VRRP Configuration Parameters
Table 64 lists the parameters that you configure on a VRRP router.
Table 64: VRRP configuration parameters
Parameter Description
vrid This is the virtual router identifier and is a configured item in the
range of 1- to 255. This parameter has no default value.
priority This 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 to 254. The default value is 100.
ip_address This is the IP address associated with this virtual router. You can
associate one or more IP addresses to a virtual router. This parameter
has no default value.
advertisement_interval This is the time interval between advertisements, in seconds. The
range is 1 to 255. The default value is 1 second.
skew_time This is the time to skew master_down_interval, in seconds. This value
is calculated as ((256-priority)/256).
master_down_interval This is the time interval for the backup router to declare master down,
in seconds. This value is calculated as
((3 * advertisement_interval) + skew_time).
preempt_mode This controls whether a higher priority backup router preempts a lower
priority master. A value of true allows preemption, and 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.
