Over the years, whilst designing and managing large core MPLS networks, I have found it frustratingly hard to explain MPLS to fellow engineers, sometimes it would lead me to wanting to jump out of the window!
It can be hugely frustrating to be able to understand something and not be able to explain it in the same way.
But… what can you do? MPLS is that complex subject and when the likes of MP-BGP and IGP protocols such as IS-IS come into play, it becomes an absolute mess to simplify.
In fact, for many years, I just left myself believing that there is no easy way to explain this. It’s only when I was designing a MPLS network for a customer this year that I stumbled upon this idea to explain MPLS in the form of a triangle with IGP as the base and BGP and MPLS hanging on in the form of a dependency.
The result was a simple conversation with this logic would make life easier for engineers trying to understand and make sense of a MPLS network running BGP with an IGP such as IS-IS or OSPF.
I then decided to make a video to share it with you so that you can use this logic too in order to understand core MPLS networks in the same way and also use this to simply large core networks whenever you need to, be it job interviews or at work or wherever!
I am so excited to share my latest video simplifying MPLS and its relationship with BGP along with the frustrating question as to why the heck do we need an IGP?
