The rip bfd command sets BFD session parameters on the specified interface.
The undo rip bfd command restores BFD session parameters set on the specified interface.
By default, BFD session parameters are the default values.
rip bfd { min-rx-interval min-receive-value | min-tx-interval min-transmit-value | detect-multiplier detect-multiplier-value } *
undo rip bfd { min-rx-interval [ min-receive-value ] | min-tx-interval [ min-transmit-value ] | detect-multiplier [ detect-multiplier-value ] } *
| Parameter | Description | Value |
|---|---|---|
| min-rx-interval min-receive-value | Specifies the minimum interval at which BFD packets are received from the remote device. |
The value is an integer ranging from 100 to 1000, in milliseconds. The default value is 1000. |
| min-tx-interval min-transmit-value | Specifies the minimum interval at which BFD packets are sent to the remote device. |
The value is an integer ranging from 100 to 1000, in milliseconds. The default value is 1000. |
| detect-multiplier detect-multiplier-value | Specifies the local detection multiplier. | The value is an integer ranging from 3 to 50. The default value is 3. |

Usage Scenario
The min-receive-value value is obtained after the local min-rx-interval value and a neighbor's min-tx-interval value are negotiated. For detailed negotiation policies, see bfd all-interfaces (RIP). If the FW does not receive BFD packets from the neighbor at the interval of min-receive-value x detect-multiplier-value, the neighbor will go Down.
Prerequisites
Enable BFD globally and run the rip bfd enable command before establishing a BFD session.
Precautions
BFD session parameters configured in a RIP process take effect only after BFD is enabled on the interface.
The BFD priority configured on an interface is higher than the BFD priority configured in a RIP process. If BFD session parameters are configured on an interface, establish a BFD session based on the configured parameters.
# Enable BFD on GigabitEthernet 0/0/1 and set the minimum sending interval to 600 ms and local detection multiplier to 4.
