Virtual Router Priority Tracking Configuration Menu
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 (see page 362).
Criteria are tracked dynamically, continuously updating virtual router priority levels when enabled.
If the virtual router pre-emption option (see preem in Table 200 on page 353) 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.

Command Syntax and Usage
vrs disable|enable
When enabled, the priority for this virtual router will be increased for each virtual router in
master mode on this switch. This is useful for making sure that traffic for any particular
client/server pairing are handled by the same switch, increasing routing and load balancing
efficiency. This command is disabled by default.
ifs disable|enable
When enabled, the priority for this virtual router will be increased for each other IP interface
active on this switch. An IP interface is considered active when there is at least one active port
on the same VLAN. This helps elect the virtual routers with the most available routes as the
master. This command is disabled by default.
