Table 149 Virtual Router Configuration commands
Command
Description
virtual-router <1-250>
interface <1-249>
Selects a switch IP interface (between 1 and 250). If the IP interface has
the same IP address as the address option above, this switch is
considered the ―owner‖ of the defined virtual router. An owner has a
special priority of 255 (highest) and will always assume the role of
master router, even if it must preempt another virtual router which has
assumed master routing authority. This preemption occurs even if the
preemption option below is disabled. The default value is 1.
Command mode: Router VRRP
virtual-router <1-250>
priority <1-254>
Defines the election priority bias for this virtual server. This can be any
integer between 1 and 254. The default value is 100.
During the master router election process, the routing device with the
highest virtual router priority number wins. If there is a tie, the device
with the highest IP interface address wins. If this virtual router‘s IP
address is the same as the one used by the IP interface, the priority for
this virtual router will automatically be set to 255 (highest).
When priority tracking is used, this base priority value can be modified
according to a number of performance and operational criteria.
Command mode: Router VRRP
virtual-router <1-250>
timers advertise <1-255>
Defines the time interval between VRRP master advertisements. This
can be any integer between 1 and 255 seconds. The default value is 1.
Command mode: Router VRRP
[no] virtual-router <1-250>
preemption
Enables or disables master preemption. When enabled, if this virtual
router is in backup mode but has a higher priority than the current
master, this virtual router will preempt the lower priority master and
assume control. Note that even when preemption is disabled, this
virtual router will always preempt any other master if this switch is the
owner (the IP interface address and virtual router address are the
same). By default, this option is enabled.
virtual-router <1-250>
enable
Enables this virtual router.
Command mode: Router VRRP
no virtual-router <1-250>
enable
Disables this virtual router. This is the default.
Command mode: Router VRRP
no virtual-router <1-250>
Deletes this virtual router from the switch configuration.
Command mode: Router VRRP
show ip vrrp virtual-router
<1-255>
Displays the current configuration information for this virtual router.
Command mode: All
