#routerprotocol

HSRP is a Cisco proprietary protocol that provides redundancy for a local subnet. It does this by creating a virtual router that is made up of two or more physical routers. Only one router is active at a time, but if the active router fails, another router will immediately take over. This helps to ensure that network traffic continues to flow even if there is a router failure. https://www.dclessons.com/hsrp-concepts
