HSRP priority is a numeric value that influences which router becomes the active router in an HSRP group. The router with the highest priority wins; if priorities match, the router with the highest IP address wins. section 19.3
Making R1 active
With default priority 100, R2 at 10.0.0.3 would beat R1 at 10.0.0.2. Configure R1 with `standby 1 priority 105` to make it active. Add `standby 1 preempt` so R1 retakes the active role after recovering from a failure. section 19.3
Figure 19.7 An HSRPv2 group of two routers. R1 is the active router, and R2 is the standby. If R1 fails, R2 will become the active router. However, because preemption is enabled on R1, it will retake its role after it recovers from the failure.
Use the diagram to follow the active and standby roles during R1 failure and recovery. section 19.3
