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.

The following table describes the Virtual Router Priority Tracking Configuration Menu options.

Table 152 Virtual Router Priority Tracking Configuration Menu options

Command

Description

 

 

vrs disableenableWhen 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 disableenable

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.

 

 

ports disableenable

When enabled, the priority for this virtual router will be increased for each

 

active port on the same VLAN. A port is considered “active” if it has a link and

 

is forwarding traffic. This helps elect the virtual routers with the most available

 

ports as the master. This command is disabled by default.

The Virtual Router Group menu is used for associating all virtual routers into a single logical virtual router, which forces all virtual routers on the switch to either be master or backup as a group. A virtual router is defined by its
