Configuring BFD to Monitor VPN Routes

You can configure BFD to monitor a VPN route to check whether the VPN route is reachable.

Usage Scenario

To rapidly monitor a VPN route, configure BFD to monitor it.

Pre-configuration Tasks

Before configuring BFD to detect a VPN route, complete the following task:

Configure network layer attributes for interfaces to ensure network connectivity.
Configure a VPN instance on each PE.

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 link to detect faults in a VPN route.

(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 VPN Routes: After configuring BFD to monitor a VPN route, verify the configuration, including the session type and status.
