Step 3 Verify the configuration.
On the computer of the Layer 2 network connected to Switch A, set the default gateway address
to the IP address of GE 1/0/1.1, that is, 10.10.10.1/24.
On the computer of the Layer 2 network connected to Switch B, set the default gateway address
to the IP address of GE 1/0/2.1, that is, 20.20.20.1/24.
After the configurations, computers of the two Layer 2 networks are isolated at Layer 2 and
interwork at Layer 3.
