After the tracked critical object fails to recover, the HSRP priority automatically reverts to its original value, so it can become the active router again by preemption.(9) HSRP states The HSRP state transition process goes through the following six states..254 . Cisco Networking Lab CCNA Lab Guide (Release 2).1 Initial (Initial) state: The state when HSRP is started, HSRP is not yet running, and is usually entered when the configuration is changed or the port is just started.2 Learn state: In this state, the router has not yet been given a virtual IP address and has not seen an authenticated Hello packet from the active router. The router is still waiting for a Hell. packet from the active router.3 Listen state: the router has been given the virtual IP address. it keeps listening for Hello packets from the active and backup routers. if no Hell packets are received for a period of time. it enters the Speak state and starts campaigning.4 Speak state: In this state, the router periodically sends Hello packets and is actively in the running for the active or backup router. If the active and backup routers have been elected then the listening state is returned, at which point only the active and backup routes are in the announce state.5 Backup (Standby) state: The router in this state is the next candidate for the active router, which sends Hello packets at regular intervals.6 Active state: A router in the active state takes on the task of forwarding packets to the group's virtual MAC address. It sends out Hello packets at regular intervals.15.2.2 Introduction to VRRP
