timers, allowing the session to recover quickly and reducing the frequency and impact of BGP session flapping.
