2019年3月29日 · This chapter describes how to use Hot Standby Router Protocol (HSRP) to provide routing redundancy for routing IP traffic without being dependent on the availability of any single router. You can also use a version of HSRP in Layer 2 mode to configure a redundant command switch to take over cluster management if the cluster command switch fails.

2010年10月10日 · In this article we will discuss two different network scenarios where HSRP can be used to provide redundancy between two paths from an internal LAN network towards the outside world (WAN or Internet). Let’s see a diagram …

2025年2月13日 · The Hot Standby Router Protocol (HSRP) is a First Hop Redundancy Protocol (FHRP) designed to allow 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.

2023年9月14日 · HSRP 全称为 热备份路由选择协议 （Hot Standby Routing Protocol，）是 Cisco（思科）私有的一种技术，HSRP确保了当网络边缘设备或接入链路出现故障时，用户通信能迅速并透明地恢复，以此为IP网络提供冗余性。 通过应用HSRP，可使网络的正常运行时间接近100%，从而满足用户对网络可靠性的要求。 HSPR协议的作用就是 提高网络的可用性，当网络边缘设备或接入链路出现故障时，HSRP协议可以自动切换到备用路由器，从而确保网络的正常 …

2023年9月13日 · One way to achieve near-100 percent network uptime is to use HSRP, which provides network redundancy for IP networks, and ensures that user traffic immediately and transparently recovers from first hop failures in network edge devices or access circuits.

Hot Standby Router Protocol or HSRP is a Cisco proprietary first hop redundancy protocol that is used to configure default gateway redundancy. With HSRP (like other gateway redundancy protocols), two or more routers can achieve default gateway failover in the event that the primary gateway fails or becomes inaccessible.

HSRP is a virtual gateway protocol for Cisco devices, in this lesson you will learn how it works and how to configure it.

HSRP is a Cisco proprietary redundancy protocol that allows failover of the next-hop IP device. It operates with an Active-Standby Model where only one device is supporting end-user traffic at any time, and the other device is on standby waiting to take over should the active device fails.

2021年10月25日 · Hot Standby Router Protocol (HSRP) is a CISCO proprietary protocol, which provides redundancy for a local subnet. In HSRP, two or more routers gives an illusion of a virtual router. HSRP allows you to configure two or more routers as standby routers and only a single router as an active router at a time.

In computer networking, the Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway. Version 1 of the protocol was described in RFC 2281 in 1998. Version 2 of the protocol includes improvements and supports IPv6 but there is no corresponding RFC published for this version.
