Explanation
In a looped triangle design, access switches connect to two distribution switches, creating redundant uplinks. Because hosts use a single default gateway IP address, a First Hop Redundancy Protocol (FHRP) such as HSRP, VRRP, or GLBP must be configured on the distribution switches to provide a virtual gateway IP. If one distribution switch fails, the FHRP ensures the other takes over as the active gateway without any manual reconfiguration on end devices. Without an FHRP, hosts would lose their default gateway when one distribution switch fails.
