BFD for static routes configuration example (direct next hop)
Network requirements
Configure the following, as shown in Figure 3 :
• Configure a static route to subnet 120.1.1.0/24 on Switch A.
• Configure a static route to subnet 121.1.1.0/24 on Switch B.
• Enable BFD for both routes.
• Configure a static route to subnet 120.1.1.0/24 and a static route to subnet 121.1.1.0/24 on Switch
C.
When the link between Switch A and Switch B through the Layer 2 switch fails, BFD can detect the failure
immediately. Switch A then communicates with Switch B through Switch C.

Device Interface IP address
Switch A VLAN-interface 10 12.1.1.1/24
Switch A VLAN-interface 11 10.1.1.102/24
Switch B VLAN-interface 10 12.1.1.2/24
Switch B VLAN-interface 13 13.1.1.1/24
Switch C VLAN-interface 11 10.1.1.100/24
Switch C VLAN-interface 13 13.1.1.2/24
Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown.)
2. Configure static routes and BFD:
# Configure static routes on Switch A and enable BFD control mode for the static route that
traverses the Layer 2 switch.
