    Release Information

    Statement introduced before Junos OS Release 7.4.

    Statement introduced in Junos OS 11.3 for the QFX Series.

    Description

    In a Virtual Router Redundancy Protocol (VRRP) configuration, determine whether or not an interface accepts packets destined for the virtual IP address:

    • accept-data—Enable the interface to accept packets destined for the virtual IP address.
    • no-accept-data—Prevent the interface from accepting packets destined for the virtual IP address.

    Default

    If the accept-data statement is not configured, the master router responds to ARP requests only.

    The accept-data statement has the following restrictions and limitations:

    • If the master router owns the virtual IP address or if the priority of the master router is set to 255, the accept-data statement becomes inapplicable.
    • If the master router owns the virtual IP address, the master router responds to Internet Control Message Protocol (ICMP) message requests.
    • If you want to restrict the incoming IP packets to ICMP only, you must configure firewall filters to accept only ICMP packets.
    • If you include the accept-data statement, your routing platform configuration does not comply with RFC 3768 (see section 6.4.3 of RFC 3768, Virtual Router Redundancy Protocol (VRRP).

    Required Privilege Level

    interface—To view this statement in the configuration.

    interface-control—To add this statement to the configuration.
