I work for a small ISP. For the past few weeks things have been running slow on the network. After working on and off of the problem for some time will no fix, I had to take a break from the problem. So I setup a VM running centos, I installed your software (the rhel howto has some mistakes). I then added the core switches and routers, 9 devices later I had the core mapped. After the software was running for 10 mins I started to see a problem. The core router that links up two ISP with BGP was having interface errors. Comes to find out the interfaces was running at half duplex. After fixing the duplex error the network came back to life. I would like to say thank for the software and I am a kickstarter supporter.
