Hi, simple_switch or (simple_switch_13) does not depend on stplib. https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch_13.py Please investigate why "your" simple_switch requires stplib, first.
simple_switch_stp or (simple_switch_stp_13 on Ryu-Book) depends on stplib, do you mean this? http://osrg.github.io/ryu-book/en/html/spanning_tree.html#executing-the-ryu-application Thanks, Iwase On 2016年08月21日 00:56, Francesco Murador wrote: > Hey another question in my application i want an istance of simple_switch but > when i try to instantiate a simple_switch i can't because it gives me > keyerror stplib so how can instantiate a simple_switch object? > > Inviato da iPhone > >> Il giorno 17/ago/2016, alle ore 03:02, Iwase Yusuke >> <iwase.yusu...@gmail.com> ha scritto: >> >> Hi, >> >> Sorry for the delay. >> >>> On 2016年08月10日 17:59, Francesco Murador wrote: >>> So i don't need to do anything in mininet just add that in ryu?
