Configuring IPv6 with Cisco IOS

This chapter will explain the commands required to configure IPv6 addresses and associated parameters on the Cisco IOS, and should enable you to effectively configure IPv6 on either your own network or a customer s network. This chapter is geared toward those who want to learn the exact command syntax necessary to fully configure the Cisco router to support IPv6.
The second half of the chapter is dedicated to verifying the router configuration. We will cover the commands that are necessary to quickly view key information about the IPv6 configuration. Each command will be discussed in detail to ensure that you have all the tools necessary to configure and verify IPv6 on the IOS-based Cisco router.
The first step in configuring IPv6 on your router is making sure that the correct version of IOS is installed on the router. IPv6 was first introduced in IOS version 12.2(1)T Technology release, so that is the earliest version that can be used. The Cisco IOS version can be checked using the show version command, a sample output of which is seen below. For a thorough explanation of IOS version numbering, please visit Cisco s Web site.
