Table 153 VRRP Configuration Menu options
Command
Description
track
Displays the VRRP Priority Tracking Menu for this virtual router.
vrid <1-250>
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 vrid and addr 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 250.
The default value is 1.
All vrid values must be unique within the VLAN to which the virtual
router‘s IP interface belongs.
addr <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.
if <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.
prio <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.
adver <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.
preem disable|enable
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 pre-
empt 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.
ena
Enables this virtual router.
dis
Disables this virtual router. This is the default.
del
Deletes this virtual router from the switch configuration.
cur
Displays the current configuration information for this virtual router.
