In this tutorial, i will demonstrate configuration of IPv6 addressing in both Windows XP machine and Cisco Router (GNS3).One of most flexible migration approach to IPv6 will be  “Dual-stack” approach which means that network devices will have both IPv4 and IPv6 addresses simultaneosly. Both TCP/IPv4 and TCP/IPv6 protocol stacks will work together seamlessly for quite some time.

IPv6 is also called IPng “IP Next Generation”. IPv6 offers exciting new features and addresses needs of today’s robust networking paradigm .

Following are few of many benefits of IPv6 :

  • Larger Address Space:IPv6 features a larger address space than that of IPv4: addresses in IPv6 are 128 bits long versus 32 bits in IPv4
  • Address Scopes :IPv6 introduces the concept of address scopes. An address scope defines the “region” or “span” where an address can be defined as a unique identifier of an interface.
  • Stateless address auto-configuration:IPv6 hosts can configure themselves automatically when connected to a routed IPv6 network using ICMPv6 router discovery messages.
  • Multicast / Multimedia :IPv6 offers built-in features for multicast groups, management and new ” anycast ” groups.
  • Mandatory network layer security :Internet Protocol Secutiry (IPSEC) ,the protocol for IP encryption and authentication, forms an integral part of the base protocol suite in IPv6.

    Please guide me if its possible for me to connect to internet using IPv6?

  2. admin says:

    Yes, its possible to coonect to IPv6 internet using tunneling.You can do this both on your PC (windows , Linux, MacOSx) and your Gateway (router). All you need to do is setup an IPv4 tunnel and pass IPv6 inside tunnel to your IPv6 tunnel broker.

    Hope this helps!Thanks!

    This is great. I have a question. If you didn’t manually configure the IPv6 address on the XP, wouldn’t it still autoconfigure after receiving Router Advertisement? In my lab, XP wasn’t autoconfiguring with an address other than link-local. But XP sets default gateway address, assuming it is receiving RA.

    I have a similar setup for Ipv6. I can snmp to the router’s IPv4 address, but to its IPv6 address is always unresponsive (Though I also can ping it). Any additional configure on the router to make its IPv6 address responds to the SNMP?

    hi, i beginner to gns3. i have try your tutorial on (GNS3: How to configure and setup IPv6 connectivity between Windows XP and Cisco Router) but i cannot make it at the part testing connection(ping) from the router to the PC(CO), no successful ping… can u tell me why this happen. are there need other setting to do it?
    hope you can help me. my email is

  6. admin says:

    @cheneww,there are lot of config examples on for details about configuring SNMP with IPv6.

    @arelee,Are you pinging right addresses ?Do you have Connectivity b/w Router and PC…first make sure your IPv4 connectivity is good,then try IPv6.

    I was able to successfully configure my PC for IPv6.Great work!

    Hi Great Work,

    But i want to know how can i connect my local pc to gns router, Plzzzz tell me .

    Hello Tariq, excellent blog and lots of help for us. I have a question about this lab though. When you were configuring the PC, you didnt specify the mask (for IPv6 global address) but for the router you specified /32. My question is does that matter, if i were to configure that in real world? Is IPv6 or can it determine the mask itself ?
