Disable interfaces from receiving and sending OSPFv3 packets
Follow these guidelines when you disable interfaces from receiving and sending OSPFv3 packets:
• Multiple OSPFv3 processes can disable the same interface from receiving and sending OSPFv3
packets. Using the silent-interface command disables only the interfaces associated with the current
process.
• After an OSPF interface is set to silent, direct routes of the interface can still be advertised in
Intra-Area-Prefix-LSAs via other interfaces, but other OSPFv3 packets cannot be advertised. No
neighboring relationship can be established on the interface. This feature can enhance the
adaptability of OSPFv3 networking.

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.
