Table 34: VRRP Configuration Parameters
Parameter Description
vrid Virtual router identifier. Configured item in the range of 1- 255. This
parameter has no default value.
priority Priority value to be used by this VRRP router in the master election
process. A value of 255 is reserved for a router that is configured with
the virtual router IP address. A value of 0 is reserved for the master
router to indicate it is releasing responsibility for the virtual router. The
range is 1 - 254. The default value is 100.
ip_address One or more IP addresses associated with this virtual router. This
parameter has no default value.
advertisement_interval Time interval between advertisements, in seconds. The range is 1 -
255. The default value is 1 second.
skew_time Time to skew master_down_interval, in seconds. This value is
calculated as ((256-priority)/256).
master_down_interval Time interval for backup router to declare master down, in seconds.
This value is calculated as
((3 * advertisement_interval) + skew_time).
preempt_mode Controls whether a higher priority backup router preempts a lower
priority master. A value of true allows preemption. A value of false
prohibits preemption. The default setting is true.
NOTE
The router that owns the virtual router IP address always
preempts, independent of the setting of this parameter.
