164
• 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: 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.
