What is not true about HSRP?

 EXPLANATION

Hot Standby Router Protocol (HSRP) is a Cisco proprietary routing protocol that allows host computers on the Internet to use multiple routers that act as a single virtual router, maintaining connectivity even if the first hop router fails, because other routers are on "hot standby" - ready to go. HSRP's preempt has to be manually set with the "standby vlan-number preempt" command in the Vlan interface configuration mode.
