Usage Guidelines

Usage Scenario

If devices in a VRRP group use different VRRP version numbers, the VRRP group may fail to negotiate the status. This is because a VRRPv2-enabled device can only receive VRRPv2 Advertisement packets and discards the received VRRPv3 Advertisement packets. You can set the mode in which VRRP Advertisement packets are sent on the VRRPv3-enabled device so that the VRRPv2-enabled and VRRPv3-enabled devices can negotiate the status.

Precautions

Only VRRPv3 supports this command.
If the vrrp version-3 send-packet-mode command is used in the system view and interface view simultaneously, the configuration in the interface view takes effect.

If a large number of VRRP groups are configured, v2v3-both is not recommended.
