Overview of this book

Cisco Certified Network Associate (CCNA) Routing and Switching is one of the most important qualifications for keeping your networking skills up to date. CCNA Routing and Switching 200-125 Certification Guide covers topics included in the latest CCNA exam, along with review and practice questions. This guide introduces you to the structure of IPv4 and IPv6 addresses and examines in detail the creation of IP networks and sub-networks and how to assign addresses in the network. You will then move on to understanding how to configure, verify, and troubleshoot layer 2 and layer 3 protocols. In addition to this, you will discover the functionality, configuration, and troubleshooting of DHCPv4. Combined with router and router simulation practice, this certification guide will help you cover everything you need to know in order to pass the CCNA Routing and Switching 200-125 exam.

Summary

In this chapter, we learned about the IPv6 routed protocol. We learned a little history about IP and how it benefits us, by creating a true hierarchy of IPv6 networks, which will allow our backbone or internet routers' routing table, to become more streamlined and efficient.

We also learned that IPv6 is a giant IP address, and that it is in hex format. But thanks to the powers that be, they gave us a way to express the IPv6 address in a lot shorter way by using the leading zero rule, but don't forget you can only have one double colon in an IPv6 address.

We also took the time to dive deep into the header of IPv6 and ICMPv6 and explain how important ICMPv6 is and the role that it plays in our network. We also delved into the autoconfiguration commands and saw how they work, if we want to be lazy with our configurations. Just keep in mind that with autoconfiguration...
