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:
To do...
Enter system view
Enter interface view
Enable BFD on the interface
Use the command...
system-view
bfd session init-mode { active
| passive }
