Virtual Router Configuration controls
Control Descriptions
IP Interface (1-249)
Selects a switch IP interface. If the IP interface has the same IP address as
the
addr
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
preem
option below is disabled. The default
value is 1.
Enabled?
Enables or disables this virtual router.
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
(
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.
Advertisement Interval (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.
Owner 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
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.
Track master virtual routers?
When enabled, the priority for this virtual router will be increased for each
virtual router in master mode on this switch. This is useful for making sure
that traffic for any particular client/server pairing are handled by the same
switch, increasing routing and load balancing efficiency. This command is
disabled by default.
Track other IP 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.
Track VLAN switch 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.
