Which configuration command can u apply to a HSRP router so that its local interface becomes active if all other routers in the group fail?
- no additional config is required
- standby 1 track ethernet
- standby 1 preempt
- standby 1 priority 250
Explanation: Simply because that will be the default behavior routers would follow in the event all other routers in the HSRP group fail, then it would not keep attributes such as priority or preemption.
What preemption does in summary is to make sure that the configured Priority on all routers within the same HSRP group is always respected. That is, if R1 is configured on the HSRP group with a priority of 150 but he stands as active since all other routers currently subscribed to that group have a priority 150, then will router will preempt the current active router and will take over hence becoming the new active router.
With preemption disabled, the new router does not preempt the current active router, unless routers in the group have to renegotiate their roles based on each router’s priority at the time of negotiation.
