Are there any good Network Simulators/Trainers out there that support IPv6? I want play around with some IPv6 setup.

GNS3
http://www.gns3.net/

  This is another network simulator, mainly for academic research.

NS-2
http://www.isi.edu/nsnam/ns/

  And you can always setup some virtual machines with DNSs, hosts and routers with open-source software.

  Also to add:

  http://warriors.eecs.umich.edu/viz_tools/nam.html (referenced from
  ISI.edu/nsnam above), and the Java version, JAVIS

  Also worth looking at:

  http://www.csse.uwa.edu.au/cnet/ (more for pure network simulation, not
  tied to any particular protocol).

  And of course, as suggested above, just using a virtual network using
  something like VirtualBox/KVM and some Linux/BSD boxes, and throw in
  maybe Dynamips / Dynagen / GNS3 (http://www.gns3.net/) if you want to
  simulate some IOS.

  Finally something like Quagga/BIRD for the routing protocol part.

im using KVM with briged interfaces and JunOS Olive or vyatta

I like Cloonix [1]. It still has some rough edges, but is quite easy to
hack into. Used it for testing IPv6 configurations =)

I am currently researching virtual simulation environments for the
Networking courses that I teach. I am now interested in user-mode
linux emulators as they provide more real environments.

The one that I am liking the most right now is this one:

So far GNS3 has won out so far. It seems to work on my Mac fairly well. trying it out now.

James:

I've been resisting GNS3 for the longest time, because I like real equipment and to get my hands a little dirty.
But for the purpose of simulation, GNS3 helped me identify a BGP issue last week. If it weren't for GNS3,
I would not have been able to figure it out.

I will be using GNS3 in the future now for as much I can. Remember it is more router oriented than switch.

So you can't do any fancy L3 switching......

what are you trying to simulate?
  o control plane?
  o traffic?
  o interfaces and layers 1-3?
  o ...

makes a big difference

products which I've recently evaluated for use in network simulation
with relevance to ipv6.

shunra - latency simulator nework property simulator.
ixia - traffic generation, protocol simulation, control plane traffic
spirent - see above.

all three have v6 support.

If you have access to IOS images, look at GNS3

You can do some switching by stuffing a virtual NM-16ESW into your
faketastic 3660 in Dynamips. Then there are the built-in frame-relay and
ethernet switches you could dump into the mix as well.

If you looking for network simulator for Cisco equipment it's been my experience that Boson (www.boson.com) has best network simulator for Cisco equipment. It behaves and process information the way real Cisco equipment does. I've tried GS3, it great for routing situations but lacks in simulating switches.

Anything for Junipers ?
