Question
What is the failure detection time with BFD?
A. 3 seconds
B. less than a second
C. 2 seconds
D. 1 second
Answer
B. less than a second
Explanation
The failure detection time with BFD is less than a second. BFD (Bidirectional Forwarding Detection) is a protocol that provides fast failure detection between two devices. It operates by sending periodic hello packets between the devices, and if a hello packet is not received within a configurable interval, the connection is considered down. The default BFD interval is 50 milliseconds, which means that a failure can be detected in less than a second.
