What does FHRP Object Tracking allow you to monitor?

FHRP (First Hop Redundancy Protocol) Object Tracking is a feature that enhances the functionality of redundant gateway protocols like HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), and GLBP (Gateway Load Balancing Protocol). The primary purpose of FHRP Object Tracking is to monitor the status of specific objects or conditions that can impact the priority assigned to a router in an active/standby configuration.

By utilizing Object Tracking, network devices can dynamically adjust their priority based on the state of the tracked objects. For example, if a tracked interface goes down, it can lower the priority of the router, causing the redundancy protocol to promote another router to become the active device. This ensures that the most capable and responsive device remains active, thus enhancing network reliability and availability.

In contrast, monitoring physical hardware status, router uptime, and connection speed metrics generally pertains to broader device performance and health, rather than the specific decision-making process of FHRP in terms of which router should take active duty based on real-time conditions affecting traffic flow.
