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 configure a mode in which VRRP Advertisement packets are sent so that devices running VRRPv2 and VRRPv3 in the VRRP group can negotiate the status.
Precautions
Only VRRPv3 supports this command.
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.
If a large number of VRRP groups are configured, v2v3-both is not recommended.
