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.
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.
Follow these steps to configure BFD for OSPFv3:
To do...
Enter system view
Enter OSPFv3 view
Specify a router ID
Quit the OSPFv3 view
Enter interface view
Enable an OSPFv3 process on the
interface
Enable BFD on the interface
