Configuring a Static BFD Session with Automatically Negotiated Discriminators

You can configure a static BFD session with automatically negotiated discriminators on a local device to enable the local device to interwork with the device on which a BFD session is dynamically set up. The static BFD session with automatically negotiated discriminators is used to monitor static routes.

Usage Scenario

If a dynamic BFD session is set up on the remote device, you must configure a static BFD session with automatically negotiated discriminators on the local device to interwork with the remote device and to allow static routes to track BFD.

Pre-configuration Tasks

Before configuring a static BFD session with automatically negotiated discriminators, complete the following tasks:

Connect interfaces.
Assign an IP address to each Layer 3 interface.

Enabling BFD Globally: BFD must be enabled globally before BFD is configured.

Establishing a BFD Session: You can establish a static BFD session with automatically negotiated discriminators on both ends of a link to allow a device to rapidly detect faults in a link.

(Optional) Changing the BFD Detection Time: You can change the BFD detection time to more efficiently use a BFD session to monitor links on a network.

(Optional) Setting the BFD WTR Time: You can set the BFD wait to restore (WTR) time to prevent an application from switching between the master and slave devices due to BFD session flapping.

(Optional) Configuring a Description for a BFD Session: You can configure a description for a BFD session to identify this session.

(Optional) Configuring a Priority for a BFD Session: This section describes how to configure a priority for a BFD session.

Verifying the Configuration of a Static BFD Session with Automatically Negotiated Discriminators: After a static BFD session with automatically negotiated discriminators is successfully set up, you can view information about the BFD session, such as the static session type and automatically negotiated discriminators.
