Hot Standby Routing Protocol, a proprietary protocol from Cisco. HSRP is a routing protocol that provides backup to a router in the event of failure. Using HSRP, several routers are connected to the same segment of an Ethernet, FDDI or token-ring network and work together to present the appearance of a single virtual router on the LAN. The routers share the same IP and MAC addresses, therefore in the event of failure of one router, the hosts on the LAN are able to continue forwarding packets to a consistent IP and MAC address. The process of transferring the routing responsibilities from one device to another is transparent to the user.
Hot Standby Router ProtocolHSRP s a standard method in CISCO thatroutes the IP traffic without relying on the availability of any single router by providing high network availability by first-hop redundancy for IP hosts configured with default gateway IP.
Hot Standby Routing Protocol is a frist hope redandancy protocol own by CISCO. Practically it runs on the network to provide the high availabilty towards the network by setting up Gateway for BYOD.
Hot Standby Router Protocol (HSRP)
Is a routing protocol devolped by cisco that allows hosts computers on the internent to use muliple routers that act as a single virtual router, maintaining connectivity even if the first hop fails.
the Hot Standby Router Protocol (HSRP) is a cisco priority redundancy protocol for establishing a fault-tolerant default gateway
Hot Standby Router Protocol is cisco propriety protocol that provides a redundant gateway for host on a local subnet, is not a load-balance solution.
a protocol to support high availability system, with almost 100% uptime
HSRP, or the Hot Standby Routing Protocol, is a Cisco proprietary protocol that brings routing functionality to end devices that would otherwise not be capable of taking advantage of redundant network connections. HSRP enables a pair of Cisco routers to work together to present the appearance of a single virtual default-gateway to end devices on a LAN segment.
Often one of the best or least redundant part of a network is the first hop between a host and the rest of the network. If this device fails, then all of the users who are on a specific segment using it as their default gateway will be unable to reach any other subnet including the Internet.
There are a number of different solutions to this problem, and most of these are all grouped together and referred to as First Hop Redundancy Protocols (FHRP). Cisco recommend Hot Standby Redundancy Protocol (HSRP), which Cisco developed several years ago when no other standardized solution was existed.
Use of HSRP in CISCO
One way to achieve near-100 percent network uptime is to use HSRP, which provides network redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from first hop failures in network edge devices or access circuits.
The general idea behind HSRP is rather simple: Configure multiple devices that all exist on the same subnet and are able to act as gateways to the hosts on the subnet. Basic redundancy can be configured by configuring some of the hosts to use one gateway and the other hosts to use another
