      Hi,

      I created slice on which I want test load between nodes. I run example from your library, All was OK,  but finally when running iper3 I have got error. The Iperf3 client cannot find path to the server.  The ping between nodes was running fine.  Therefore I did some more experiments with running iperf3 manually from one host to another but the results was always same:

      iperf3: error – unable to connect to server: No route to host

      Last year in version 6 I run same example OK.  Therefore I went to Internet and found that iperf3 error is quite common running in  virtual environment.  How to fix this I do not know. Please help.

      I add all details into 2 files. The first is copy of Jupyter Notebook which I used with all results. The second file is copy of my activities on nodes which I have got.

      With best regards

      Jiri Navratil,

        Hi,

        I was able to run the notebook .

        Could you please share your Slice ID?

        Additionally, could you post your inquiries in the FABRIC General Questions and Discussion forum?

        Thanks,

        Komal
