How to Manage IPv6 Deployments

Training Course Description

This course focusses on identification of the most critical IPv6 deployment issues and will provide some guidance for smooth transition from IPv4 to Ipv6. We will identify different problem areas, e.g. around dual stack host implementations, OS dependencies with migration strategies, incompatibilities with DNS / DHCP requests and addressing schemes as well as different supported feature sets at network nodes (gateways, routers and servers).
In order to understand all possibilities and procedures, we will start with a discussion of all IP header field elements, identify all parts that have been inherited from IPv4, clarify the terminology and explain all the new header elements, their purpose and intended usage.
The IP header structure will be completed with the detailed consideration of the new concept of Extension Headers in IPv6 and the purpose and usage of each of the options.
We will then thoroughly discuss the address structure of IPv6 with the formats of Unicast, Multicast and Anycast addresses and what the options are to obtain a valid IP address.
The course will then explain, how ICMPv6 is structured and how it used to replace and incorporate all other support protocols known from IPv4. This will include detailed discussion of address generation options, including DHCP, Stateless Autoconfiguration, Neighbor Discovery and Duplicate Address Detection, critical issues for the deployment of IPv6.
Routing in IPv6 will be the next section, which identifies the protocol options within a domain and between domains and discussed the related protocols, such as RIPnG and OSPF.
With the basic IPv6 features and structures in mind, we will evaluate the potential and real obstacles in deploying a mixed IPv4 and IPv6 environment, discuss the missing backward compatibility and several enhancements to overcome address problems and concerns, as well as issues with mixed DNS and DHCP accesses.
A selected number of documented use cases will indicate fault situations due to improper and incompatible implementations in both hosts and network, e.g. dual stack behaviour, sequence of initialisations and fallback, support for various tunneling methods, multihoming issues etc.
We will familiarize the student with some commands to check and verify reachability, TCP and DNS connections.
We will then investigate various operational issues, starting with security in IPv6, usage in VPN networks with IPSec mechanisms for authentication and ciphering.
This will be followed by a study of Mobile IP with the basic operation and review of ICMP protocol enhancements for this case.

Some of your questions that will be answered

How does the IPv6 protocol header differ from IPv4?
Which elements are still used in IPv6 and what is the reason for changes in terminology?
What are Extension Headers, which information do they convey and how and when are these extensions being used in IPv6?
What is the structure of an IPv6 address and which parts are being used for public routing and how?
What are the changes in the support protocols such as ICMP and what happened to ARP in an IPv6 environment?
What is a Link-Local Address and how is that address obtained / generated?
What is the process and the purpose of Stateless Autoconfiguration and how does a terminal / application obtain an IP address in IPv6? How about DHCPv6, when and where must that be used? Is there a dependency with host operating systems?
How do routing protocols such as RIP and OSPF operate and where are they used?
How can Interworking with IPv4 and the migration from IPv4 be accomplished? What is the difference in DNS requests and records, where are the incompatibilities?
What is the difference of the various tunneling mechanisms, such as Teredo, 6to4 and others and where are they used?
What are the potential problem areas during IPv6 deployment related to implementation and compatibility issues between hosts and network nodes, e.g. in dual stack or tunneling environments.
Which are the security mechanisms provided with IPv6 and how is IPSec used for authentication and ciphering?
What is Mobile IPv6, how does it operate and where is it used?

Who should attend this class?

Test engineers who need to understand IPv6-features and their implications in detail.
Designers of IPv6 network domains who require a deep inside view of the various enhancements.
Anyone who need to understand the IPv6 terminology, features, addressing and routing mechanisms and the applicability in future networks.

Pre-Requisites

The student must possess a sound understanding of network architecture and packet routing in general and today's TCP/IP version in particular. There is no particular knowledge required regarding IPv6.
We do recommend our webinar or web based training courses on IPv6 as preparation for the course in order to improve efficiency and comprehension.

Training Course Target

The student is enabled to develop, test and integrate IPv6-equipment and protocols and to operate related networks.
