foreign friends, I a new learner of ipv6 in china.nowadays ,our teacher and us want to construct a simulated ipv6 to ipv4 network using tools like packet tracer,GNS3,boson,ns2,but my knoledge is not that enough and we cannot find many doc with chinese search engin www.baidu.com ,and we cannnot visit website like youtobe,so,can you friends give us some links about that and tell me the softwares above can be used for the test or not .I searched may be packet tracer is not available for NAT-pt and tunnels

I don't think Packet Tracer supports IPv6.

Sure PT v5.3.3 supports IPv6. In Global config mode the following commands are available, including v4v6 and v6v4 nat:

To the OP - Is your instructor giving you any information in class?
Here's a Cisco configuration guide for IPv6:
http://www.cisco.com/en/US/docs/ios/ipv ... _book.html

However, I think non-English documentation will be difficult to find.

Are you a Cisco Networking Academy student?

"ipv6 unicast-routing"
But you're working on Packet Tracer. Most IPv6 stuff won't work.

“protocol not running” is a very big hint, so as Reggle says, “ipv6 unicast-routing” should have been your first thing to try. The purpose of error messages is usually to tell you something, albeit sometimes they are a little cryptic.

But there are a couple of basic things you also need to consider –

(1) A simulated device in Packet Tracer, like a real device, cannot guess what you want to do – so you need to know all the commands before you try to configure anything.

(2) Like all good software, Packet Tracer has extensive Help resources – it pays to use them – From Help > Contents > Configure Devices > Router IOS you find the global config commands that I posted back in the 3rd reply to this thread back in April!

In Interface Mode available IPv6 commands are –
Code:
ipv6
  address
    autoconfig
    ipv6-prefix/prefix length
    anycast
    eui-64
    ipv6-address
    linklocal
    prefix-name ipv6-prefix/prefix-length
  enable
  rip WORD
    default-information originate
    enable
  eigrp <1-65535>
    summary-address eigrp <1-65535> X:X:X:X::X/<0-128> [ <1-255> ]
    hello-interval eigrp <1-65535> <1-65535>
  ospf
    <1-65535> area area-id [instance instance-id]
    cost <1-65535>
    dead-interval <1-65535>
    hello-interval <1-65535>
    priority <0-255>
  dhcp
    client pd WORD
    server WORD
  nat
    prefix X:X:X:X::X/<0-128> [v4-mapped] [WORD]
  mtu <1280-1500>


Plenty to get you started in IPv6 I would think.

Aubrey

Hi friends,

I'm doing my thesis about interconnection IPV4 and IPV6. I using 5.3.3 packet tracer.
I would like to connect 2 building with tunneling methods but up till now i couldn't to send the packet data from building 1 to building 2. There's cloud between the router 1 and router 2. Can somebody help me to solve this matter? What should I do? Thanks

Hi Folks

i am trying to ping two 2811 routers(ping R1 from R2) using ipv6 in Packet Tracer 5.3.3.Please be informed that it is a simple ping command and no routing protocol is involved. The whole syntax for two routers is as follows :

R1>enable
R1#configure terminal
R1(config)#no ip domain lookup
R1(config)#ipv6 unicast-routing
R1(config)#interface serial 0
R1(config)#ipv6 address 3ffe:b00:ffff:1::1/64 eui-64
R1(config)#ipv6 enable
R1(config)#no shutdown


R2>enable
R2#configure terminal
R2(config)#no ip domain lookup
R2(config)#ipv6 unicast-routing
R2(config)#interface serial 0
R2(config)#ipv6 address 3ffe:b00:ffff:1::2/64 eui-64
R2(config)#ipv6 enable
R2(config)#no shutdown

R2#ping ipv6 3ffe:b00:ffff:1::1/64

it gives me following error message
"Translating "3ffe:b00:ffff:1::1/64"
% Unrecognized host or address or protocol not running"

Can anybody please let me know what is the issue with this syntax or where i am getting it wrong ?
Thanks ..........appreciate your support in solving this

Your specific question has already been answered in previous posts in this thread.

Hint (again) "protocol not running" usually means that the protocol (the Network Layer protocol) that you are trying to test is not running - which in this case is IPv6 - so you have to turn it on. To see how to do that read the above posts.

Aubrey

Drop the prefix from the ping command.

To kbtahir - in case you haven't got it. I'm pretty new to this myself but I think the posts said that you needed to enable IPv6.

IP(v4) runs by default, but you have to explicitly enable IPv6 globally on each router. Thus;

Router(config)#ipv6 unicast-routing

You should then find it recognises the format of your IPv6 address - which it currently is not doing.

Guys, I'm having a bit of trouble with Packet Tracer and IPv6. One router on the edge of my network doesn't like IPv6 and I don't know why.
It can ping the link-local add on the interface at the other end of the serial link and that can ping this router's interface's link-local address. However neither can ping the global addresses.
Have enabled ipv6 unicast.
Have enabled interface.
Have configured IPv6 addresses
Have also enabled RIP [word] on router and interfaces. Not that that should matter?

One other thing is that not one of my routers can ping the IPv6 loopback address in Packet Tracer.... which does have SOME issues with IPv6 from my limited experience.

Well I solved the immediate problem by turning the routers off and on again. No joke. However the problem returned and I think I have a routing loop. It appears that Split-horizon does not function in IPv6 in Packet Tracer. I have tried manually configuring, but it doesn't work and the option:

(conf-if)#ipv6 split-horizon

doesn't exist.

Ho hum..
