Hi Robert,

 thanks for reply. Currently I am just looking for a way to bring it up for
internal trial, so if Quantum is better I will move to that. The only
reason that I am still asking for questions about nova-network is because
of the document order: I am setting things following the install document,
but when it comes to the network part I encountered above confusions. I
will check the quantum document to see if anything can be simplified.
Thanks again!

best
Yan
