Configuring Protocol-based BFD
Configuring BFD for OSPF
After discovering neighbors by sending hello packets, OSPF notifies BFD of the neighbor addresses,
and BFD uses theses 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 not 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 OSPF, you need
to configure OSPF first.
Follow these steps to enable BFD on an OSPF interface:

z
One network segment can only belong to one area and you must specify each OSPF interface to
belong to the specific area.
z
Both ends of a BFD session must be on the same network segment and in the same area.

For OSPF configuration, refer to OSPF Configuration in the IP Routing Volume.
