We have a large enterprise network and our routers and switches are running HRSP. We were told the preempt command should be added to the interface of both the primary and the standby router. We have checked our configuration and notice that the preempt command is only on the primary routers. My question is if we configuer the priorty command to set a primary router and a standby router, does the priorty statement have any control on which router will be the primary after a failuer and recovery? if not when the preempt command is only on the router with the higest priorty will the standby router reinstate control to the primary after a failuer and recovery of the router with the higest priorty?
I am asking this question now so if configuration changes are needed on our network I would like to do them now before any outages. Thank you all for your responses.
