Configuring Bfd For Ospfv3; Configuring Ospfv3 Frr - HP FlexFabric 12900E Series Configuration Manual

Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enable OSPFv3 NSR.

Configuring BFD for OSPFv3

Bidirectional forwarding detection (BFD) provides a mechanism to quickly detect the connectivity of
links between OSPFv3 neighbors, improving 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 1 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.
To configure BFD for OSPFv3:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Specify a router ID.
4. Quit the OSPFv3 view.
5. Enter interface view.
6. Enable
process on the interface.
7. Enable
interface.

Configuring OSPFv3 FRR

A primary link failure can cause packet loss and even a routing loop until OSPFv3 completes routing
convergence based on the new network topology. OSPFv3 FRR enables fast rerouting to minimize
the failover time.

practice, enable OSPFv3 NSR for
each process if multiple OSPFv3
processes exist.
