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.
The following table describes the Virtual Router Group Configuration Menu options.

Command
Description
track
Displays the VRRP Priority Tracking Menu for the virtual router group.
Tracking is a proprietary extension to VRRP, used for modifying the standard
priority system used for electing the master router.
vrid <1-250>
Defines the virtual router ID.
The vrid for standard virtual routers (where the virtual router IP address is
not the same as any virtual server) can be any integer between 1 and 250.
All vrid values must be unique within the VLAN to which the virtual
router‘s IP interface (see if below) belongs. The default virtual router ID is
1.
if <1-249>
Selects a switch IP interface. The default switch IP interface number is 1.
prio <1-254>
Defines the election priority bias for this virtual router group. 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 is 1.
preem disable|enable
Enables or disables master preemption. When enabled, if the virtual router
group 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 the virtual router group.
dis
Disables the virtual router group.
del
Deletes the virtual router group from the switch configuration.
cur
Displays the current configuration information for the virtual router group.
