Here are the key steps to include IPv6 on an existing IPv4 MPLS VPN using 6PE and CsC:
1. Upgrade PE routers to support 6PE and CsC. This allows the PEs to tunnel IPv6 packets over the existing IPv4 MPLS infrastructure.
2. Configure loopback addresses for the PE routers and advertise these addresses over MP-iBGP to exchange IPv6 reachability information.
3. Configure IPv6 VPN address families and enable the send-label option to exchange VPNv6 routes and labels over MP-iBGP.
4. Configure IPv6 VPN routes on the PEs and redistribute these routes into the VPNv6 address family to advertise to other PEs.
This document discusses the transition from IPv4 to IPv6 over time. It describes several methods used for the transition, including: dual-stack which allows both IPv4 and IPv6 on devices; tunnels which allow IPv6 traffic to be carried over IPv4 networks; and network address translation protocols like NAT64 which allow translation between IPv4 and IPv6. The document outlines the progression of transition technologies from early experiments with tunnels in the 1990s to current approaches using address and port translation to share limited IPv4 addresses. Security challenges are also discussed, such as inability to inspect tunneled traffic and threats to stateful translation protocols.
This document provides an overview and agenda for a course on Introduction to IPv6 for Service Providers. The course covers IPv6 essentials such as addressing, operations, applications/services, routing protocols, and transition strategies. It discusses the rationale for adopting IPv6 including the depletion of IPv4 addresses and the need to support the growing number of internet-connected devices. The document outlines some of the key limitations of IPv4 like fragmentation and the issues with long-term reliance on Network Address Translation (NAT) to overcome the address space depletion.
A presentation that tries to set an IPv6 agenda for the SIP community. VoIP and IPv6 is a natural match. If we want unified communication to be truly global and unified - we need to build solutions on IPv6 and not Ipv4.
This document discusses Samba and IPv6 support in Windows Vista. It notes that while raw SMB file sharing works over IPv6 in Samba 3 and Samba 4 with some workarounds, Samba cannot currently function as an Active Directory domain controller for IPv6 clients like Vista. It recommends that further work is needed in Samba 4 to fully support IPv6, especially for Active Directory functions, to allow organizations migrating to Vista and IPv6 networks to use Samba.
2015 update: SIP and IPv6 issues - staying Happy in SIPOlle E Johansson
What's the state of SIP and IPv6?
- An update I gave at the Netnod spring Meeting 2015.
Nothing much is happening, despite the fact that we have proven real issues with dual stacks in SIP.
This document discusses IPv6 transition and the state of IPv6 adoption. It notes that while IPv4 address exhaustion is a real issue, users do not care and prefer NAT for security. Transition requires cooperation across users, ISPs, devices and content. Statistics show rapid growth of IPv6 adoption by major networks worldwide in the last two years. Full transition to IPv6 is needed to enable unlimited connectivity for cloud/mobile internet and the internet of things going forward.
This document discusses various techniques for transitioning from IPv4 to IPv6, including dual stacking, tunneling, and translation services. It provides examples of configuring dual stacking and manual IPv6 tunnels on Cisco routers to connect isolated IPv6 networks over an IPv4 infrastructure. Dual stacking allows hosts and devices to run both IPv4 and IPv6 simultaneously, while tunneling encapsulates IPv6 packets in IPv4 to enable connectivity across non-IPv6 networks. The document demonstrates establishing an IPv6 tunnel between two routers and routing IPv6 packets over the tunnel using RIPng.

Jumping Bean offers IPv6 training for businesses (http://www.jumpingbean.co.za/ipv6-training)
This document discusses IPv6 transition strategies for service providers. It begins by noting that the IANA pool of IPv4 addresses has been exhausted and regional registries will soon run out as well. While existing IPv4 networks will continue to function, many devices and applications only support IPv4, creating an "IPv4 long tail" that will be challenging to transition to IPv6. The document then evaluates options for service providers, including dual-stack, translators, and tunnels. It provides more detail on implementing a dual-stack infrastructure in the core network using protocols like IS-IS, OSPF, and BGP. 6PE and 6VPE are introduced as options to provide IPv6 connectivity over an IPv4 MPLS
A quick introduction to Kamailio - the leading Open Source SIP server (based on OpenSER and SER). Kamailio is quite different than Asterisk, FreeSwitch and many other VoIP platforms - why is that and how do you start getting your head around Kamailio?
instructor ppt_chapter8.2.2 - i_pv6 addressing with exercises of IPv6cyberjoex
The document discusses IPv6 addressing and the transition from IPv4 to IPv6. It covers the need for IPv6 due to the depletion of IPv4 addresses, the structure of IPv6 addresses which use 128-bit addressing and are written in hexadecimal, and methods for compressing IPv6 addresses. IPv6 addresses can be represented in different compressed formats by omitting leading zeros in each section or replacing consecutive sections of zeros with a double colon. The document also discusses types of IPv6 addresses and techniques for IPv4 and IPv6 coexistence like dual stack, tunneling, and translation.
IPv6 Transition Strategies discusses various strategies that service providers can take to transition from IPv4 to IPv6 as IPv4 addresses run out. The document outlines strategies such as doing nothing and extending the life of IPv4 through NAT, as well as transition techniques like deploying a dual-stack network with both IPv4 and IPv6, using 6rd for rapid deployment of IPv6 to customers, and employing address translation methods like Carrier Grade NAT, Dual-Stack Lite, NAT64, and 464XLAT. The best long term strategy is considered a fully dual-stack network, but near term options include dual-stack with SP NAT or IPv6 transition techniques that allow continued use of IPv4 where needed.
This document summarizes gogo6's IPv6 access and IPv4 coexistence solutions. It introduces gogo6's TSP tunneling technology which allows IPv6 connectivity over IPv4 networks using plug-and-play CPE devices. The solution scales gradually by adding more gateway servers as traffic increases and provides a way to transition networks to IPv6 without replacing entire infrastructures.
Network address translation (NAT) allows remapping of one IP address space to another. Types of NAT include static NAT, dynamic NAT, and port address translation (PAT). NAT provides benefits like IP address conservation, security, and flexibility. On Cisco routers, NAT operations follow an order of inside-to-outside and outside-to-inside translation. NAT can be deployed in scenarios involving MPLS VPNs, IP multicast, high availability, and application-level gateways. Configuration of NAT varies between Cisco routers and ASA firewalls.
The document discusses IPv6 and its advantages over IPv4. Some key points:
- IPv6 addresses are 128 bits, compared to 32 bits for IPv4, allowing for virtually unlimited unique addresses. IPv6 uses unicast, multicast, and anycast but not broadcast.
- IPv6 simplifies the header format and allows for extension headers to add new features. It also eliminates checksums and performs fragmentation only at the source.
- IPv6 was designed for autoconfiguration, allowing nodes to automatically obtain addresses and other information via protocols like SLAAC and DHCPv6.
The document discusses the transition from IPv4 to IPv6. It notes that IPv4 only provides 4 billion addresses, which is inadequate for today's internet-connected devices, and that IPv6 was developed to address this shortage by providing vastly more addresses. Specifically, IPv6 uses a 128-bit address scheme to allow up to 340 undecillion unique addresses. The document outlines some key advantages of IPv6, such as easier address management and autoconfiguration, as well as built-in security and support for an increasingly mobile internet.

The document compares features of IPv4 and IPv6 such as address syntax, header fields, and configuration methods.
Overview of IPv6 protocol along with various transition scenarios for the migration from IPv4 to IPv6
IPv6 is the current and future Internet Protocol standard. As anticipated, IPv4 addresses became exhausted around 2012.
The IP address scarcity is the main driver for IPv6 protocol adoption.
IPv6 defines a much larger address space that should be sufficient for the foreseeable future, even taking into account Internet of Things scenarios with zillions of small devices connected to the Internet.
IPv6 is, however, much more than simply an expansion of the address space. IPv6 defines a clean address architecture with globally aggregatable addresses thus reducing routing table sizes in Internet routers.
IPv6 extension headers provide a standard mechanism for stacking protocols such as IP, IPSec, routing headers and upper layer headers such as TCP.
ICMP (Internet Control Message Protocol) is already defined for IPv4. ICMP was totally revamped for IPv6 and as ICMPv6 provides common functions like IP address and prefix assignment.
Lack of business drivers for migrating to IPv6 is responsible for sluggish adoption of IPv6 in carrier and enterprise networks.
Numerous transition mechanisms were developed to ease the transition from IPv4 to IPv6. Many of these mechanisms are complex and difficult to administer.
The transition mechanisms can be coarsely classified into dual-stack, tunneling and translation mechanisms.
This chapter discusses IPv6, the next-generation Internet protocol. IPv6 was created to address the impending exhaustion of IPv4 addresses as the number of internet-connected devices grows rapidly. IPv6 uses 128-bit addresses compared to 32-bit addresses in IPv4. It supports various address types including unicast, multicast, and anycast. IPv6 also introduces mechanisms for address autoconfiguration and supports tunneling techniques for transitioning to IPv6, such as 6to4 tunnels.

The document discusses IPv6, the next generation internet protocol. It introduces IPv6, describing its benefits over IPv4 including vastly larger address space. It then covers key aspects of IPv6 such as address types, auto-configuration, routing protocols, and technology scope. IPv6 aims to meet growing internet demands through expanded addressing and more efficient headers.
The implementation of embedded IPv6 applications in an IPv4 world require one of several strategies of converting or tunneling IPv6 traffic through the IPv4 internet.
The document outlines an agenda for a 3HOWs event discussing IPv6 and MPLS technology. The morning sessions will cover how to deal with IPv6, including why it is important now due to limited IPv4 addresses, IPv6 addressing details, and how to connect to IPv6. The afternoon will discuss how to connect with MPLS technology, the benefits it provides for interconnecting offices, and actual customer case studies. Questions from attendees will conclude the event.
This document provides information about IPv6 addressing and describes a lab exercise to help identify different types of IPv6 addresses. The lab has three parts: 1) Identify types of IPv6 addresses based on address prefixes, 2) Examine a host's IPv6 network settings to find its link-local address, 3) Practice abbreviating IPv6 addresses using defined rules. Key points covered include the structure of IPv6 addresses, common address types like link-local and global unicast, and how to compress addresses using techniques like omitting leading zeros and replacing runs of zeros with "::".
The document discusses IPv6 over MPLS on Cisco routers, including:
- 6PE allows IPv6 connectivity over an IPv4/MPLS backbone by using MPLS labels between PE routers to tunnel IPv6 packets. Configuration on Cisco routers is straightforward, requiring IPv6 BGP neighbor configuration and the "neighbor send-label" command.
- 6VPE extends the concept of VPNs to IPv6 using scoped addressing architecture. It allows dual-stacked VRFs for consistent IPv4 and IPv6 VPN services. Configuration requires defining VRFs and associating interfaces using "vrf forwarding".
Internet Protocol version 6 (IPv6) is the latest version of the
Internet Protocol (IP), the communications protocol that
provides an identification and location system for computers
on networks and routes traffic across the Internet.
IPv4 & IPv6 are not designed to be interoperable, complicating
the transition to IPv6. However, several IPv6 transition
mechanisms have been devised to permit communication
between IPv4 and IPv6 hosts.
The document provides an overview of IPv6 addressing and configuration. It describes:
- Three key features of IPv6 addressing - unicast, multicast, and anycast addresses. IPv6 uses link-local and global unicast addresses.
- Methods for configuring IPv6 addresses, including static configuration of link-local and global unicast addresses, as well as dynamic configuration using stateless address autoconfiguration (SLAAC) and stateful DHCPv6.
- Router advertisement and router solicitation messages used in the dynamic configuration processes, and how these messages can specify use of SLAAC, SLAAC with stateful DHCP, or stateful DHCP alone.

3. IPv6 in z/VSE
IPv6 News is everywhere
With z/VSE 4.2.2 IBM announced
IPv6/VSE
Full IPv4 and IPv6 TCP/IP solution
Stacks and applications
IPv6/VSE will take z/VSE and you into
the future!
3
4. IPv4 Review
IP addresses are 32-bits
4,294,967,296 different IP addresses
Many are reserved
288 Million in fact
Dotted decimal notation
192.168.1.1
4
7. IPv4 Issues
Asia already out of IPv4 addresses
Europe will run out of IPv4 addresses very soon
Are you ready?
How will this affect your business operations?
How will you communicate with your customers
when they are using IPv6?
7
8. IPv4 Issues
NAT (Network Address Translation)
Map multiple internal addresses to
single external address
Most routers (cable/DSL) do this
Time consuming
Complicated
8
9. IPv4 Issues
Variable length IP Header Options
are time-consuming
IP Header checksum is redundant
and time-consuming
Fragmentation of IPv4 packets is
inefficient
Classification of IPv4 packets still exists
9
10. What is the Answer?
The solution is IPv6
Wait! What happened to IPv5?
Internet Stream Protocol (ST/ST-II)
experimental protocol used IP version
number 5.
ST/ST-II was never known as IPv5
10
11. Why is IPv6 Better?
Designers tried to avoid IPv4's mistakes
128 bit IP addresses (16 bytes)
Large Packet support
Fixed headers
No fragmentation
No checksums
11
12. Why is IPv6 better?
Easily extendable
Simplier routing
True multicasting
Automatic configuration
Full mobile device support
12
13. IPv6 Basics
IPv6 addresses are big. Very Big.
IPv6 addresses are 16 bytes in length
(vs. 4 bytes for IPv4 addresses).
That’s 2^128 IPv6 addresses
(about 3.4 x 10^38) unique addresses.
Or about 5 x 10^28 IPv6 addresses for
each person in the world.
13
14. IPv6 Basics
IPv6 addresses are usually written as
groups of four hexadecimal digits (base
16) with each group representing 2 bytes
of the 16-byte address.
2001:0db8:85a3:08d3:1219:8a2e:0370:7344
Now that’s a mouthful!
14
15. IPv6 Basics
To help, leading zeroes can be omitted
fd00:0806:0001:0000:0000:0000:0000:0001
would become
fd00:806:1:0:0:0:0:1
and consecutive all-zero groups can be
replaced by two colons
Fd00:806:1::1
15
16. IPv6 Basics
An IPv6 address is assigned to a
network interface
Each interface (network adapter) can
have multiple IPv6 addresses
All network interfaces have at least two
the assigned IPv6 address
the Link Local IPv6 address
16
19. IPv6 Basics
Plug-n-Play IP addressing
Hosts solicit
Routers Advertise
ICMPv6 Neighbor Discovery eliminates
ARP processing (and its overhead!)
19
20. Migrating from IPv4 to IPv6
IPv6 is NOT backward compatible with IPv4
IPv4 and IPv6 can coexist
Dual stack approach is best
IPv4 continues unchanged
IPv6 introduced
Running together on the same system
Windows and Linux provide excellent
dual stack support
20
21. Can my ISP do this for me?
Carrier-Grade NAT (CGN)
Large-Scale NAT (LSN)
All companies and users provided local
IP addresses
ISP uses a single (or a few) public IP
addresses
Shifts NAT from users to the ISP
21
22. CGN/LSN Issues
It breaks the end-to-end principle, resulting in
security issues (think SSL)
It has significant security, scalability, and
reliability problems due to its stateful design
It makes record keeping for law-enforcement
operations more difficult
It makes it impossible to host services on well-
known ports
22
23. CGN/LSN Issues
Poorly suited to handling business
customers
Best suited to residential internet users
At best, a temporary solution
23
24. OK, What about z/VSE?
Bet you are hearing about IPv6 now
Perhaps your ISP has made it available
to you
Other businesses or customers have
requested it
The US Government DoD requires it
US Unified Capabilities Approved
Products List (UC APL) requires it
24
25. Introducing IPv6/VSE
IBM licensed IPv6/VSE as their TCP/IP
product solution for the future
IBM's IPv6/VSE announcement (210-
066) was made on April 6, 2010
The availability of IBM's IPv6/VSE allows
z/VSE users to participate in an IPv6
network and bring the benefits of IPv6
functionality to z/VSE users
25
26. Introducing IPv6/VSE
While the product is named IPv6/VSE, it
supports both IPv4 and IPv6 communications
IPv6/VSE provides a full-function IPv4 stack
and applications as well as a full-function
IPv6 stack and applications
Both TCP/IP stacks (IPv4 and IPv6) can be
run together, individually or even standalone.
