Enabling ARP Bidirectional Isolation

Address Resolution Protocol (ARP) bidirectional isolation enables the router to process ARP request and reply packets separately, improving the fault locating efficiency when a large number of ARP packets are received in a short period.

Context

Configure ARP bidirectional isolation on interfaces of the router.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number [ .sub-interface-number ]

    The interface view is displayed.

  3. Run arp-safeguard enable

    ARP bidirectional isolation is enabled.

    ARP bidirectional isolation is mutually exclusive to of L2VPN and proxy ARP. Before configuring ARP bidirectional isolation, delete L2VPN and proxy ARP configurations, if present.

  4. Run commit

    The configuration is committed.
