Information
Disabling BFD for Static Routes
If you disable BFD, all static route BFD sessions are torn down.
A nal 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 [prefix-list prefix-list-name] [interval interval min_rx min_rx multiplier
value role {active | passive}]
Congure 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 noties the BFD manager, which in turn noties the OSPF protocol that a link state change occurred.
Conguring 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.
