How to Configure IPv6 routing using Link Local IPv6 address

In this video, the presenter demonstrates how to configure IPv6 routing using link-local addresses. The process involves three main steps: assigning IPv6 addresses to both routers, discussing link-local addresses, and configuring IPv6 routing with these addresses. The presenter starts by configuring a fresh router and assigning an IPv6 address (2001:db8:1111:1::2/64) to a connected PC, confirming connectivity through a ping test. Next, they explain link-local addresses, which are automatically assigned by network interfaces when IPv6 is enabled, and provide an example of a link-local address (fe80::). To enable routing, the presenter uses the command "ipv6 unicast-routing" on both routers and discusses the importance of link-local addresses for routing packets without needing public IP addresses. They troubleshoot a ping issue caused by an inactive interface, demonstrating how to activate it using the "ipv6 enable" command. The video concludes with a summary of the configuration process.
