Ryu spanning tree doesn't work when using --switch user #181

I need to use meters and spanning tree. I try using spanning tree from https://github.com/osrg/ryu-book/blob/master/ko/source/sources/simple_switch_stp_13.py

When I try it using ovsk switch, it works as supposed (some ports turn BLOCK, LEARN, LISTEN, etc) sudo mn --topo linear,3 --mac --controller remote --switc ovsk ryu/bin/ryu-manager ryu/ryu/app/simple_switch_stp_13.py

But, when I change to sudo mn --topo linear,3 --mac --controller remote --switch user ryu/bin/ryu-manager ryu/ryu/app/simple_switch_stp_13.py

It does work. Never stop sending BPDU messages.

Any suggestions.

Thanks

Any idea why Ryu spanningTree app does not work when using CPQD switch in a topology with loops?
