We know that the devices on a network require a unique identification number called IP address. We have been using the IPv4 addressing scheme for a long time. But the addresses provided by the IPv4 addressing scheme are not sufficient as the demand of the Internet is increasing day-by-day. Hence, we require an addressing scheme that can provide more IP addresses along with the security features. Internet Protocol version 6 (IPv6) comes as a solution for this.
The IPv6 addressing scheme is an upgraded version of the IPv4 addressing scheme. It provides more IP addresses in comparison to the IPv4 addressing scheme. In the post “IPv6 Address Types and Features“, we have discussed a lot about the IPv6 addressing scheme. Please read it if you missed that one. In this post, we will discuss how to configure IPv6 on Cisco Routers.
