Configure BFD for Static Routes
Configuring BFD for static routes is supported on Z9000 S4810 S4820T S6000.
BFD offers systems a link state detection mechanism for static routes. With BFD, systems are notified to
remove static routes from the routing table as soon as the link state change occurs, rather than waiting
until packets fail to reach their next hop.
Configuring BFD for static routes is a three-step process:
1. Enable BFD globally.
2. Configure static routes on both routers on the system (either local or remote).
3. Configure an IP route to connect BFD on the static routes using the ip route bfd command.

Changing Static Route Session Parameters
BFD sessions are configured with default intervals and a default role.
The parameters you can configure 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, use the following command .
• Change parameters for all static route sessions.
