First Hop Redundancy provides high availability of network gateways through redundant ____________?

First Hop Redundancy protocols create a single gateway the hosts can use, backed by multiple routers. The gateway IP is shared in a group of devices so that there’s always a functioning first hop for packets. One router is active at a time and answers traffic for that virtual gateway IP; if it fails, a standby router takes over immediately, preserving connectivity. That’s why redundancy focuses on the IP gateway—the virtual gateway address used by hosts—rather than the other devices. Access Points and Firewalls can be gateways in some setups, but the mechanism described by First Hop Redundancy is the redundant gateway IP provided by a group of routers.
