  1. i have installed GNS 2.0.3 version on my pc and m getting different options on setup wizard.
    1. Run modern IOS(IOSv or IOU), ASA and appliances from non Cisco manufacturers.
    2. Run only legacy IOS on my computer.
    3. Run everything on a remote server (Advanced usage).
    could u pls tell me, which option i should go for?

  2. Hi, thx for the video.
    But I have a problem after installing Vios-2 which is when I run the MSW then I issue for example #show int g0/0 then in the output it say unknown Media Type which in the result of that SW can't do the negotiation for speed and duplex and reads all the interfaces as shared type (Like a hub interface) in the output of # show spanning-tree .
    I googled a lot about it but I couldn't find a solution to that, I also used different versions of GNS3 like 1.5.3 and 2 but the same issue.
    if you could guide me through that it would be great.
