Configuring BFD Session Parameters on the Interface

The steps in this procedure show how to configure BFD on the interface by setting the baseline BFD
session parameters on an interface. Repeat the steps in this procedure for each interface over which you
want to run BFD sessions to BFD neighbors.
To configure BFD session parameters, perform this task:
Command or Action
Step 1
enable
Switch> enable
Step 2
configure terminal
Switch# configure terminal
Step 3
interface type number
Switch(config)# interface gigabitethernet 6/1
Step 4
bfd interval milliseconds min_rx milliseconds multiplier
interval-multiplier
Switch(config-if)# bfd interval 50 min_rx 50 multiplier 5
Switch(config-if)# no bfd echo
Step 5
end
Switch(config-if)# end
Configuring BFD Support for Dynamic Routing Protocols
You can enable BFD support for dynamic routing protocols at the router level to enable BFD support
globally for all interfaces or you can configure BFD on a per-interface basis at the interface level.

Configuring BFD Support for BGP
This section describes the procedure for configuring BFD support for BGP so that BGP is a registered
protocol with BFD and will receive forwarding path detection failure messages from BFD.
