First Hop Redundancy Protocol (FHRP) is a hop redundancy protocol that is designed to provide redundancy to the gateway router within the organization’s network by the use of a virtual IP address and virtual MAC address. To implement FHRP, there should be two or more routers that will be used as a gateway router.

2016年2月16日 · Perform this task to configure multiple HSRP groups for load balancing. Multiple HSRP groups enable redundancy and load-sharing within networks and allow redundant devices to be more fully utilized. A device actively forwarding traffic for one HSRP group can be in standby or in the listen state for another group.

2023年7月3日 · 第一跳冗余协议（fhrp）是确保网络冗余和高可用性的关键组成部分。在本文中，我们详细介绍了三种常见的fhrp协议：hsrp、vrrp和glbp。它们都通过将多个路由器组成一个冗余组，提供默认网关的冗余功能。

2022年10月7日 · As the name suggests it is a redundancy protocol that manages multiple gateway routers, i.e., it automatically replaces a failed gateway router with a functional backup (redundant) gateway router. FHRP is a not single protocol in general, but a class of protocols that provide similar functions: GLBP – Gateway Load Balancing Protocol.

First Hop Redundancy Protocol (FHRP) IP routing redundancy is designed to allow for transparent fail-over at the first-hop IP router. Both HSRP and VRRP enable two or more devices to work together in a group, sharing a single IP address, the virtual IP address.

The Hot Standby Router Protocol (HSRP) is a First Hop Redundancy Protocol (FHRP) designed to allow for transparent failover of the first-hop IP device. HSRP provides high network availability by providing first-hop routing redundancy for IP hosts on networks configured with a default gateway IP address.

What is an FHRP? FHRPs allow two or more physical devices to operate as redundant default gateways. If one physical device fails, the other takes over, and the hosts are none the wiser. The key to FHRPs is that they create what is known as a “virtual IP address” that is used as the address of the default gateway on the hosts.

2020年6月4日 · First Hop Redundancy Protocols (FHRPs) are the solution you need. This module discusses what FHRP does, and all of the types of FHRPs that are available to you. One of these types is a Cisco-proprietary FHRP called Hot Standby Router Protocol (HSRP).

2025年1月16日 · This tutorial explains basic concepts and options of the First Hop Redundancy Protocol. Learn what the Layer 3 redundancy is and how FHRP provides redundancy.

2018年5月8日 · HSRP is a Cisco proprietary FHRP, which uses groups, that contain active and standby routers to create a virtual gateway IP. If a router fails the standby router is promoted to active and takes ownership of the virtual gateway IP. Below details some further components and features of HSRP:
