Configuring BFD involves a two-fold approach: configuring BFD on the IP interfaces that will use BFD 
and then configuring Layer 3 protocols to use BFD (see 

The following steps provide a brief tutorial for configuring a BFD interface and related parameters:

4 Configure a BFD interface using the 

command with the name of an existing IP 

interface. For example:

-> ip bfd-std interface bfd-vlan-101

5 Configure a global transmit time interval for all BFD interfaces using the 

command. This command defines a default transmit value that is automatically applied when a BFD inter-
face is created. For example:

-> ip bfd-std transmit 500

6 Configure the transmit time interval for a specific BFD interface using the 

 command. The value set with this command overrides the global transmit value configured for the 

switch. For example: 

-> ip bfd-std interface bfd-vlan-101 transmit 500

7 Configure a global receive time interval for all BFD interfaces using the 

This command defines a default receive time value that is automatically applied when a BFD interface is 
created. For example:

-> ip bfd-std receive 500

8 Configure the receive time interval for a specific BFD interface using the 

 

command. The value set with this command overrides the global receive time value configured for the 
switch:

-> ip bfd-std interface bfd-vlan-101 receive 500

9 Configure the BFD interface dead interval multiplier value using the 

 

command. For example:

-> ip bfd-std interface bfd-vlan-101 multiplier 5

10 Configure the global operational mode and echo status for the BFD protocol using the 

command. This command defines a default mode and status that is automatically applied when a BFD 
interface is created. For example:

-> ip bfd-std mode echo-only

11 Configure the operational mode and echo status for a specific BFD interface using the 

 command. The mode and status set with this command overrides the global mode and status 

configured for the switch. For example:

-> ip bfd-std interface bfd-vlan-101 mode echo-only
