Configure an IPv4 address and local proxy ARP on a PVLAN interface

Enable the Local Proxy ARP feature in the primary VLAN to allow communication between isolated hosts and between hosts connected to different community VLANs within the same PVLAN domain.

You can configure a Layer 3 (L3) VLAN interface, assign an IPv4 address, and enable local proxy ARP in the primary VLAN.

NOTE: To enable the Local Proxy ARP feature, you must assign an IPv4 address to the primary VLAN.
  1. Enter Configuration mode.
    OS10# configure terminal
  2. Enter VLAN Interface mode.
    OS10(config)# interface vlan 10
  3. Configure an IP address.
    OS10(conf-if-vl-10)# ip address 10.1.1.1/24
  4. Enable the local proxy ARP in the primary VLAN.
    OS10(conf-if-vl-10)# ip local-proxy-arp
    OS10(conf-if-vl-10)# show configuration
    !
