What is the role of Bidirectional Forwarding Detection (BFD)?

  • A to process destination host unreachable messages
  • B to detect routing loops
  • C to detect link failures
  • D to detect route flaps
Explanation

Bidirectional Forwarding Detection (BFD) rapidly detects failures in the forwarding path, including link or neighbor reachability failures, so dependent routing protocols can react quickly.
