First of all I would like to thank you for your feedback. I do this on purpose to build a solid understanding of the technology without cluttering the mind at the outset. At the same time, I also want to avoid covering features that are seldom used in the industry but can be configured on the devices. I try to minimize on the coverage of these less popular features so that you can learn a technology in a more time effcient manner.
Having said that, I am planning on going in more depth about a topic in my Monthly Bootcamps that will be Lab focused. For these bootcamps, I am working on integrating these technologies with each other to cross the different CCIE tracks giving students a real-life perspective of an End-to-End solution. For example, implementing a SD-WAN architecture with MPLS VPN configurations and placement of firewalls in front of the Controlles and WAN Edges.
I also have the forum specifically for this reason to discuss more details about the tecnology not only with me but also with your peers in the industry.
Finally, we are also planning on introducing “Office hours” to cover doubts where students will have access to me live. This is available for KB Full Access Students.
Hope this helps.
