VRRP Virtual Router Group Configuration Options (continued)
Command Syntax and Usage
group interface <interface number (1‐126)>
Selects a switch IP interface.
The default switch IP interface number is 1.
Command mode: Router VRRP
group interface <interface number (1‐126)> restricted
Enables restricted VRRP control traffic on an interface. When enabled, the
VRRP control messages can be sent to a dedicated interface only. This helps
preventing control messages from being dropped.
Command mode: Router VRRP
group preempt­delay­time <0‐255>
Configures the preempt delay interval (in seconds). This timer is configured
on the virtual router group and prevents the switch from transitioning back to
Master state until the preempt delay interval has expired. Ensure that the
interval is long enough for OSPF or other routing protocols to converge.
The default value is 0 seconds.
Command mode: Router VRRP
[no] group preemption [priority­only]
Enables or disables master pre‐emption. When enabled, if the virtual router
group is in backup mode but has a higher priority than the current master, this
virtual router will pre‐empt 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 address are the same).
The default setting is enabled.
If priority­only is specified, preemption is based on priority and the IP
address is disregarded.
Command mode: Router VRRP
group priority <1‐254>
Defines the election priority bias for this virtual router group. 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).
This can be any integer between 1 and 254. The default value is 100.
When priority tracking is used, this base priority value can be modified
according to a number of performance and operational criteria.
