authentication-type Enables authentication of VRRP data exchanges. Syntax Parameters authentication-type simple-text password 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 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, configure 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 690 Layer 3
