Here are a few ways MP-BGP/BGPv4 is fundamentally unique: Extensible: MP-BGP can store and run multiple address families (AFIs) and subsequent address families (SAFIs). …

So far, all examples to date have been extremely simple, and stand rather well on their own (OSPF Clos would work just FINE in a campus network if you have cheap L3) but may not effectively address some more advanced use cases. In short, we're about to enter niche territory. Generally speaking, BGP is regarded as the …

As covered in the previous post, base configuration of a spine-and-leaf fabric is actually pretty simple. This will be pretty short, but we'll cover the conversion of the previously built fabric to OSPF. Here's the updated diagram: (YAML). As we move to a more full-fledged implementation, we'll do dual-stack. The …

Before we get too far - this is going to be a simple topology, relatively speaking. I'll be putting the switch configs on my GitHub account as well when I get to that point. The diagram is as follows: This was drawn programmatically with drawthe.net. File is here
