Network requirements
Use interfaces GigabitEthernet 0/1 and GigabitEthernet 0/3 on LB to back up the active interface
GigabitEthernet 0/2, assigning interface GigabitEthernet 0/1 a higher priority, and configure
switchover delays.

Configuration procedure
1. Configure IP addresses:
Follow
Figure 63 to configure the IP address and subnet mask for each interface. (Details not
shown.)
2. Configure a static route:
# On LB, configure a static route to the segment 192.168.2.0/24 where Host B resides.
system-view
[LB] ip route-static 192.168.2.0 24 gigabitethernet 0/1 1.1.1.2
[LB] ip route-static 192.168.2.0 24 gigabitethernet 0/2 2.2.2.2
[LB] ip route-static 192.168.2.0 24 gigabitethernet 0/3 3.3.3.2
# On Router, configure a static route to the segment 192.168.1.0/24 where Host A resides.
system-view
[Router] ip route-static 192.168.1.0 24 gigabitethernet 0/1 1.1.1.1
[Router] ip route-static 192.168.1.0 24 gigabitethernet 0/2 2.2.2.1
[Router] ip route-static 192.168.1.0 24 gigabitethernet 0/3 3.3.3.1
3. Configure the standby interfaces and switchover delays on LB:
# Specify interfaces GigabitEthernet 0/1 and GigabitEthernet 0/3 on LB to back up
GigabitEthernet 0/2, and assign them the priorities 30 and 20, respectively.
