Virtual Router Redundancy Protocol (VRRP) Interface Configurations.
Upon configuration, this profile is to be referenced from either a
VLAN profile or a port profile.
VRRP specifies an election protocol to provide the virtual router function
described below. All protocol messaging is performed using IP multicast
datagrams, thus the protocol can operate over a variety of multiaccess LAN
technologies supporting IP multicast. The virtual router MAC address is used
as the source in all periodic VRRP messages sent by the Active router to enable
bridge learning in an extended LAN.
A virtual router is defined by its virtual router identifier (VRID) and a set
of IP addresses. A VRRP router may associate a virtual router with its real
addresses on an interface, and may also be configured with additional virtual
router mappings and priority for virtual routers it is willing to standby.
A Standby router will not attempt to preempt the Active unless it has higher
priority. This eliminates service disruption unless a more preferred path
becomes available. It is also possible to administratively prohibit all
preemption attempts. The only exception is that a VRRP router will always
become Active of any virtual router associated with addresses it owns. If the
Active becomes unavailable then the highest priority Standby will transition to
Active after a short delay, providing a controlled transition of the virtual
router responsibility with minimal service interruption.

AOS-CX : VRRP can be configured on physical ports, VLAN interfaces and LAG interfaces.
All such configurations work in the mentioned interfaces context.
VRRP mandates the associated interface to be routing interface.
