preempt
Permits or preempts a backup router with a higher priority value to become the master router.
Syntax
preempt
Parameters None
Default Enabled
Command Mode INTERFACE-VRRP
Usage Information VRRP uses preempt to determine what happens after a VRRP backup router becomes the master. With preempt
enabled by default, VRRP switches to a backup if that backup router comes online with a priority higher than the
new master router. If you disable preempt, VRRP switches only if the master fails. The no version of this command
disables preemption.
Example
OS10(conf-eth1/1/5-vrid-254)# preempt
Supported Releases 10.2.0E or later
priority
Assigns a VRRP priority value for the VRRP group. The VRRP uses this value during the master election process.
Syntax
priority number
Parameters number — Enter a priority value, from 1 to 254.
Default 100
Command Mode INTERFACE-VRRP
Usage Information To guarantee that a VRRP group becomes master, congure the priority of the VRRP group to the 254, which is
the highest priority. OS10 does not support priority 255. The no version of this command resets the value to the
default of 100.
Example
OS10(conf-eth1/1/5-vrid-254)# priority 200
Supported Releases 10.2.0E or later
