Usage Guidelines

Usage Scenario

OSPF IP FRR allows devices to fast switch traffic from faulty links to back up links without interrupting traffic. This function protects traffic and greatly improves the reliability of OSPF networks. OSPF IP FRR must be configured in the OSPF FRR view. The frr command run in the OSPF view creates and displays the OSPF FRR view.

Follow-up Procedure

The frr command run in the OSPF view creates and displays the OSPF FRR view only, but cannot enable the OSPF IP FRR function. Run the loop-free-alternate command in the OSPF view to enable OSPF IP FRR to create the loop-free backup route.
