Which First Hop Redundancy Protocol is described as non-proprietary, open-source, and widely used?

First Hop Redundancy Protocols keep the default gateway reachable if the primary router fails by allowing multiple routers to participate and electing a master to forward traffic, with backups ready to take over. Among protocols, the one that is non-proprietary, open, and widely used is VRRP. It’s an IETF-standardized protocol (defined in RFC 5798) that enables multi-vendor interoperability, so many different routers can work together seamlessly in diverse networks. This broad adoption is why VRRP is favored in environments that want to avoid vendor lock-in and ensure gateway redundancy across devices from different manufacturers. In contrast, HSRP and GLBP are Cisco-proprietary solutions, and FHRP is the general family name for these protocols rather than a specific open standard.
