Routing between 2 different subnet #369

Closed catadros closed 3 years ago

catadros commented 3 years ago

I am new to using Mininet-WIFI and I have 2 strange issues happening

  1. routing between server1 and the rest of the network isn't working when using ping as test it told me unknown network
  2. I dedicate a specific position at the beginning of the simulation but when I plot the roads and RSU I found everything changed its place and the clients used are fixed I don't know why this happens if somebody can help, please

  1. First of all, I can see multiple controllers running on the same TCP port. Lastly, please make sure the routing table is correct and the controller has handover capabilities.
  2. Initial positions don't work for vehicles. By the way, I suggest you use SUMO (e.g. vanet-sumo.py).
  3. if you are new to using mn-wifi you should consider a more simpler scenario.

Ps. This is not an issue. Please use the mailing list for these questions.
