• Change parameters for all static route sessions.
CONFIGURATION mode

To view session parameters, use the show bfd neighbors detail command, as shown in the
examples in
Displaying BFD for BGP Information
Disabling BFD for Static Routes
If you disable BFD, all static route BFD sessions are torn down.
A final Admin Down packet is sent to all neighbors on the remote systems, and those neighbors change
to the Down state.
To disable BFD for static routes, use the following command.
• Disable BFD for static routes.
CONFIGURATION mode
no ip route bfd
Configure BFD for OSPF
When using BFD with OSPF, the OSPF protocol registers with the BFD manager.
BFD sessions are established with all neighboring interfaces participating in OSPF. If a neighboring
interface fails, the BFD agent on the line card notifies the BFD manager, which in turn notifies the OSPF
protocol that a link state change occurred.
Configuring BFD for OSPF is a two-step process:
1. Enable BFD globally.
2. Establish sessions with OSPF neighbors.

Enabling BFD Globally
You must enable BFD globally on both routers.
To enable the BFD globally, use the following command.
• Enable BFD globally.
CONFIGURATION mode
bfd enable
Example of Verifying that BFD is Enabled
To verify that BFD is enabled globally, use the show running bfd command.
The bold line shows that BFD is enabled.
