(Optional) Configuring the VRRP Version Number

(Optional) Configuring the VRRP Version Number


IPv4 VRRP supports VRRPv2 and VRRPv3. If devices in a VRRP group use different VRRP versions, VRRP Advertisement packets will fail to be forwarded.
  • A VRRPv2 group can send and receive only VRRPv2 Advertisement packets, and discards received VRRPv3 Advertisement packets.

  • A VRRPv3 group can send and receive both VRRPv2 and VRRPv3 Advertisement packets. The VRRPv3 group can communicate with both VRRPv2 and VRRPv3 groups.


  1. Run system-view

    The system view is displayed.

  2. Run vrrp version { 2 | 3 }

    The VRRP version number is set.

    By default, VRRPv2 is used.

    If VRRPv3 is used, run either of the following commands as required:

    • To configure the device to send VRRP Advertisement packets of a specified version, run the vrrp compatible-version { 2 | 3 | all } command in the system view.
    • To configure the device's interface to send VRRP Advertisement packets of a specified version, run the vrrp vrid virtual-router-id compatible-version { 2 | 3 | all } command in the view of the interface on which the VRRP group is configured.

  3. Run commit

    The configuration is committed.
