Maybe see if you can find a Cisco CCNA study guide to flip though? Here's a syllabus [0]. This will give you a good foundation in layers 1-4 and routing, but stops short of bgp. You can tackle bgp separately, afterwards. Routing with bgp can get tricky, it's a bit different in that it sits on top of other routing protocols, routing between separate routing/admin/policy domains, not devices. Routing can be a lot of fun. Keep it simple to avoid surprises! For me it was a while ago, but the cisco material explained how things worked at a packet/protocol level, and that "clicked" for me, things like how a host finds a router, how routers find each other, how routing protocols build a map of the network, etc. There are well defined protocols for all of this. The cisco study material did a good job of explaining all of this stuff. The CCNA is the introduction, and there's other study guides going into greater depth on various networking topics. The nice thing about networking is that once you know the concepts it's not difficult to move between implementations.
