For Question No.2 ... If you use the Open vSwitch, the STP app dose not wrok well depending on the OVS's settings or version. OVS has the STP implementation, but when this option is disabled (by default), OVS drops the STP (BPDU) packets with the dest mac address "01:80:c2:00:00:00". For only executing the STP app, you can avoid this constraint by modifying the source code as follows. ryu/ryu/lib/packet/bpdu.py: --- # BPDU destination #BRIDGE_GROUP_ADDRESS = '01:80:c2:00:00:00' BRIDGE_GROUP_ADDRESS = '01:80:c2:00:00:0e' --- Then, please affect the modification by the following commands. --- $ cd ryu $ sudo python setup.py install running install ... ... running install_scripts Installing ryu-manager script to /usr/local/bin Installing ryu script to /usr/local/bin --- > 3.
