Summary

In this chapter, you learned about the new IPv6 header format and the impact of IPv6 on User Datagram Protocol (UDP), Transport Control Protocol (TCP), and Maximum Transmission Unit (MTU). You also learned about IPv6's addressing architecture, with its different kinds of IPv6 addresses such as link-local, site-local, aggregatable global unicast, loopback, unspecified, IPv4-compatible, multicast assigned, solicited-node multicast, and anycast. This chapter also covered IPv6 over Ethernet, multicast mapping over Ethernet, and EUI-64 format.

You learned how to configure and operate Cisco routers with IPv6. You saw examples of how to enable IPv6 on a router and configure static IPv6 addresses on network interfaces such as aggregatable global unicast, site-local, and link-local. Then you configured IPv6 addresses using EUI-64 format and defined the MTU on the interface. Finally, you verified aggregatable global unicast, site-local, link-local, multicast assigned, and solicited-node multicast addresses enabled on the router's network interfaces.
