I dunno if they still offer it, but I found that Cisco's ICND1 was fairly neutral. They use examples from Cisco stuff, naturally, but the majority of the content is around learning and understanding how IP networks function. This is the first half of the CCNA study materials, and honestly, one of the best resources I had, and used, for learning how it all works.
There's probably a ton more out there now, but at the time when I was learning, it was all CBT Nuggets and pluralsight.... I believe a lot has hit YouTube in recent years.
Don't worry if the information is out of date, this stuff doesn't change. The updated stuff just has newer vendor specific information, and IPv6.
IPv6 isn't crazy different in how it behaves, but the mechanisms for local discovery, IP assignment, and whatnot, can vary quite extensively.
Good luck out there
Thank you so much!
