Virtual Router Priority Tracking Configuration Menu
This menu is used for modifying the priority system used when electing the primary 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 (see /cfg/l3/vrrp/track VRRP Tracking Configuration).
Criteria are tracked dynamically, continuously updating virtual router priority levels when enabled. If the virtual router preemption option (see preem in /cfg/l3/vrrp/group/track Virtual Router Group Priority Tracking Configuration) is enabled, this virtual router can assume primary routing authority when its priority level rises above that of the current primary.
Some tracking criteria (such as vrs, ifs, and ports) apply to standard virtual routers (virtual interface routers). Other tracking criteria (such as l4pts, reals, and hsrp) apply to virtual server routers, which perform Layer 4 Server Load Balancing functions. A virtual server router is defined as any virtual router whose IP address (addr) is the same as any configured virtual server IP address.

VRRP Priority Tracking Menu Options (/cfg/l3/vrrp/vr/track) 
Command Syntax and Usage
vrs disable|enable
 
When enabled, the priority for this virtual router is increased for each virtual router in primary mode on this Alteon. This is useful for ensuring that traffic for any particular client/server pairing is handled by the same Alteon, increasing routing and load balancing efficiency.
Default: disable
ifs disable|enable
 
When enabled, the priority for this virtual router is increased for each IP interface active on this Alteon. An IP interface is considered active when there is at least one active port on the same VLAN.
Helps elect the virtual routers with the most available routes as the primary server. An IP interface is considered active when there is at least one active port on the same VLAN. This parameter influences the VRRP router’s priority in both virtual interface routers and virtual server routers. Can also be used with LACP trunks.
Default: disable
ports disable|enable
 
When enabled, the priority for this virtual router is increased for each active port on the same VLAN. A port is considered active if it has a link and is forwarding traffic.
Helps elect the virtual routers with the most available ports as the primary router. This parameter influences the VRRP router’s priority in both virtual interface routers and virtual server routers.
Default: disable
l4pts disable|enable
 
When enabled for virtual server routers (VSRs) and virtual interface routers (VIRs), the priority for this virtual router is increased for each physical port which has active Layer 4 processing on this Alteon.
Helps elect the main Layer 4 Alteon as the primary server. This parameter influences the VRRP router’s priority in both virtual interface routers and virtual server routers. Can also be used with LACP trunks.
Default: disable
reals disable|enable
 
When enabled for virtual server routers, the priority for this virtual router is increased for each healthy real server behind the virtual server IP address of the same IP address as the virtual router on this Alteon.
Helps elect the Alteon with the largest server pool as the primary server, increasing Layer 4 efficiency. This parameter influences the VRRP router’s priority in virtual server routers only.
Default: disable
hsrp disable|enable
 
The Hot Standby Router Protocol (HSRP) is used with some types of routers for establishing router failover. In networks where HSRP is used, enable this option to increase the priority of this virtual router for each Layer 4 client-only port that receives HSRP advertisements.
Helps elect the Alteon closest to the primary HSRP router as the primary server, optimizing routing efficiency. This parameter influences the VRRP router’s priority in both virtual interface routers and virtual server routers.
Default: disable
hsrv disable|enable
 
A Hot-Standby Router on VLAN (HSRV) is used to work in VLAN-tagged environments.
Enable this option to increment only that VRRP instance that is on the same VLAN as the tagged HSRP primary flagged packet.
Default: disable
cur
 
Displays the current configuration for priority tracking for this virtual router.
