Run the command set protocols ospf interface bfd to enable Bidirectional Forwarding Detection (BFD) on the interface. It allows OSPF to listen for BFD events on peers created on the interface. Every time a new neighbor is found a BFD peer is created to monitor the link status for fast convergence. The three BFD timers can be configured to the desired value.

The detect-multiplier configures the detection multiplier to determine packet loss. The remote transmission interval will be multiplied by this value to determine the connection loss detection timer. The default value is 3.

The min-receive-interval configures the minimum interval that the system is capable of receiving control packets. The default value is 300 milliseconds.

The min-transmit-interval configures the minimum transmission interval that the system wants to use to send BFD control packets. The default value is 300ms.

Run the command delete protocols ospf interface bfd to remove this configuration.

Command Syntax

set protocols ospf interface <vlan-interface> bfd [detect-multiplier<2-255>] [min-receive-interval <50-60000>] [min-transmit-interval <50-60000>]

delete protocols ospf interface <vlan-interface> bfd [detect-multiplier <2-255>] [min-receive-interval <50-60000>] [min-transmit-interval <50-60000>]

Parameter

Parameter	Description
interface <vlan-interface>	Specifies the name of the interface.
detect-multiplier <2-255>	Specifies the BFD detection multiplier to detect packet loss. The value ranges from 2 to 255, the default value is 3.
min-receive-interval <50-60000>	Specifies the BFD minimum interval that the system is capable of receiving control packets. The default value is 300 milliseconds.
min-transmit-interval <50-60000>	Specifies the The minimum transmission interval that this system wants to use to send BFD control packets. The default value is 300ms.

Example

Configure the BFD min-receive-interval to 100.
