Table 151 Virtual Router Group Configuration commands
Command
Description
group priority <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 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, this base priority value can be modified
according to a number of performance and operational criteria.
Command mode: Router VRRP
group advertisement <1-255>
Defines the time interval between VRRP master advertisements. This
can be any integer between 1 and 255 seconds. The default is 1.
Command mode: Router VRRP
[no] group preemption
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 preemption is disabled,
this virtual router will always preempt any other master if this switch is
the owner (the IP interface address and virtual router address are the
same). By default, this option is enabled.
Command mode: Router VRRP
group enable
Enables the virtual router group.
Command mode: Router VRRP
no group enable
Disables the virtual router group. This is the default.
Command mode: Router VRRP
no group
Deletes the virtual router group from the switch configuration.
Command mode: Router VRRP
show ip vrrp group
Displays the current configuration information for the virtual router
group.
Command mode: All
VRRP Virtual Router Group Priority Tracking configuration
The following table describes the Virtual Router Group Priority Tracking Configuration commands.
Table 152 Virtual Router Group Priority Tracking Configuration commands
Command
Description
[no] group track interfaces
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.
Command mode: Router VRRP
[no] group track ports
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.
Command mode: Router VRRP
show ip vrrp group track
Displays the current configuration for priority tracking for this virtual
router.
Command mode: All
NOTE: If Virtual Router Group Tracking is enabled, then the tracking option will be available only
under group option. The tracking setting for the other individual virtual routers is ignored.
