Hot Standby Router Protocol (HSRP)
Save
Hot Standby Router Protocol (HSRP) is a routing protocol that is used to provide redundancy and load balancing in IP networks. It is typically used to create a highly available default gateway and to prevent a single point of failure in a network. HSRP is a Cisco proprietary protocol and it can be used with any routing device that supports the Cisco IOS operating system.
How HSRP Works
HSRP works by creating a virtual router that is made up of two or more physical routers. Each physical router is configured with the same virtual router ID and the same IP address. The virtual router has a single MAC address that is used to identify the router to other devices on the network. When a router is elected as the active router, it will forward traffic for the virtual router. If the active router fails, the standby router will become the active router and will take over forwarding traffic.
Benefits of HSRP
There are several benefits to using HSRP in a network. Some of the benefits include:

Benefits of HSRP
There are several benefits to using HSRP in a network. Some of the benefits include:
- Provides redundancy. HSRP provides redundancy by creating a backup router that can take over if the active router fails. This helps to ensure that there is no single point of failure in the network.
- Improves load balancing. HSRP can be used to load balance traffic across multiple routers. This helps to improve performance and reduce congestion on the network.
- Easy to configure. HSRP is relatively easy to configure. It can be configured using the Cisco IOS command line interface (CLI).
