Enhancing OSPF Network Reliability

Configuring OSPF GR and BFD for OSPF improves OSPF network convergence and enhances OSPF reliability.

Configuring OSPF GR: This section describes how to configure OSPF GR to avoid traffic interruption and route flapping caused by the active/standby switchover.

Configuring BFD for OSPF: After BFD for OSPF is enabled, when a link fails, the device rapidly detects the failure, notifies the OSPF process or interface of the fault, and instructs OSPF to recalculate routes. This speeds up OSPF network convergence.
