Two routers, R1 and R2, share HSRP group 10 on a LAN. R1 is configured with priority 110 and R2 with the default priority. R1 was the active router until it rebooted, at which point R2 became active. Now that R1 has fully rebooted, network engineers notice R2 remains the active router even though R1 is online again. Which configuration on R1 would cause it to reclaim the active role automatically?
