Now let's verify our basic lab configurations so we have a good foundation upon which to add our HSRP configuration.
Here we take a break for a brief overview of HSRP. These facts might be useful on your exam.
In this section we configure HSRP step-by-step, with full explanations for each step.
In this lesson we simulate a network failure that will force a fail-over event to occur, which should activate our HSRP configuration by making R-2 our primary gateway.
We conclude our work by repairing our network by replacing the link we deleted in the previous lesson. Then we run our show commands to verify that our HSRP and overall network's settings have been restored to our original configuration.
Thank you for taking my course. Check out the Build a Small business Network course to learn many configurations relative to CCNA and Network+ exam goals. Also, consider taking my Subnetting Lab course to learn all the address ranges and IANA regulations, plus the fastest 3-step subnet formula to save time on your exam. Thank you again for taking my course, and my best to you in your IT career.

In this course, you will learn one of the most important protocols for redundancy: HSRP, the Hot Standby Routing Protocol. It is called "hot standby" because the backup routers are powered on and are functioning as normal. But in the HSRP environment, only one router is the Active Gateway for its network.
This redundancy provides fail-over in case the primary gateway router malfunctions or otherwise becomes unavailable. As such, this course is vital to anyone wanting to pass their CCNA, CCNP, or Network+ certification exams, because redundancy is an important part of network engineering.
Plus I will teach you something most other instructors do not teach: I will teach you how to test your HSRP environment by intentionally disabling the network, step-by-step, so you understand how everything works.
This course includes:
How to set up a lab in Packet-Tracer
How to assign static IPv4 addresses
Creating two contiguous subnetworks to be our LANs
How to assign a default gateway to a LAN
How to verify (test) your configurations
How to configure the Hot Standby Routing Protocol on multiple routers and LANs
What a virtual gateway IP address is and how to create it
How to verify (test) your HSRP configurations
New specific HSRP show commands that may appear on your exam
How to test HSRP by intentionally disabling part of the network
Two quizzes to test your knowledge
A review of HSRP's key features
This course also includes a FREE copy of my book "On the Command Line" featuring 100 of the most common configurations you will encounter in the real world of network engineering, and often found on the CCNA, CCNP, and Network+ exams.
