1.5.3 Configuring Routed Proxy ARP
Routed proxy ARP implements communication between devices on different subnets.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Routed proxy ARP can be enabled on Ethernet interfaces, Ethernet sub-interfaces, VE interfaces,
Eth-Trunk interfaces, Eth-Trunk sub-interfaces, and VLANIF interfaces. The preceding
interfaces and sub-interfaces are Layer 3 interfaces and sub-interfaces.
Step 3 Run:
arp-proxy enable
Routed proxy ARP is enabled on the interface.
By default, routed proxy ARP is disabled on an interface.
----End
1.5.4 Checking the Configuration
After configuring routed proxy ARP, you can view the configuration.
Procedure
l Run the display arp interface interface-type interface-number [ vid vlan-id [ cevid cevlan-
id ] ] command to check ARP entries on the specified interface.
l Run the display arp vpn-instance vpn-instance-name [ dynamic | static ] command to
check ARP entries in the specified VPN instance.
l Run the display arp dynamic command to check dynamic ARP entries.
l Run the display arp statistics { all | interface interface-type interface-number } command
to check statistics on ARP entries on the AR150/200 or the specified interface.
----End
Example
# Run the display arp interface command, and you can view ARP entries on Eth1/0/0.
