MODE
transition-mode
Overview
Use this command to configure the IPv4 transition mode. Transition mode allows
you to upgrade from VRRPv2 to VRRPv3 and gives interoperability between
VRRPv2 and VRRPv3.
If transition-mode is set to
true
, then the IPv4 transition mode is enabled and
VRRPv2 and VRRPv3 advertisements are sent allowing VRRPv2 and VRRPv3
interoperability. Received VRRPv2 advertisement packets are accepted and
processed when transition-mode is true.
If transition-mode is set to
false
, then the IPv4 transition mode is disabled and only
VRRPv3 advertisements are sent. Received VRRPv2 advertisement packets are
dropped.
Note the
advertisement-interval
should not be configured to less than 1 second
when using transition-mode. VRRPv2 can only use advertisements in whole
second intervals.
Syntax

Examples
The example below shows you how to configure IPv4 transition-mode as true for
VRRP VR ID 5 on vlan2:
awplus#
configure terminal
awplus(config)#
router vrrp 5 vlan2
awplus(config-router)#
transition-mode true
Parameter
Description
true
Transition mode is enabled. This results in VRRPv2 and VRRPv3 IPv4
advertisements being sent. Transition mode is only available on
VRRPv3 for interoperability with VRRPv2 while upgrading to VRRPv3.
false
Transition mode is disabled. This stops VRRPv2 IPv4 advertisements
being sent. Only VRRPv3 advertisements are sent when disabled.
Disable transition-mode after upgrading from VRRPv2 to VRRPv3.
