VRRP Virtual Router Group Configuration Options (continued)
Command Syntax and Usage
[no] group preemption
Enables or disables master pre‐emption. When enabled, if the virtual router
group is in backup mode but has a higher priority than the current master, this
virtual router will pre‐empt the lower priority master and assume control.
Note that even when preemption is disabled, this virtual router will always
pre‐empt any other master if this switch is the owner (the IP interface address
and virtual router address are the same).
The default setting is enabled.
Command mode: Router VRRP
group priority <1‐254>
Defines the election priority bias for this virtual router group. 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).
This can be any integer between 1 and 254. The default value is 100.
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 track
Enables the priority system used when electing the master router from a pool
of virtual router groups. To view command options, see page
Command mode: Router VRRP
group virtual­router­id <1‐255>
Defines the virtual router ID (VRID).
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 128. All
VRID values must be unique within the VLAN to which the virtual router's IP
interface (see interface) belongs.
The default virtual router ID is 1.
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.
