Configuring ARP Proxy on a VPLS Network

Configuring ARP Proxy on a VPLS Network


To prevent bogus ARP packets at the PW side from being broadcast to the AC side on a VPLS network, enable ARP proxy over VPLS on a PE.

ARP packets at the PW side are sent to the CPU for processing.
  • If the ARP packets are ARP Request packets and the destination IP addresses in the packets match DHCP snooping binding entries, the device constructs ARP Reply packets based on the DHCP snooping binding entries. The device then sends the ARP Reply packets to the requester at the PW side.
  • If the ARP packets are not ARP Request packets or the destination IP addresses in the packets do not match a DHCP snooping binding entry, the device forwards these ARP packets to the destination.

This function works with DHCP snooping over VPLS. For the configuration of DHCP snooping over VPLS, see Enabling DHCP Snooping.


Only the S5720HI supports this function.


  1. Run system-view

    The system view is displayed.

  2. Run arp over-vpls enable

    ARP proxy is enabled on the device located on a VPLS network.

    By default, ARP proxy is disabled on a device of a VPLS network.
