Configuring Proxy ARP Between VLANs

Proxy ARP between VLANs allows communication between devices in different VLANs.

Usage Scenario

If two hosts belong to different VLANs and communication is required between them, proxy ARP between VLANs must be enabled on interfaces associated with the VLANs.

Pre-configuration Tasks

Before configuring proxy ARP between VLANs, configure VLAN aggregation.

Configuring an IP Addresses for an Interface: The IP address assigned to an interface needs to be in the same network segment with the IP addresses of the users of all the VLANs associated to this interface.

(Optional) Associating the Sub-interface with a VLAN: Before you configure proxy ARP between VLANs on Ethernet sub-interfaces, GE interfaces, or Eth-Trunk sub-interfaces, associate the sub-interface with a VLAN.

Enabling Proxy ARP Between VLANs: To enable communication between devices in different VLANs, proxy ARP between VLANs is required.

Verifying the Configuration of Proxy ARP Between VLANs: After configuring proxy ARP between VLANs, verify the configuration.
