Procedure
Step 1 Configure the network layer attributes.
# Configure IP addresses of all interfaces as shown in
The configuration details are not mentioned here.
# Configure a static route to Host B network segment on Router A.
<RouterA> system-view
[RouterA] ip route-static 10.20.1.0 255.255.255.0 pos1/0/0
[RouterA] ip route-static 10.20.1.0 255.255.255.0 pos2/0/0
[RouterA] ip route-static 10.20.1.0 255.255.255.0 Pos3/0/0
# Configure a static route to Host A network segment on Router B.
<RouterB> system-view
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos1/0/0
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos2/0/0
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos3/0/0
# 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.
