The primary mode which the BFD session runs in is known as Asynchronous mode. In this mode, the systems periodically send BFD Control packets to one another, and if a number of those packets in a row are not received by the other system, the session is declared to be down. The second mode is known as Demand mode. In this mode, it is assumed that each system has an independent way of verifying that it has connectivity to the other system. Once a BFD session is established, the systems stop sending BFD Control packets, except when either system feels the need to verify connectivity explicitly, in which case a short sequence of BFD Control packets is sent, and then the protocol quiesces. An adjunct to both modes is the Echo function. When the Echo function is active, a stream of BFD Echo packets is transmitted in such a way as to have the other system loop them back through its forwarding path. If a number of packets of the echoed data stream are not received, the session is declared to be down. The Echo function may be used with either Asynchronous or Demand modes. The 'asynchModeWOEchoFun' indicates this BFD session operates in the Asynchronous mode, and doesn't support the Echo Function. The 'demandModeWOEchoFunction' indicates this BFD session operates in the Demand mode, and doesn't support the Echo Function. The 'asyncModeWEchoFun' indicates this BFD session operates in the Asynchronous mode, and also supports the Echo Function. The 'demandModeWEchoFunction' indicates this BFD session operates in the Demand mode, and also supports the Echo Function."

There are three states through which a session normally proceeds, two for establishing a session (Init and Up) and one for tearing down a session (Down.) This allows a three-way handshake for both session establishment and session teardown (assuring that both systems are aware of all session state changes.) A fourth state (AdminDown) exists so that a session can be administratively put down indefinitely. The Down state means that the session is down (or has just been created.) A session remains in Down state until the remote system indicates that it agrees that the session is down by sending a BFD Control packet with the State field set to anything other than Up. If that packet signals Down state, the session advances to Init state; if that packet signals Init state, the session advances to Up state. Init state means that the remote system is 0communicating, and the local system desires to bring the session up, but the remote system does not yet realize it. A session will remain in Init state until either a BFD Control Packet is received that is signaling Init or Up state (in which case the session advances to Up state) or until the detection time expires, meaning that communication with the remote system has been lost (in which case the session advances to Down state.) Up state means that the BFD session has successfully been established, and implies that connectivity between the systems is working. The session will remain in the Up state until either connectivity fails, or the session is taken down administratively. If either the remote system signals Down state, or the detection time expires, the session advances to Down state. AdminDown state means that the session is being held administratively down. This causes the remote system to enter Down state, and remain there until the local system exits AdminDown state."
