What is BFD echo packet?

BFD is a simple hello/echo protocol used to provide millisecond failure detection for other protocols such as IGPs, BGP, and a few others. BFD allows those protocols to continue with their intended purpose, while offloading the responsibility of link failure detection.

What is the default sending interval of BFD packets?

The default interval is 500 milliseconds. Zero indicates that the local end is not interested in receiving echo packets from the peer.

How does BFD protocol work?

BFD provides a low-overhead, short-duration method of detecting failures in the forwarding path between two adjacent routers, including the interfaces, data links, and forwarding planes. BFD is a detection protocol that you enable at the interface and routing protocol levels.
