Description

The growth of the Internet and the adoption of networking over the past 20 years are pushing the IP version 4 (IPv4) to the limits of its addressing capacity and its ability for continued growth. To sustain the evolution of the Internet and the ability to scale networks for future demands requires a limitless supply of IP addresses and improved mobility. In response, the Internet Engineering Task Force (IETF) developed a next-generation protocol, IP version 6 (IPv6). IPv6 satisfies the increasingly complex requirements of hierarchical addressing that IPv4 does not satisfy. With a 128-bit address length, the IPv6 address space is significantly larger and more diverse, and thus is more complicated to manage. This course describes IPv6 main features, addresses, and basic configuration.
The header format for each IP packet carries crucial information for the routing and processing of each packet payload. Header construction plays an important role in the efficiency and extensibility of the network. ICMP plays an important role in troubleshooting networks, facilitating simple tools such as ping or determining that a packet could not reach its destination. This lesson describes both IPv6 and ICMPv6.
Any device that attaches to a network goes through numerous processes to identify itself and to obtain services from the network. This premise is true in either an IPv4 or IPv6 network. However, people who design and manage IPv6 networks will discover that although the processes that are used in IPv6, have some similarities to those that are used in IPv4, they are different. Understanding these processes is fundamental to properly supporting an IPv6-enabled environment.
This course describes IPv6 neighbor discovery, which is the process in which neighbors discover each other and autoconfigure addresses. The course also explains how stateless autoconfiguration helps to automatically assign IPv6 addresses to devices in the network.
Routing protocols must support IPv6 to facilitate the successful transport and operations of IPv6-generated traffic. OSPF is a widely used IGP. Understanding the differences between OSPF version 2 (OSPFv2) and OSPF version 3 (OSPFv3) are required for the successful deployment and operation of an IPv6 network using OSPF for routing. This course completes by describing how to configure and verify static IPv6 routes and OSPFv3.
