490 CHAPTER 17: VIRTUAL ROUTER REDUNDANCY (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 tim e out.
State Current state of the VRRP router. One of the following:
■Master — In this state, the rou ter is the active
forwarding router for all IP addresses that are
associated with the virtual router.
■Backup — In this state, the rou ter monitors the
availability of the Mas ter router. If the Mas ter router
fails, the Backup router assumes forwarding
responsibility for all IP addresses that are associated
with the virtual rou ter.
■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 St artup 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.
Type Type of virtual router: primary or back up
versionErrors Total number of VRRP advertisements with an unknown
or unsupported version number that this virtual router has
received
VLAN Index Index number of the virtual LAN (VLAN) on which the
virtual router is defined
VRID Virtual Router ID. Number that identifies the virtual router
on the LAN
