In which HSRP state is the router a candidate to become the next active router for the group?
The HSRP router in standby state (the standby router) is a candidate to become the next active HSRP router should the current active router fail.
The six HSRP states are defined as follows:
- Initial state: All routers start in this state.
- Learn state: The router is in the learn state when it has not communicated with the active router. It does not know which router is the active router and does not know the IP address of the virtual router (if no HSRP IP address configured in the router).
- Listen state: Once the router hears from the active router and knows the virtual IP address, it enters the listen state. It is not the active or standby router.
- Speak state: After a router learns the IP address of the virtual router, it enters the speak state. It participates in the active and standby router election. It sends hello messages to the active router.
- Standby state: When the active router has been elected, the second router enters the standby state. This is the standby router and it will become the active router if the active router fails.
- Active state: The router is in active state when it is forwarding packets. It receives packets via the virtual IP address.
Backup is not a valid HSRP router state.
