What is the function of BFD?
BFD (Bidirectional Forwarding Detection) is a protocol designed for rapid fault detection in computer networks. Its primary function is to provide uniform and consistent failure detection across all types of media and network technologies. This means that BFD can be implemented over various network media—including Ethernet, MPLS, and SONET/SDH—ensuring consistent and fast detection of failures, enhancing network reliability and performance.

C is corerct
The correct answer is: C. It provides uniform failure detection regardless of media type. BFD (Bidirectional Forwarding Detection) is a protocol used for rapid failure detection in computer networks. One of its primary functions is to provide uniform and consistent failure detection regardless of the media type or technology being used in the network. BFD can be used with various network media types, including Ethernet, SONET/SDH, MPLS, and more. It ensures that failure detection is fast and consistent, making it a valuable tool for network reliability and fast convergence. Therefore, option C is the correct description of the function of BFD.
