DPSET: Multiple connections in Ryu SDN Controller -

-

i install latest ryu controller pip install(python3) in ubuntu 14.04 on vm(vm-a), , nic configure bridge mode(192.168.88.252).

i assume vm-a's host "host-a"

and connect physical zodiac fx openflow switch, port4(reserve connect controller, 192.168.88.252) router(192.168.88.0/24)

zodiac fx port3 connect router(192.168.88.0/24)

and connect 2 rpi(aka host-b,c) on zodiac fx port 1,2(so, 2 rpi 192.168.88.250, 192.168.88.249)

and connect controller host-a router(192.168.88.253)

it work fine, , 2 rpi able connect internet.

host-a able connect 2 rpi. if trying use vm-a kind of connect 2 rpi.

hole controller stuck few minute, message:

dpset: multiple connections {dpid}

i wounder know there illegal when using sdn controller communicate openflow networking devices?

in case, ryu app run simple_switch_13.py.

thanks!

if spread subnet(192.168.80.0/24) sdn switch communicate controller.

this problem solved!, sdn controller need nic connect subnet.

i still can using sdn controller access 192.168.88.0/24 without dpset problem.
