It is ture that practice is very important for CCIE Certificate study. Howerver, the lack of a right tool and the absense of a approachable lab network become some trouble for the guys who need practice.

Today I recommend a tool and a suitable lab netwok for the guys who need it.

NetBrain Operator is a pretty cool tool and has integrated a lot of powerful network features, such as network diagram, network troubleshooting, network design, etc.

You can use NetBrain Operator Edition to learn each CCIE knowledge points, for example, you can compare any two configure files side by side and you can figure out the subtle difference between any two route tables. For more details, click here: http://www.netbraintech.com

As a network engineers and CCIE practicer, you can try the tool and then use this lab network to help your study. To get an instant trial, click here: http://www.netbraintech.com/instant-trial/
