What is IPv6, and why is it needed? In this course, IT trainer and a technology advocate Jarrel Rivera guides you through what you need to know about this network layer protocol so you can better manage your network. Learn about types of IPv6 addresses and how to shorten them. Go over how to use IPv6 in Windows clients and Linux clients, as well as how to dual stack with IPv6. Plus, explore what you can do with Dynamic IPv6 via SLAAC, EUI-64, DHCPv6, and Cisco IOS.

The Domain Name System (DNS) helps us whenever we browse the internet by translating domain names that are easy for humans to read into IP addresses. In this introductory course, IT trainer and technology advocate Jarrel Rivera guides you through the basics of what DNS is, what it does, and how to manage it. Learn about DNS domain hierarchy, name resolution, and record types. Explore more advanced topics like DNS query packet analysis, caching, forwarding and security. Discover effective ways… Show more

Cisco Modeling Labs is an on-premises network simulation tool that runs on workstations and servers. With Cisco Modeling Labs, you can quickly and easily simulate Cisco and non-Cisco networks, using real Cisco images. This gives you highly reliable models for designing, testing, and troubleshooting. In this course, Jarrel Rivera helps networking and IT pros practice, design, test, and troubleshoot network models— without the cost or inherent risks of testing in existing networks.

Border gateway protocol—or BGP, for short—is the primary routing protocol that’s used to exchange networks and manage traffic on the internet. You might already know what BGP is, or even how to effectively configure it. But if you’re looking to learn more about advanced techniques, this course was designed just for you.

Learn the fundamentals of Border Gateway Protocol (BGP)—the only exterior routing protocol used to exchange networks on the Internet—and learn how to configure it. Join instructor Jarrel Rivera as he shows you what BGP is all about, how it differs from other routing protocols, its various parameters, and how you can configure and apply BGP to your network. Jarrel also runs a number of BGP demonstrations, so you can see the lessons in action as you go along.

Explore the basics of the Routing Information Protocol (RIP), before turning to the Enhanced Interior Gateway Routing Protocol (EIGRP), a more advanced distance-vector protocol for network route configuration. Along the way, Jarrel provides step-by-step demos using IPv4 and IPv6 addresses. By the end of this course, you’ll have the skills you need to leverage RIP and EIGRP so you can get the most out of your network topology.

OSPF, or Open Shortest Path First, is one of the most widely-used routing protocols in the world, and it brings many features and great flexibility to your network. In this course, Jarrel Rivera takes a look at what OSPF is all about, how it differs from other routing protocols, and discusses its various parameters to show you how to configure and apply OSPF to your network. This course will also give you practice configuring all of these protocols using the Cisco Modeling Labs demo environment.
