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 via
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.

Configuration procedure
Configure Switch B
1.
Figure
10, Host A and Host B belong to the same VLAN, and connect to Switch B via
