IPv6 Fundamentals: A Straightforward Approach to Understanding IPv6 (Fundamentals Series)
Format: PDF / Kindle (mobi) / ePub
To support future business continuity, growth, and innovation, organizations must transition to IPv6, the next generation protocol for defining how computers communicate over networks. "IPv6 Fundamentals" provides a thorough yet easy-to-understand introduction to the new knowledge and skills network professionals and students need to deploy and manage IPv6 networks. Leading networking instructor Rick Graziani explains all the basics simply and clearly, one step at a time, providing all the details you'll need to succeed. Building on this introductory coverage, he then introduces more powerful techniques that involve multiple protocols and processes and provides hands-on resources you can rely on for years to come. You'll begin by learning why IPv6 is necessary, how it was created, and how it works. Next, Graziani thoroughly introduces IPv6 addressing, configuration options, and routing protocols, including RIPng, EIGRP for IPv6, and OSPFv3. You'll learn how to integrate IPv6 with IPv4, enabling both protocols to coexist smoothly as you move towards full reliance on IPv6. Throughout, Graziani presents all the IOS command syntax you'll need, offering specific examples, diagrams, and Cisco-focused IPv6 configuration tips. You'll also find links to Cisco white papers and official IPv6 RFCs that support an even deeper understanding. Rick Graziani teaches computer science and computer networking courses at Cabrillo College. He has worked and taught in the computer networking and IT field for nearly 30 years, and currently consults for Cisco and other leading clients. Graziani's recent Cisco Networking Academy Conference presentation on IPv6 Fundamentals and Routing drew a standing audience and the largest virtual audience for any session at the event. He previously worked for companies including Santa Cruz Operation, Tandem Computers, and Lockheed. - Understand how IPv6 overcomes IPv4's key limitations- Compare IPv6 with IPv4 to see what has changed and what hasn't- Represent IPv6 addresses, including subnet addresses- Enable IPv6 on router interfaces using static, dynamic, EUI-64, unnumbered, SLAAC, and DHCPv6 approaches- Improve network operations with ICMPv6 and Neighbor Discovery Protocol- Configure IPv6 addressing and Access Control Lists using a common topology- Work with IPv6 routing tables and configure IPv6 static routes- Compare, configure, and verify each IPv6 IGP routing protocol- Implement stateful and stateless DHCPv6 services- Integrate IPv6 with other upper-level protocols, including DNS, TCP, and UDP- Use dual-stack techniques to run IPv4 and IPv6 on the same device- Establish coexistence between IPv4 and IPv6 through manual, 6to4, or ISATAP tunneling- Promote a smooth transition with NAT64 (Network Address Translation IPv6 to IPv4)- This book is part of the Cisco Press Fundamentals Series. Books in this series introduce networking professionals to new networking technologies, covering network topologies, sample deployment concepts, protocols, and management techniques.
Infrastructure. Tunnels or overlay tunnels were discussed. This is another way that IPv4 and IPv6 devices can coexist. Tunneling allows IPv6 devices to communicate over an IPv4-only network by encapsulating the IPv6 packets inside an IPv4 packet. Tunneling should be considered a temporary solution until native IPv6 can be employed. The first type of tunnel examined was a manual tunnel. Manual tunnels are point-to-point tunnels where the IPv4 source and destination addresses are statically.
Advertise this prefix. Dynamic NAT-PT Static NAT-PT is useful when there are a limited number of IPv6-to-IPv4 mappings and when the addresses are stable—unchanging. With dynamic NAT-PT, IPv4 addresses are allocated from an address pool similar to what is done with dynamic IPv4 NAT. With dynamic NAT-PT, when the NAT-PT router receives a packet with a destination IPv6 address using the assigned /96 NAT prefix, the same process occurs as did with static NAT-PT. However, instead of translating the.
Removed in the IPv6 header. The Checksum field is used to verify the integrity of the UDP header and data. Note The Checksum field in Transmission Control Protocol (TCP) is mandatory for both IPv4 and IPv6. TCP and UDP run on top of IPv6 without any structural modifications to these protocols. TCP, UDP, and other upper-layer protocols are examined in Chapter 9, “DHCPv6 (Dynamic Host Configuration Protocol version 6).” Fragmentation When the Fragment extension header was discussed earlier, it.
This chapter also explores IPv6 access control lists, with configuration examples using the common topology. • Chapter 7, “Introduction to Routing IPv6”: This chapter examines the IPv6 routing table and changes in the configurations pertaining to IPv6. It also discusses the configuration of IPv6 static routes that are similar to static routes for IPv4. CEF for IPv6 is also covered. • Chapter 8, “IPv6 IGP Routing Protocols”: This chapter discusses three routing protocols: RIPng, EIGRP for IPv6,.
Updated—which displays the last time the route was updated in hours:minutes:seconds, day, month, and year. Note Most of these options are beyond the scope of this book and will not be discussed.

Let’s begin by examining the routing tables of Router R1. Yes, routing tables—plural. In Example 7-1, the show ip route command is used to display the.
