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.

Configure BFD for OSPF
BFD for OSPF is only supported on the S4820T platform.
When using BFD with OSPF, the OSPF protocol registers with the BFD manager on the RPM. 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.
