How to Configure Bidirectional Forwarding Detection
To configure BFD support for static routing, 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 gigabitethernet6/1
Step 4
no switchport
Switch(config-if)# no switchport
Step 5
ip address ip-address mask
Switch(config-if)# ip address 10.201.201.1
255.255.255.0
Step 6
bfd interval milliseconds min_rx milliseconds
multiplier interval-multiplier
Switch(config-if)# bfd interval 500 min_rx 500
multiplier 5
Step 7
exit
Switch(config-if)# exit
Step 8
ip route static bfd interface-type
interface-number ip-address [group group-name
[passive]]
Switch(config)# ip route static bfd
Gi6/1 10.1.1.1 group group1 passive
Step 9
ip route [vrf vrf-name] prefix mask {ip-address
| interface-type interface-number [ip-address]}
[dhcp] [distance] [name next-hop-name]
[permanent | track number] [tag tag]
Example:
Switch(config)# ip route 10.0.0.0 255.0.0.0
Gi6/1 10.201.201.2
Step 10
exit
Example:
Switch(config)# exit
Step 11
show ip static route
Example:
Switch# show ip static route

Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Configures an interface and enters interface configuration
mode.
Changes the interface to Layer 3.
Configures an IP address for the interface.
Enables BFD on the interface.
Exits interface configuration mode and returns to global
configuration mode.
Specifies a static route BFD neighbor.
The interface-type, interface-number, and ip-address
•
arguments are required because BFD support exists
only for directly connected neighbors.
Specifies a static route BFD neighbor.
Exits global configuration mode and returns to privileged
EXEC mode.
(Optional) Displays static route database information.
