Table 153 Virtual Router Group Configuration Menu options Command track vrid if prio adver preem disable|enable ena dis del cur Description 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. 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 255. 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. Selects a switch IP interface. The default switch IP interface number is 1. 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. Defines the time interval between VRRP master advertisements. This can be any integer between 1 and 255 seconds. The default is 1. 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. Enables the virtual router group. Disables the virtual router group. Deletes the virtual router group from the switch configuration.

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.
Table 153
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 <
1-255
>
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 255. 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 <
1-256
>
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.
