By: Lazaro (Laz) Diaz

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. By the end of this book, you will explore security best practices, as well as get familiar with the protocols that a network administrator can use to monitor the network.

Configuring IPv6 routing

For the following IPv6 configurations, we will be using the following simple topology:

We have five networks, three LANs, and two WANs. You can see the IPv6 addressing scheme that we are using. The IPv6 addresses that you see are only the network prefix with the prefix length, so we are going to put those IPv6 addresses manually on the routers and PCs.

Let's start with the PCs and then move to the routers. I personally like to assign the IP addresses first, test for basic connectivity, and then dive deep and start the routing configurations:

The IPv6 addresses that you see are the ones that I assigned. I am using the rule of zero. If we do not do that, then we would have to type the following:

2001:4800:FACE:1000:0000:0000:0000:0001

Not happening! So, I took out all the leading zeros.

As mentioned in the previous chapter, the interface ID does not...
