The OSPFv3 process is started, and the OSPFv3 view is displayed.
Step 3 Run:
frr
The OSPFv3 IP FRR view is displayed.
Step 4 Run:
loop-free-alternate
OSPFv3 IP FRR is enabled to generate a loop-free backup link.
Step 5 (Optional) Run:
frr-policy route route-policy route-policy-name
OSPFv3 IP FRR filtering policies are configured.
After OSPFv3 IP FRR filtering policies are configured, only the OSPFv3 backup routes that
match the filtering conditions can be delivered to the forwarding table. To protect the traffic
over a specific OSPFv3 route, you can configure a filtering policy that matches the OSPFv3
route to ensure that the route can be added to the forwarding table. When this route becomes
faulty, OSPFv3 can fast switch the traffic to a backup link.

6.11.3 (Optional) Binding OSPFv3 IP FRR and BFD

This section describes how to bind OSPFv3 IP FRR and BFD so that link faults can be detected
rapidly. This ensures that traffic is rapidly switched to the backup link in the case of link failures.
Context
During the configuration of OSPFv3 IP FRR, the lower layer needs to fast respond to the link
change so that traffic can be rapidly switched to the backup link in the case of a link failure.
Bind BFD to the link status so that link faults can be detected rapidly. This ensures that traffic
is rapidly switched to the backup link in the case of link failures.
Binding OSPFv3 IP FRR and BFD can configure in a specified process or on a specified
interface. The priority of BFD configured on an interface is higher than that of BFD configured
in an OSPFv3 process. If BFD is enabled on an interface, a BFD session is established according
to the BFD parameters set on the interface.

NOTE
OSPFv3 can generate the loop-free backup link only when the OSPFv3 IP FRR traffic protection inequality
is met.
