Why should I take this module?

Welcome to FHRP Concepts!

Your network is up and running. You’ve conquered Layer 2 redundancy without any Layer 2 loops. All your devices get their addresses dynamically. You are good at network administration! But, wait. One of your routers, the default gateway router in fact, has gone down. None of your hosts can send any messages outside of the immediate network. It’s going to take a while to get this default gateway router operating again. You’ve got a lot of angry people asking you how soon the network will be ‘back up.’

You can avoid this problem easily. 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). You will learn how HSRP works and then complete a Packet Tracer activity where you will configure and verify HSRP. Don’t wait, get started!
