This is my application https://github.com/msgm68dev/my-ryu-public/blob/master/ryu/app/all_in_one.py which is a simple_switch_13 PLUS arp-proxy idea from here <https://github.com/muzixing/ryu/blob/master/ryu/app/simple_arp_proxy_13.py> PLUS simple logger functions for 4 events: EventSwitchEnter, EventSwitchLeave, EventLinkAdd, EventLinkDelete
This is my custom mininet topology: https://github.com/msgm68dev/my-ryu-public/blob/master/my-topology/wheel.py 1-Running Ryu: ryu-manager --observe-links ryu.app.all_in_one 2-Running Mininet: sudo mn --custom wheel.py --topo mytopo --mac --switch ovs,protocols=OpenFlow13 --controller remote and you are asked for number of vertices: If you enter a number <= 7: pingall works fine If you enter a number >=8: pingall will not work after h1!!! and ryu will show 2 floods of messages: 1. a flood of packet_in which because destination mac not found (line 146 in all_in_one.py) 2. a flood of LinkDelete & LinkAdd events (To see that, comment line 146 and enter a large topology wheel length like 25) Why this occurs. Thanks in advance Mostafa
