[RouterA] ip route-static 192.168.2.0 24 serial 2/1
[RouterA] ip route-static 192.168.2.0 24 serial 2/2
# On Router B, configure a static route to the segment 192.168.1.0/24 where Host A resides.
<RouterB> system-view
[RouterB] ip route-static 192.168.1.0 24 serial 2/0
[RouterB] ip route-static 192.168.1.0 24 serial 2/1
[RouterB] ip route-static 192.168.1.0 24 serial 2/2
3. Configure the standby interfaces and switch delays on Router A:
# Specify interfaces Serial 2/1 and Serial 2/2 on Router A to back up Serial 2/0, and assign
them the priorities 30 and 20, respectively.
[RouterA] interface serial 2/0
[RouterA-Serial2/0] standby interface serial 2/1 30
[RouterA-Serial2/0] standby interface serial 2/2 20
# Configure switchover delays to 10 seconds.
[RouterA-Serial2/0] standby timer delay 10 10
4. Verify the configuration on Router A:
# Display the state of the active and standby interfaces.
[RouterA-Serial2/0] display standby state

# Manually shut down the active interface Serial 2/0.
[RouterA-Serial2/0] shutdown
# 10 seconds after the active interface was shut down, standby interface Serial 2/1 with a higher
priority is enabled. Then you can view the state of the active and standby interfaces.
[RouterA-Serial2/0] display standby state
