Configuration Commands 128
VRRP Virtual Router Group configuration
The Virtual Router Group commands are 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 commands.
Table 153 Virtual Router Group Configuration commands
Command Description
group virtual-router-id
<1-255>
Defines the virtual router ID.
The
virtual router ID 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
virtual router ID values must be unique
within the VLAN to which the virtual router’s IP interface belongs. The default
virtual router ID is 1.
Command mode: Router VRRP
group interface <1-255> Selects a switch IP interface (between 1 and 255). The default switch IP
interface number is 1.
Command mode: Router VRRP
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.
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 except User EXEC
