2-2source IP address being the destination IP address of the ARP request). After receiving the ARPresponse, Host A creates an ARP entry, in which the destination IP address is the IP address ofHost D (192.168.1.30/16), and the MAC address is that of VLAN-interface 3. The following packetssent from Host A to Host D will all be sent to VLAN-interface 3 of the switch, and then the switchforwards the packets in Layer 3 to Host D, so as to realize the Layer 3 connectivity between Host Aand Host D.Configuring Proxy ARPFollow these steps to configure proxy ARP:To do… Use the command… RemarksEnter system view system-view —Enter VLAN interface view interface Vlan-interfacevlan-id —Enable proxy ARP arp proxy enable RequiredDisabled by default.Display the proxy ARPconfigurationdisplay arp proxy [ interfaceVlan-interface vlan-id ] Available in any viewProxy ARP Configuration ExamplesProxy ARP Configuration ExampleNetwork requirementsz The IP address of Host A is 192.168.0.22/16, and that of Host D is 192.168.1.30/16.z Create VLAN 3 and VLAN 4 on the switch.z The IP address of VLAN-interface 3 is 192.168.0.27/24, and that of VLAN-interface 4 is192.168.1.27/24.z Enable proxy ARP on VLAN-interface 3 and VLAN-interface 4 to realize the communicationbetween Host A and Host D.
