Virtual routers are disabled by default.

The following table describes the Virtual Router Configuration Menu options.

Command

Description

 

 

track

Displays the VRRP Priority Tracking Menu for this virtual router. Tracking is a

 

proprietary extension to VRRP, used for modifying the standard priority system

 

used for electing the master router.

 

 

vrid <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 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 255. 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. The default address is 0.0.0.0

 

 

if <1-256>

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 disableenable

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.

 

 

ena

Enables this virtual router.

 

 

dis

Disables this virtual router.

 

 

del

Deletes this virtual router from the switch configuration.

 

 

cur

Displays the current configuration information for this virtual router.
