After completing preceding configurations, use the ping command to verify the connectivity between
Host A and Host D.
Local proxy ARP configuration example in case of
port isolation

Network requirements

As shown in
GigabitEthernet 1/0/3 and GigabitEthernet 1/0/1 respectively. Switch B connects to Switch A through
GigabitEthernet 1/0/2.
Configure port isolation on GigabitEthernet 1/0/3 and GigabitEthernet 1/0/1 of Switch B to isolate
Host A from Host B at Layer 2. Enable local proxy ARP on Switch A to allow communication between
Host A and Host B at Layer 3.
In this configuration example, suppose all traffic between the hosts is blocked, so you need to configure
local proxy ARP on VLAN-interface 2 of Switch A to enable communication between Host A and Host B.
If the two ports (GigabitEthernet 1/0/3 and GigabitEthernet 1/0/1) on Switch B are isolated only at
Layer 2, you can enable communication between the two hosts by configuring local proxy ARP on
VLAN-interface 2 of Switch B.
Figure 10, Host A and Host B belong to the same VLAN, and connect to Switch B through
