Configuring BFD to Monitor an IP Link

You can configure a single-hop BFD session to rapidly detect faults in direct links on a network.

Usage Scenario

To rapidly monitor an IP link on a network, configure BFD to detect faults in the IP link.

Pre-configuration Tasks

Before configuring BFD to monitor an IP link, complete the following tasks:

Set link layer protocol parameters for each interface to ensure that the link protocol status of the interface is Up.
Assign an IP address to each interface.

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

Establishing a BFD Session: You can establish a BFD session on both ends of a direct link to rapidly detect link faults.

(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) Setting the Priority of a BFD Session: You can set a priority for a BFD session. Packets of a BFD session with a higher priority are preferentially forwarded.

Verifying the Configuration of BFD to Monitor an IP Link: After configuring BFD to monitor an IP link, verify the configurations, including the minimum intervals at which BFD control packets are sent and received, WTR time, and description of a BFD session.
