in: Uncategorized. Tagged: GNS3. 8 Comments PROBLEM Unable to to open saved topology in GNS3. SOLUTION Change ‘Base UPD' from 10000 UDP to 10001 UDP. To change it, go to “Edit” and click “Preferences …” or just use the shortcut key which is the combination of Ctrl+Shift+P. In Preferences, go to Dynamips, and look for Base UDP setting. Default Setting for Base UDP is 10000 UDP. Change Base UDP value from 10000 UDP to 10001 UDP and click OK.

The workaround is to open the topology file for editing and make the following change also udp = 10001 Reply Milan on September 17, 2013 at 11:53 am said: I did it , but its not working… Plz help to resolve it.

When I try to open it, I get this error that says: 206-unable to create UDP NIO How do I open my saved file so that I can continue working on unable to it? Quote tiersten was here. Join Date Apr 2008 Posts 4,504 07-27-201002:47 PM #2 2 reasons. Something else is using that UDP port which Dynamips wants to use or the net file is incorrect and one router is listening on one port whilst the other router wants to connect to a different port. Most probably the first reason anyway so go unable to create look at the Dynamips log to work out what is going on. Google for this next time as I just tried it and all the results point this out.
