Bidirectional Forwarding Detection (BFD) verifies bidirectional connectivity
between forwarding engines, which can be a single hop or multiple hops away.
The protocol works over any underlying transmission mechanism and
protocol layer with a wide range of detection times, especially in scenarios
where fast failure detection is required in data plane level for multiple
concurrent sessions.
Use the following commands to configure Bidirectional Forwarding Detection
commands (BFD).
feature bfd
Use this command to enable BFD on the router. Use the no form of the
command to disable BFD and clear any dynamic state.
Syntax

Default Configuration
BFD is not enabled by default.

User Guidelines
BFD supports fast detection of forwarding failures on a routing interface.
BFD provides an advantage for forwarding plane failure detection over that
provided by the individual protocols, each having different hello protocol
timers and detection periods.
