Configuration Commands 126
VRRP Virtual Router configuration
Virtual Router commands are used for configuring up to 128 virtual routers for this switch. 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.
Virtual routers are disabled by default.
The following table describes the Virtual Router Configuration commands.
Table 151 Virtual Router Configuration commands
Command Description
virtual-router <1-255>
virtual-router-id <1-255>
Defines the virtual router ID. This is used in conjunction with addr (below) to
define a virtual router on this switch. To create a pool of VRRP-enabled routing
devices which can provide redundancy to each other, each participating VRRP
device must be configured with the same virtual router: one that shares the
same
virtual router ID and address combination.
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. The
default value is 1.
All
virtual router ID values must be unique within the VLAN to which
the virtual router’s IP interface belongs.
Command mode: Router VRRP
[no] virtual-router <1-255>
address <IP address>
Defines the IP address for this virtual router using dotted decimal notation. This
is used in conjunction with the
vrid (above) to configure the same virtual
router on each participating VRRP device. The default address is 0.0.0.0
Command mode: Router VRRP
virtual-router <1-255>
interface <1-255>
Selects a switch IP interface (between 1 and 255). If the IP interface has the
same IP address as the
address option above, this switch is considered the
“owner” of the defined virtual router. An owner has a special priority of 255
(highest) and will always assume the role of master router, even if it must
preempt another virtual router which has assumed master routing authority. This
preemption occurs even if the
preemption option below is disabled. The
default value is 1.
Command mode: Router VRRP
virtual-router <1-255>
priority <1-254>
Defines the election priority bias for this virtual server. 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
virtual-router <1-255>
timers advertise <1-255>
Defines the time interval between VRRP master advertisements. This can be any
integer between 1 and 255 seconds. The default value is 1.
Command mode: Router VRRP
[no] virtual-router <1-255>
preemption
Enables or disables master preemption. When enabled, if this virtual router 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.
virtual-router <1-255>
enable
Enables this virtual router.
Command mode: Router VRRP
no virtual-router <1-255>
enable
Disables this virtual router.
Command mode: Router VRRP
no virtual-router <1-255> Deletes this virtual router from the switch configuration.
Command mode: Router VRRP
