This command configures the BFD session parameters for all available interfaces on the device (Global Config mode) or IP interface (Interface Config mode). It overwrites any BFD configurations present on individual interfaces (Global Config mode) or globally configured BFD session parameters (Interface Config).

| Parameter | Description |
|---|---|
| transmit-interval | The desired minimum transmit interval, which is the minimum interval that the user wants to use while transmitting BFD control packets. It is represented in milliseconds. Its range is 100 ms to 1000 ms (with a change granularity of 100) a with default value of 100 ms. |
| minimum-receive-interval | The required minimum receive interval, which is the minimum interval at which the system can receive BFD control packets. It is represented in milliseconds. Its range is 100 ms to 1000 ms (with a change granularity of 100) with a default value of 100 ms. |
| detection-time-multiplier | The number of BFD control packets that must be missed in a row to declare a session down. Its range is 1 to 50 with default value of 3. |
Example: The following steps configure BFD session parameters on the device, in Privileged EXEC mode.
(Router)# configure (Router) (Config)# bfd interval 100 min_rx 200 multiplier 5 (Router) (Config)# exit
Example: The following steps configure BFD session parameters on an interface (for example, 1/0/1).
(Router) (Config)# interface 1/0/1 (Router) (Interface 1/0/1)# bfd interval 100 min_rx 200 multiplier 5 (Router) (Interface 1/0/1)# exit
