Layer 3 communication is implemented between the sub-VLANs.

# Create the super VLAN and the sub-VLANs. Add gigabitethernet2/0/2 to VLAN 2 and 

gigabitethernet2/0/1 to VLAN 3. Configure the IP address 192.168.10.100/16 for the interface of VLAN 

10.

The ping operation from Host A to Host B is unsuccessful because they are isolated at Layer 2 and 

Layer 3.

The ping operation from Host A to Host B is successful after the configuration. 

As shown in 

, Switch B is attached to Switch A. VLAN 5 on Switch B is an isolate-user-VLAN, 

which includes uplink port GigabitEthernet2/0/2 and two secondary VLANs, VLAN 2 and VLAN 3. 

GigabitEthernet2/0/3 belongs to VLAN 2, and GigabitEthernet2/0/1 belongs to VLAN 3.
