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.

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 corresponding 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
