Min tx interval: 200000 - Min rx interval: 200000
Min Echo interval: 0
3.4.4 Example of Configuring BFD
for Static Route
3.4.4.1 Network Requirement
RouterA and RouterB are interconnected through a L2 switch. Both routers
run the static route protocol and enable the BFD for static route on the
interface. After a link failure between RouterB and L2 switch occurs, BFD
detects the failure and notifies the static route of the failure, triggering the
static route removal from RIB and preventing the routing error.

3.4.4.3 Configuration Steps
1) RouterA Configuration
# Configure the Routed Port, the IP address, the BFD session parameter for
Router A:
DES-7200# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)# interface GigabitEthernet2/1
DES-7200(config-if)# no switchport
DES-7200(config-if)# ip address 192.168.3.1 255.255.255.0
DES-7200(config-if)# bfd interval 200 min_rx 200 multiplier 5
# Configure the Routed Port gi1/1:
DES-7200(config-if)# exit
DES-7200(config)# interface GigabitEthernet1/1
DES-7200(config-if)# no switchport
DES-7200(config-if)# ip address 192.168.1.1 255.255.255.0
