Parameters

None

Default Level

2: Configuration level

Usage Guidelines

After the process-interface-status command associates a BFD session with the status of an interface bound to the BFD session, a local device does not instruct the interface protocol to go down after the device receives an admindown packet. To enable an immediate notification, run the receiving-admindown trigger if-down command.

Prerequisites

The BFD session status has been associated with the status of the interface bound to the BFD session using the process-interface-status command.

Precautions

This command is supported in both BFD authentication and non-authentication scenarios.
This command takes effect only on multicast BFD.
If the trigger if-down delay command is run, the local device can instruct the interface protocol to go down immediately after receiving an admindown packet.

Example

# Enable the local device to instruct the interface protocol to go down immediately after receiving an admindown packet.
