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 a router that is acting as the master router accepts all packets destined for the virtual IP address.

  • accept-data—Enable the master router to accept all packets destined for the virtual IP address.
  • no-accept-data—Prevent the master router from accepting packets other than the ARP packets destined for the virtual IP address.

Default

If the router acting as the master router is the IP address owner or has its priority set to 255, the master router, by default, responds to all packets sent to the virtual IP address. However, if the router acting as the master router does not own the IP address or has its priority set to a value less than 255, the master router responds only to ARP requests.

Note:

  • If you want to restrict the incoming IP packets to ICMP packets 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).
