Disable Preempt
The preempt command is enabled by default, and it forces the system to change the MASTER router if
another router with a higher priority comes online.
Prevent the BACKUP router with the higher priority from becoming the MASTER router by disabling
preempt.
Since preempt is enabled by default, disable the preempt function with the following command in the
VRRP mode. Re-enable preempt by entering the
preempt command. When preempt is enabled, it does not
display in the show commands, because it is a default setting.,
Command Example:
no preempt
FTOS(conf-if-gi-1/1)#vrrp-group 111
FTOS(conf-if-gi-1/1-vrid-111)#no preempt
FTOS(conf-if-gi-1/1-vrid-111)#show conf
Note: As shown in the following example, the VRRP authentication password that you configure is
displayed in encrypted form in show running-config (EXEC Privilege) and show config (INTERFACE)
command output. To display the VRRP authentication password (as well as all other FTOS passwords) in
clear text in show command output, you must enter the no service password-encryption
(CONFIGURATION) command. To remove the currently configured VRRP authentication password, enter
the no authentication-type simple [encryption-type] password command.
Note: All virtual routers in the VRRP group must be configured the same: all configured with preempt
enabled or configured with preempt disabled.
Task Command Syntax Command Mode
Prevent any BACKUP router with a higher priority from becoming the
MASTER router.
