for example, if you configure the Desired Min TX Interval as 100 milleseconds,
Required Min Rx Interval as 300 milliseconds, and Detect Mult as 5 on Router A, and configure
the Desired Min TX Interval as 150 milleseconds, Required Min Rx Interval as 400 milliseconds,
and Detect Mult as 10 on Router B,
z
The actual transmitting interval on Router A is 300 milleseconds, that is, the greater value
between the minimum interval for transmitting BFD control packets on Router A and the
minimum interval for receiving BFD control packets on Router B.
z
The actual transmitting interval on Router B is 300 milleseconds, that is, the greater value
between the minimum interval for transmitting BFD control packets on Router B and the
minimum interval for receiving BFD control packets on Router A.
z
The actual detection time on Router A is 3000 milliseconds, that is, 10 × 300 milliseconds.
z
The actual detection time on Router B is 2000 milliseconds, that is, 5 × 400 milleseconds.
Enabling Trap
When the trap function is enabled on the BFD module, the module will generate trap messages
at the notifications level to report the important events of the module. The generated trap
messages are sent to the device's information center, which determines the output rules for the
trap messages, namely, whether to output the trap messages and the output destinations).
