openflow.discovery:link detected: ; WARNING:openflow.of_01:<class 'pox.openflow.PacketIn'> raised on dummy OpenFlow nexus ; openflow.discovery:link timeout: pingall 100% dropped

Hi RouteFlow Group.

I have already made custom topology (7 switches and 5 hosts), in OSPF,

but i've been failed to pingall (use script edited from rftest2-script), it's 100% dropped.

i don't know what should i do to make it works, may be you guys can help me to solve this problem.

I've analyzed the output from my rftest4 file (run sudo ./rftest4) and also in my topology in mininet.

I found something strange in my output, but it's just my feeling...... These are a few parts:

....

But when i run pingall, the output in the routeflow still running, like these:

Hi

I mean what i want to ask:

For example I want to connect switch3 eth3 with switch7 eth3.

But in the output, i found that switch3 eth2 connected to switch7 eth2

 INFO:openflow.discovery:link detected: 00-00-00-00-00-03.2 -> 00-00-00-00-00-07.2

And in the end i found the link has broken, right? INFO:openflow.discovery:link timeout: 00-00-00-00-00-03.2 -> 00-00-00-00-00-07.2
