Explanation

In HSRP (Hot Standby Router Protocol), the active router is first determined by the configured priority value (default 100). When two routers have equal priority - which is the case here since no custom priority is shown - the tiebreaker is the highest IP address on the HSRP-enabled interface for that group. The highest MAC address, interface bandwidth, and boot order are not HSRP tiebreaker criteria. This is a fundamental HSRP election rule defined in RFC 2281.
