Hi Diana! Nice to hear from you. Yes, i have run pox.py forwarding.l2learning.
But I don't know why i still cannot make the two computer hosts ping each
other. Can you explain it in details? Thank you!
Rebecca.

Rebecca,
In POX forwarding.l2_learning component is implementing a L2 learning switch,
and you have there example of how the flow is installed. Also the code is
commented and in the same folder (forwarding) you will find some step-by-step
tutorials and a L3 learning component.
Start from there :) Good luck!
