Changing static route session parameters
BFD sessions are configured with default intervals and a default role. The parameters that can be
configured are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role.
These parameters are configured for all static routes; if you change a parameter, the change affects all
sessions for static routes.
To change parameters for static route sessions:
Step Task
1 Change parameters for all static route
sessions.

Disabling BFD for static routes
If BFD is disabled, 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:
Step Task
1 Disable BFD for static routes.

Configuring BFD for OSPF

BFD for OSPF is only supported on platforms:
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.
