Connecting the world…

About is a personal blog about Connectivity. Connectivity, in my opinion, covers everything about IT network infrastructures and all of its related components, like new software and/or hardware from vendors like Cisco Systems, Juniper and so on. Some blogs also contain useful configuration examples, at least for me, from different network components. I created this blog to share my knowledge with other people and hopefully someone will share his knowledge with me……

Booches is dialect for the place I grow up. The real Dutch name for Booches is Bocholtz, which is located in the southern part of the Netherlands. contains blogs about everything related to IT network infrastructures. Most of the blogs contain experiences of myself during my work.

But who am I…. My name is René Jorissen and I am co-owner and work as Solution Specialist at 4IP B.V.
