# Configure Host A and Host B to use Router A and Router B as their gateways respectively.
The configuration details are omitted here.
After the configuration, Host A and Host B can Ping through each other.
Step 2 Configure the interface backup on Router B.
# Configure POS 2/0/0 as the active interface and POS 1/0/0 and POS 3/0/0 as the standby
interfaces with the priorities of 40 and 20 respectively.
[RouterB] interface pos 2/0/0
[RouterB-Pos2/0/0] standby interface pos1/0/0 40
[RouterB-Pos2/0/0] standby interface pos3/0/0 20
# Configure the percentage threshold of load balancing and the bandwidth of the active interface.
[RouterB-Pos2/0/0] standby bandwidth 40000
[RouterB-Pos2/0/0] standby threshold 50 30
Step 3 Verify the configuration.
# Running the display standby state command on Router B, you can view information about
the status of active and standby interfaces. As shown in the command output, POS 2/0/0 is in
the Up state. POS 1/0/0 and POS 3/0/0 are in the Standby state. Also, you can run the display
standby flow command to view traffic changes on POS 2/0/0.

# Router A sends great traffic to Host B, making the traffic on POS 2/0/0 exceeds 20 Mbit/s.
After 30 seconds, you can view the state of the active and standby interfaces on Router B again
and you can find that both POS 2/0/0 and POS 1/0/0 are Up.
