• Active – This is the state of the device that is actively forwarding traffic.
• Init or Disabled – This is the state of a device that is not yet ready or able to participate in HSRP.
• Learn – This is the state of a device that has not yet determined the virtual IP address and has not yet seen a hello message from an active device.
• Listen – This is the state of a device that is receiving hello messages.
• Speak – This is the state of a device that is sending and receiving hello messages.
• Standby – This is the state of a device that is prepared to take over the traffic forwarding duties from the active device.
