To establish a BFD session:
Step Task
1 Establish BFD sessions for all neighbors that are the next hop
of a static route.
Verify that sessions have been created for static routes using the command
in Figure 9-10. View detailed session information using the command
in Figure 9-8.

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.
View session parameters using the command
page 179.
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
