IPV6 and RouterOs CHR, error

RouterOS General
1

Hi, i´m was trying to make a laboratory in GNS3 about IPV6 tunnels, when i get activated IPV6 packet, the chr router in GNS3 become inestable, Ej. try to exec ip address print causes the CLI hangout, the same behavior in winbox, the router reboot.

What OS are you using? I had the same experience with Windows7. On Linux it’s ok for me.

I wouldn’t say it’s exclusive to IPv6. I’ve run a lot of CHR in GNS3 primarily in 2.0 now and everyonce in a while I have to power cycle one, some or all of a MikroTik lab over and over again until they stay responsive. I don’t know why but they do it on both Windows w/GNS3 VM and Fedora Linux.

I just ran into this issue when trying to use IPv6 on Windows 10 with GNS3. As soon as I enabled the IPv6 package, the CLI would hang.

Here is what I did to resolve it:

Increase the memory for the VM from 128MB to 256MB
Select “legacy networking mode” in GNS3 and use the Legacy paravirtualized NIC (virtio)

Hope this helps someone :slight_smile:

Thanks I’ll try the paravirtualized NIC. I had tried different RAM sizes as well in the past.

Thanks a lot.
I tried your suggestions and work fine for me, great solution and very simple.
