Configuring Gr Helper; Configuring Bfd For Ospfv3 - HP 6125XLG Configuration Manual

Configuring GR Helper

You can configure the GR Helper capability on a GR Helper.
To configure GR Helper
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enable the GR Helper
capability.
4. Enable strict LSA
checking.

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 an OSPFv3 process
on the interface.
7. Enable BFD on the interface.
