Main Lab

Overview

For this lab I worked in Packet Tracer to familiarize myself and learn how to configure IPv6. Objectives:

• Observe the use of Link-Local Addresses with IPv6
• Basic configuration of a router to support IPv6

Part 1 - Pre-Configuration

I began the lab by downloading the Packet Tracer file provided in the canvas shell. The file contains a very barebones network layout. I started by taking a look at the IP configuration window for PC1, noting the Link Local Address.

You can tell that this is a link local address as it starts with the prefix FE80 and it ends with the MAC Address of PC1. After this I copied the link local address of PC1 and went to the terminal for PC2 and successfully pinging the link local address with the command FE80::230:F2FF:FEE0:C627

After confirming that the link local address works for pinging on the local network it was time to move onto configuring the router.

Part 2 - Configuring the Router

In order to configure the router I first had to designate two different subnets for each interface of my router. In my case I used the IPV6 address of 2001:0DB8:AAAA:000A:0000:0000:0000:0001 for my Gig0/0 Interface. The 000A byte represents the bytes available for subnetting, the 2001:0DB8 bytes are the internet registry part of the address. This IPv6 Address can be simplified to just 2001:DB8:AAAA:000A::1 by removing the leading zeros, and condensing the other zeros in the bytes to two colons. With this format in mind I could subnet 2001:DB8:AAAA:000B::1 to the Gig0/1 interface. I also need a subnet mask of /64. After determining this it was time to configure the router itself. I did this going to the router's CLI and and using the following commands

enable

conf t

int g0/0

ipv6 address 2001:DB8:AAAA:000A::1/64

no shut

I then repeated this with the G0/1 interface.

With both sides of my router configured, I could move onto configuring the IPv6 for the PCs on the network

Part 3 - PC Configuration

I began configuring the IPv6 addresses for the PCs by going into the IP configuration window, and setting them to automatic rather than static. I had an issue where I was not receiving automatic IPv6 addresses. After some Googling I found that using the command ipv6 unicast-routing in my routers config terminal would fix this issue.
