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 165 Virtual Router Priority Tracking Configuration Menu options

Command

Description

 

 

vrs disableenable

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 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 virtual router ID and an IP address. On each VRRP-capable routing device participating in redundancy for this virtual router, a virtual router will be configured to share the same virtual router ID and IP address.
