Cisco Self-Study: Implementing IPv6 Networks (IPV6)

IPv6 Features

After the overview of the main problems related to the IPv4 protocol, you should see that IPv6 solves all these problems and provides new benefits. Here are the main improvements:

• The 128-bit address scheme, which provides plenty of IP addresses for the next decades.

• The larger address space provides globally unique addresses to billions of new devices such as PDAs, cellular devices, and 802.11 systems, that will be manufactured in the future.

• Multiple hierarchy levels help aggregate routes, which promotes efficient and scalable routing to the Internet.

• Multihoming with the preservation of strict route aggregation is possible.

• The autoconfiguration process allows nodes of the IPv6 network to configure their own IPv6 addresses.

• The transition ...
