Configuring BFD for OSPFv3

Bidirectional forwarding detection (BFD) provides a mechanism to quickly detect the connectivity of links

between OSPFv3 neighbors, thus to improve the convergence speed of OSPFv3. For more information

about BFD, see High Availability Configuration Guide.
After discovering neighbors by sending hello packets, OSPFv3 notifies BFD of the neighbor addresses,
and BFD uses these addresses to establish sessions. Before a BFD session is established, it is in the down

state. In this state, BFD control packets are sent at an interval of no less than one second to reduce BFD

control packet traffic. After the BFD session is established, BFD control packets are sent at the negotiated

interval, thereby implementing fast fault detection.
To configure BFD for OSPFv3, you need to configure OSPFv3 first.
