NETGEAR 8800 User Manual Table 56. VRRP Configuration Parameters (Continued) Parameter ip_address advertisement_interval skew_time master_down_interval preempt_mode preempt_timer track mode Description 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. For more information, see the configure vrrp vlan vrid add ipaddress command. Specifies the time interval between advertisements in seconds unless otherwise specified as milliseconds. The default is 1 second. The range is 1 through 255 seconds or 100 through 999 milliseconds. Note: If you must configure the range in milliseconds, specify the milliseconds keyword. If you enter a number from 100 through 255 and do not specify the milliseconds keyword, the interval defaults to seconds. For more information, see the configure vrrp vlan vrid advertisement-interval command. This is the time to skew master_down_interval, in seconds. This value is calculated as ((256-priority)/256). 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). 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. For more information, see the configure vrrp vlan vrid preempt or the configure vrrp vlan vrid dont-preempt commands. The preempt timer defines a preempt delay period for a preempting master. For more information, see the configure vrrp vlan vrid preempt command. The track option controls the behavior of the VRRP router when one of the tracked entities fails or comes back from failure. For more information, see the configure vrrp vlan vrid track-mode [all | any] command description. VRRP Tracking Tracking information is used to track various forms of connectivity from the VRRP router to the outside world. The following sections describe VRRP tracking options and how to display information on them: • VRRP Tracking Mode on page 588 • VRRP VLAN Tracking on page 588 • VRRP Route Table Tracking on page 588 • VRRP Ping Tracking on page 589 Chapter 19.
