Saving the configuration in GNS3

Hello,
I'm using GNS3 to interconnect two routers R0 and R1. I have configured them correctly and I'm able to test the ping; everything is working well, but I have a problem concerning the saving of the configurations for R0 and R1. I used the command write and also export /all, but once I exit GNS3, I only find the topology backup (interconnected R0 and R1) and I can't find the configuration I made.

Thank you in advance

    Hello everyone. I've encountered this problem several times in GNS3, and I think I have found a solution for saving router configurations. I say "I think" because it works for me and everyone I've assisted (XP - Vista - Seven).
    So, first of all, make sure you have configured GNS3 properly (Edit > Preferences). Then start a new project (File > New topology). When the " New project " window appears, simply check, and only check the first box "Save NVRAMs and other virtual disks", then give a name to your project; the default path will be constructed automatically. Then validate!!
    There you go, it's done. This is how I always recover my router settings after closing GNS3. I recommend first testing with a project containing only one router before moving on to larger labs.
    I hope I helped you. If you want more details on the proper configuration of GNS3, feel free to reach out...

      Hello, I am currently working on some projects in GNS3, would you happen to have any explanations on VPN or Frame Relay?

      Thank you in advance

      It's all vague.
      Make a summary with configurations and explain what doesn't work, and we'll try to explain to you why it doesn't work.

    Hello

    you can type the command copy running-config startup-config or wr to save the configuration.

      Even with the command copy running-config startup-config, I can't save the router configuration. What should I do?

    I can't save the configuration even if I type wr and the other copy command...
    Please, is there a solution?
    Especially I want to do labs with several routers, so it's not practical to redo the work every time.

      Hi,
      I have a final study project with GNS3, so I must find a solution for saving.
      The solution is as follows:
      After configuring the router, you do a show running-config and copy the configuration (right-click --> select --> select the configuration --> enter), paste this configuration into a text file named after the router (e.g., R1.txt).
      And finally, the most important part:
      right-click on the router --> startup-config --> paste the path of the text file (e.g., C:\R1.txt)

      Best regards

      after doing a (wr or copy run star) you need to press a button on GNS3 (Save Project)

    Hello,
    Thank you Mr. Mexance Hermann for the explanation
    I followed it step by step but I find that the VLANs that were created
    the rest of the configuration (e.g. interface allocation etc...) disappears

    Thank you in advance
