Usage Guidelines

Usage Scenario

When creating a static BFD session, run the discriminator command to set local and remote discriminators. Otherwise, the static BFD session cannot be set up. The local and remote discriminators differentiate BFD sessions between two systems.

Precautions

Only static BFD sessions require settings of local and remote discriminators.
The local discriminator of the local system and the remote discriminator of the remote system must be the same. If the local discriminator of the local system and the remote discriminator of the remote system are different, a static BFD session cannot be set up.
After the local and remote discriminators of a static BFD session are configured, the local and remote discriminators cannot be modified. To modify the local and remote discriminators of a static BFD session, delete the BFD session and reconfigure the local and remote discriminators.

Example

# Set the local discriminator of a BFD session to 80 and the remote discriminator to 800.
