Usage Guidelines

Usage Scenario

If different VRRP versions are configured for devices in a VRRP backup group, a VRRPv2-enabled device receives only VRRPv2 Advertisement packets. After the VRRPv2-enabled device receives VRRPv3 Advertisement packets, it discards them. As a result, the devices in the VRRP backup group cannot negotiate their status. To resolve this issue, run the vrrp version-3 send-packet-mode command to configure a VRRPv3-enabled device to send VRRPv2 Advertisement packets so that the VRRPv2- and VRRPv3-enabled devices can negotiate their status.

Prerequisites

The VRRP version number of a device has been configured as 3 using this command.

Configuration Impact

If both the vrrp version-3 send-packet-mode and vrrp vrid version-3 send-packet-mode commands are run, the vrrp vrid version-3 send-packet-mode command takes precedence over the vrrp version-3 send-packet-mode command.

Precautions

Only a VRRPv3-enabled device can be configured to send Advertisement packets of a specified version.

Example

# Configure a VRRPv3-enabled device to send only VRRPv2 Advertisement packets.
