Can anyone please advise on the following issue I am having with the multi-controller tutorial for VTN - L2NetworkWithMultipleControllers
Using the custom mininet script provided, I am able to connect to 2 controllers running in seperate Ubuntu 14.04 vm's, but when I try to create the VTN (vtn3 as per tutorial) it does not seem to work. Specifically, when I run through the commands in the tutorial everything seems fine, but when I query the status of vtn3 it is "operstatus:down"
I have confirmed that both Controllers/VTN Manager's are listening on required ports (6633(for mininet), 8282(for coordinator), as well as 6653 & 8181). I have also disabled the firewall's in both controller vm's (using "sudo ufw disable").
Incidentally, I have successfully ran through the single controller tutorial on the same servers/vm's without much issue. It is just the creation of the VTN in the multi-controller tutorial that does not work for me?
Is there any particular ports required on the VTN coordinator side? When I run lsof -iTCP | grep 66, or 82, I am not getting any response to those ports, although as I have already mentioned, the set up works for single controller?
Thank's in advance for any advice,
