• Final (F)—If set, the transmitting system is responding to a received BFD control packet that had the
Poll (P) bit set. If clear, the transmitting system is not responding to a Poll.
• Control Plane Independent(C)—If set, the transmitting system's BFD implementation does not share
fate with its control plane (BFD is implemented in the forwarding plane and can continue to function
through disruptions in the control plane.) If clear, the transmitting system's BFD implementation
shares fate with its control plane.
• Authentication Present (A)—If set, the Authentication Section is present and the session is to be
authenticated.
• Demand (D)—If set, Demand mode is active in the transmitting system (the system wishes to operate
in Demand mode, knows that the session is up in both directions, and is directing the remote system
to cease the periodic transmission of BFD Control packets). If clear, Demand mode is not active in
the transmitting system.
• Reserved (R)—This byte must be set to zero on transmit, and ignored on receipt.
• Detect Mult—Detection time multiplier.
• Length—Length of the BFD control packet, in bytes.
• My Discriminator—A unique, nonzero discriminator value generated by the transmitting system,
used to demultiplex multiple BFD sessions between the same pair of systems.
• Your Discriminator—It is the discriminator received from the remote system. This field reflects back
the received value of My Discriminator, or is 0 if that value is unknown.
• Desired Min TX Interval—This is the minimum interval, in microseconds, that the local system would
like to use when transmitting BFD control packets. The value zero is reserved.
• Required Min RX Interval—This is the minimum interval, in microseconds, between received BFD
control packets that this system is capable of supporting. If this value is zero, the transmitting system
does not want the remote system to send any periodic BFD control packets.
• Required Min Echo RX Interval—This is the minimum interval, in microseconds, between received
BFD echo packets that this system is capable of supporting. If this value is zero, the transmitting
system does not support the receipt of BFD echo packets.
• Auth Type—The authentication type in use, if the Authentication Present (A) bit is set.
• Auth Len—The length, in bytes, of the authentication section, including the Auth Type and Auth Len
fields.
