kindly help.

I am using GNS3 v 0.6

Oh Well!

I have also followed the same instructions above. I am running the latest version of GNS3 0.7. I am saving my configs in a new working directory. I have went through the preferences and disabled the clean working area check box. After I have saved everything and I close out of GNS3. I can go to that directory and I see the R1.CFG files and so on.
When I start the project back up, if I click on the router and show startup-config. It shows the correct directory for my config. Once I start the router, I am presented with the “Would you like to enter the initial configuration dialog?”

After I say no to this I can issue the show startup-config command on the console. And the startup config is the correct config. However the running config is not. The Copy Start Run commands don’t work, becuase NVRAM is invalid or not present.

Any thoughts?

Thanks for the immense help you provide for the users community.

I hope my post might help others , rather than otherwise.

Sincerely
Elango

Opend the GNS3 gui and in Edit > Preferences > Dynamips :

1) changed the value of UDP increment to just 1 and
2) let the base UDP be the same 10,000.

Base UDP—— Generated UDP——–Increment Specfied————– Manual Incremented value( in *.net file)—————Result (saved topology)

10,000 — 10,000 — 1 — Not able to open.
10,000 — 10,000 — 100 — Not able to open.
10,000 — 10,000 — 1000 — Not able to open.

Opened GNS3 gui and edited : Edit > IOS images and Hypervisors > IOS images > Unchecked the hypervisor manager
then selected the only available hypervisor ( 127.0.0.1:7200) and then clicked Close.

11,000 — 10,000 — 100 — Not able to open.

Below is the value I used to open the saved topology.

Base UDP—— Generated UDP——–Increment Specfied————– Manual Incremented value( in *.net file)—————Result (saved topology)
10,000 — 10,000 — 100 — 11,000 —– Able to open.
10,000 — 10,000 — 100 — 10,001 —– Able to open.
————————–
It seems that irrespective of what value we use for the Base UDP or UDP increments in the GNS3 menu ( Preferences or IOS images & Hypervisors ), we cannot open the saved toplogy.

Whereas if we edit and change the UDP value to distinct ones, (just below each Hypervisors found in the *.net file) , which is greater than the BASE UDP value used to save the topology, I am able to open the saved topology, provided if the destination folders, IOS images used etc are correct.

This hold true for the above scenario.

I hope to explore more in this regard and post it int the forums
