Connectivity Guide

authentication-type
Enables authentication of VRRP data exchanges.
Syntax
authentication-type simple-text password
Parameters
simple-text password — Enter a simple text password.
Default Disabled
Command Mode INTERFACE-VRRP
Usage Information With authentication enabled, OS10 ensures that only trusted routers participate in routing in an autonomous
network. The no version of this command disables authentication of VRRP data exchanges.
Example
OS10(conf-ethernet1/1/6-vrid-250)# authentication simple-text eureka
Supported Releases 10.2.0E or later
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 original master recovers or the new 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 or congure the VRRP group’s virtual IP address with same IP address as the interface’s
primary IP address. If you set the priority to 254 and the virtual-address is not equal to the interface’s
primary IP address, the system displays an error message. The no version of this command resets the value to the
default of 100.
