Network requirements
On Router A, there are three equal-cost routes to the destination network
10.2.1.0 /24, as shown below:
<Sysname> display fib
Destination/Mask
10.2.1.0/24
10.2.1.0/24
10.2.1.0/24
Use the display loadsharing ip address command to display bandwidths on
interfaces.
<Sysname> display load-sharing ip address 10.2.1.0 24
There are/is totally 3 route entry(s) to the same destination network.

# The display shows that packets are load-shared according to their default
bandwidths.
Specify bandwidths fpr the three interfaces on Router A and observe the load
sharing.
