The final bit. If set, the transmitting system is responding to a received BFD control
packet that had the poll (P) bit set.
Reserved bits. These bits must be zero on transmit and ignored on receipt.
Length of the BFD control packet, in bytes.
A unique, nonzero discriminator value generated by the transmitting system, used
to demultiplex multiple BFD sessions between the same pair of systems.
The discriminator received from the corresponding remote system. This field
reflects back the received value of my discriminator, or is zero if that value is
unknown.
This is the minimum interval, in microseconds, that the local system would like to
use when transmitting BFD control packets.
This is the minimum interval, in microseconds, between received BFD control
packets that this system is capable of supporting.
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.
