Usage Information Example Dell EMC recommends keeping the default setting for this command. If you change the time interval between VRRP advertisements on one router, change it on all routers. The no version of this command sets the VRRP advertisements timer interval back to its default value, 1 second or 100 centisecs. OS10(conf-eth1/1/6-vrid-250)# advertise-interval 120 centisecs 100 Supported Releases 10.2.0E or later authentication-type Enables authentication of VRRP data exchanges.

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. 612 Layer 3
