Command Parameters
- enable
- Enable BFD on a loopback.
- interval
- Specifies the transmit interval in
milliseconds. The default is 200 ms. The minimum value for the transmit interval
is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value
for the transmit interval. You can configure the remaining BFD sessions with a
transmit interval that is greater than or equal to the 200 ms default value.
- min_rx
- Specifies the receive interval in
milliseconds. The default is 200 ms. The minimum value for the receive interval is
100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for
the receive interval. You can configure the remaining BFD sessions with a receive
interval that is greater than or equal to the 200 ms default value.
- multiplier
- Specifies the multiplier used to
calculate the amount of time BFD waits before it declares a receive timeout. The
default is 3. If you configure the transmit interval or the receive interval as
100 ms, you must configure a value of 4 or greater for the multiplier.
Default
The default is disabled.
