VRRP Virtual Router Configuration Options (continued)
Command Syntax and Usage
virtual­router <1‐128> next­hop <IP address> [arp|icmp]
[interval <1‐60>] [retry <1‐3>]
Defines the next‐hop IP address and tracking parameters. If not successful, the
command will retry the health check at regular intervals of the specified
number of seconds for the number of retries specified by retry.
Default values are icmp, 2 seconds and 3 retries.
Note: Up to 4 unique next‐hops can be configured for a virtual router. All 4
next‐hops will be tracked.
Command mode: Router VRRP
no virtual­router <1‐128> next­hop <IP address>
Removes the specified next‐hop IP address.
Command mode: Router VRRP
[no] virtual­router <1‐128> preemption [priority­only]
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 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.
If priority­only is specified, preemption is based on priority and the IP
address is disregarded.
Command mode: Router VRRP
virtual­router <1‐128> priority <1‐254>
Defines the election priority bias for this virtual server. 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.
The priority value can be any integer between 1 and 254. The default value is
100.
Command mode: Router VRRP
virtual­router <1‐128> 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.
