Anyone tunnel their GNS3 labs together? I would think with a lot of little labs connected together you could create a big GNS3 internet.

altafk, you hear about freepeerx.org? You can run BGP over GRE tunnels with this. Of course, you can do that with anybody, but this guy is sort of aggregating it.

brendan this is the first time i am learning about this tunnel over internet thing.
I know about GRE tunnel but connecting our networks over internet is something i am being introduced by you.
i must thank u for making us aware of such thing.
I would like to learn more about it.

Thanks once again

Hey altafk

If you have Linux on the internet, you can start the tunnel like this.

/sbin/ip tunnel add tun10 mode gre remote 72.205.54.70 local ttl 255
/sbin/ip addr add dev tun10
/sbin/ip link set tun10 up
/sbin/ip route add 10.10.11.0/30 dev tun10

That last route goes to my lab. You can use Cisco, too. I got IPsec and GRE tunnels to other Cisco and Linux devices.

I bet you can do this in Windows if you have a PPTP client. Send me a message if you want to email.

Hey brendan,

I was thinking of creating our own lab in gns3 and directly creating a tunnel using GRE in our lab itself.

We just need to pass GRE in our firewalls and we can exchange routes using any routing protocol.

Correct me if i am wrong !

yep, I think people are doing this already. They connect their GNS3 labs to the iinternet in whatever way possible.

Email me if you want to try out!

Great idea. We'd all benefit from a distributed GNS3 network.

Currently, my computer can only run about 14x IOS instances before it becomes unusable... imagine what we've have we combined our labs!

Oh, and thanks Brendan - I've just signed up on FreePeerX!

Im finally setting up my ibm x3850 server for use as a GNS 3 test machine (4 dual core processors and 64gb ram), would be very interested in joining up servers...
