2009-09-21 Thread Ric Moseley
Does anyone know of a tool/script that can aggregate subnets feed to it via command line? Meaning if I give it multiple /30s (or any size subnet) it will scrunch them together. Example: #aggregate_subnets.script 192.168.0.0/30 192.168.0.4/30 10.0.0.16/29 10.0.0.24/29 #192.168.0.0/29
