HSRP, or Hot Standby Router Protocol, is a Cisco-proprietary protocol that provides redundancy and load balancing for IP networks. It allows multiple routers to share a single IP address, and if one router fails, another router can immediately take over without any interruption in service.
Checking the status of your HSRP configuration is important to ensure that your network is operating properly. There are a few different ways to check the status of HSRP, including using the “show standby” command in the Cisco IOS command-line interface (CLI).
