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
One network segment can only belong to one area and you must specify each OSPF interface to
belong to the specific area.
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.
Configuring BFD for IS-IS
Before the following configuration, configure IS-IS basic functions on each node.
Follow these steps to enable BFD on an IS-IS interface:
To do...
Enter system view
Enter interface view
Enable IS-IS on the interface
Use the command...
bfd authentication-mode
{ md5 key-id key | sha1 key-id
key | simple key-id password }
Use the command...
system-view
interface interface-type
interface-number
ospf bfd enable
Use the command...
system-view
interface interface-type
interface-number
isis enable [ process-id ]
1-7
Remarks
Optional
By default, the interface
operates in the
non-authentication mode.
