Abstract
A network device for performing bidirectional forwarding detection (BFD) includes a processor that receives packets from a peer; a session state machine that manages a session with the peer; a receive module that determines whether the packet indicates no change to the session; and a transmit module. The transmit module transmits BFD packets at an interval determined by the session state machine and transmits a session change packet in response to a configuration update by the session state machine.
