HP BMD00022 manual Vrrp Virtual Router Priority Tracking configuration, Preem disableenable

Table 162 Virtual Router Configuration Menu options

Command	Description
prio <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 (addr) 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 (/cfg/l3/vrrp/track or
	/cfg/l3/vrrp/vr #/track), this base priority value can be modified
	according to a number of performance and operational criteria.
adver <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.
preem disableenable	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 preem is disabled, this virtual router will always preempt any
	other master if this switch is the owner (the IP interface address and virtual
	router addr are the same). By default, this option is enabled.
ena	Enables this virtual router.
dis	Disables this virtual router.
del	Deletes this virtual router from the switch configuration.
cur	Displays the current configuration information for this virtual router.

VRRP Virtual Router Priority Tracking configuration

Command: /cfg/l3/vrrp/vr <1-250>/track

[VRRP Virtual	Router 1 Priority Tracking Menu]
vrs	- Enable/disable tracking master virtual routers
ifs	- Enable/disable tracking		other interfaces
ports	-	Enable/disable tracking	VLAN	switch ports
cur	-	Display current VRRP virtual		router configuration

This menu is used for modifying the priority system used when electing the master router from a pool of virtual routers. Various tracking criteria can be used to bias the election results. Each time one of the tracking criteria is met, the priority level for the virtual router is increased by an amount defined through the VRRP Tracking Menu.

Criteria are tracked dynamically, continuously updating virtual router priority levels when enabled. If the virtual router preemption option is enabled, this virtual router can assume master routing authority when its priority level rises above that of the current master.

Some tracking criteria (vrs, ifs, and ports below) apply to standard virtual routers, otherwise called virtual interface routers. A virtual server router is defined as any virtual router whose IP address (addr) is the same as any configured virtual server IP address.
