The output of this tool can be used as baseline for other tools like Cisco, Juniper etc to verify their networks are in sync with each others or not!It also provides additional information about devices which was missing from cisco version! It has saved my days by allowing me compare two different versions of same device (which were out-of -sync) at one place!! Highly recommended if you want an easy way to understand your infrastructure quickly without having deep understanding/experience. I have been using it since last 3 years but never found any dislike so far until now when i mentioned that its price tag might scare some people off!! If there's no need then don't worry because free trial would work just fine. Its really worth going through even though small cost will make sure u save lot more time laterOnwards we're able to find issues easily without wasting much of.
