After completing preceding configurations, use the ping command to verify the connectivity between 

Host A and Host D. 

As shown in 

, Host A and Host B belong to the same VLAN, and connect to Switch B via 

GigabitEthernet2/0/1 and GigabitEthernet2/0/3 respectively. Switch B connects to Switch A via 

GigabitEthernet2/0/2. 

Configure Layer 2 and Layer 3 port isolation on GigabitEthernet2/0/1 and GigabitEthernet2/0/3 of 

Switch B. Enable proxy ARP on Switch A to allow communication between Host A and Host B.
