Figure 6 Network diagram for proxy ARP
Configuration procedure
# Specify the IP address of interface GigabitEthernet 0/2.
<Device> system-view
[Device] interface gigabitethernet 0/2
[Device-GigabitEthernet0/2] ip address 192.168.10.99 255.255.255.0
# Enable proxy ARP on interface GigabitEthernet 0/2.
[Device-GigabitEthernet0/2] proxy-arp enable
[Device-GigabitEthernet0/2] quit
# Specify the IP address of interface GigabitEthernet 0/1.
[Device] interface gigabitethernet 0/1
[Device-GigabitEthernet0/1] ip address 192.168.20.99 255.255.255.0
# Enable proxy ARP on interface GigabitEthernet 0/1.
[Device-GigabitEthernet0/1] proxy-arp enable
[Device-GigabitEthernet0/1] quit
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 Figure 7 , Host A and Host B belong to the same VLAN, and connect to the switch via
GigabitEthernet 1/3 and GigabitEthernet 1/1 respectively. The switch connects to the device via
GigabitEthernet 1/2.
Configure port isolation on GigabitEthernet 1/3 and GigabitEthernet 1/1 of the switch. Enable local
proxy ARP on the device to allow communication between Host A and Host B at Layer 3.
