One router can assume the routing responsibility of another if a router goes out of commission for either planned or unplanned reasons. With HSRP, members of the virtual router group continually exchange status messages. This address is known as a default gateway. Most host workstations do not contain routing tables and use only a single next hop IP and MAC address. The address is necessary for host workstation default gateway redundancy. Two or more routers can act as a single, virtual router if they share an IP address and a MAC (Layer 2 ) address. HSRP, which is unique to Cisco platforms, provides network redundancy for IP networks in a manner that ensures that user traffic immediately and transparently recovers from first-hop failures in network edge devices or access circuits. Customers can satisfy their demands for near-100 percent network uptime if they leverage the HSRP in Cisco IOSВ® Software. Understand HSRP Background InformationД«usinesses and consumers that rely on intranet and Internet services for their mission-critical communications require and expect their networks and applications to be continuously available to them. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.

This document is not restricted to specific software and hardware versions. There are no specific requirements for this document. This document is not intended to be a design guide, software-recommendation document, or a best practices document. Nevertheless, the sole purpose of this document is to facilitate and guide engineers on who to troubleshoot HSRP.

The document contains many references to software versions and network topology design.

Note: This document details how to troubleshoot HSRP in Catalyst switch environments. Switch error messages that relate to HSRPД®xcessive network unicast flooding to the HSRP configuration Router report of a duplicate HSRP standby IP addressД¬onstant HSRP state changes ( active, standby, speak) This document covers these most-common issues that relate to HSRP: Instead, they are network problems that affect the behavior of HSRP. Most HSRP-related problems are not true HSRP issues. This document covers common issues and ways to troubleshoot HSRP problems.

Because of the nature of the Hot Standby Router Protocol (HSRP), specific network problems can lead to HSRP instability.
