I really enjoy discussing network design and deploy details with colleagues, customers and fellow network engineer. I find these discussions challenging, stimulating. An open, sincere and collaborative discussion gives a chance to better understand the real needs, fears, doubts of other professionals and to validate knowledge, expose gaps and most of all I learn a lot. This is still valid when discussing Data Center design or simpler topics like how to cable switch stacks.
I’ve been working on a data center migration from regular switches to a Cisco ACI fabric in the last couple of months. I can’t say that’s enough to be defined as an ACI expert but I’ll share here what I learned from the experience. The project started with a Network Centric approach for an one-to-one migration from the previous network. After the migration new VRFs are being created in App Centric mode with contracts.
