Usage Guidelines

Usage Scenario

To enter the view of the specified BFD session before setting functional parameters for a created BFD session, run the bfd session-name command.

Prerequisites

A BFD session has been created using any of the following commands:

bfd bind peer-ip

bfd bind peer-ip default-ip

bfd bind peer-ip source-ip auto

bfd bind peer-ipv6

bfd bind peer-ipv6 source-ipv6 auto

Follow-up Procedure

After the BFD session view is displayed, you can perform the following operations:

Run the description command to configure a description for the BFD session.
Run the min-tx-interval command to set a desired minimum interval at which BFD packets are sent.
Run the min-rx-interval command to set a desired minimum interval at which BFD packets are received.
Run the detect-multiplier command to set a local detection multiplier for the BFD session.
Run the wtr command to set a WTR time for the BFD session.

Precautions

After the bfd session-name command is run, the BFD session view is displayed irrespective of whether the BFD session is Up.
If the BFD session is in the Down state and you run the bfd session-name command to enter the BFD session view and set functional parameters, the configurations can immediately take effect after being committed using the commit command.
You can run the undo bfd command to delete a specified BFD session.

# Enter the view of the BFD session named session.
