(VRRP)
priorityZeroTx Total number of VRRP advertisements with a priority of 0
that this virtual router has sent. The priority of zero (0)
indicates that this virtual router was acting as Master but
stopped participating in VRRP. Used to trigger backup
routers to quickly transition to Master without having to
wait for the current Master to time out.
State Current state of the VRRP router. One of the following:
■
Master
— In this state, the router is the active
forwarding router for all IP addresses that are
associated with the virtual router.
■
Backup
— In this state, the router monitors the
availability of the Master router. If the Master router
fails, the Backup router assumes forwarding
responsibility for all IP addresses that are associated
with the virtual router.
■
Initialize
— Transitional state between
Backup
and
Master
states. Typically indicates that the virtual
router has been configured but not enabled, or that
the virtual router mode has been set to
disabled
.
In this state, the router waits for a Startup event.
When the router receives the Startup event, it
broadcasts an ARP request that contains the virtual
router MAC address for all IP addresses that are
associated with the virtual router and transitions to the
Master state. If the Startup event is not received, it
transitions to the Backup state.
