• 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 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}]
Congure BFD for OSPF
When you use 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 noties the BFD manager, which in turn noties the OSPF
protocol that a link state change has occurred.
Conguring BFD for OSPF is a two-step process:
1 Enable BFD globally.
2 Establish sessions with OSPF neighbors.
