+         session is running in.
+
+         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

+        "The state of the running BFD session.
+
+         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
