Is it just Layer 3 switches like Nexus and 65xxs that have IPs on every SVI all running an IGP? for instance?
What differs a "Layer 3 only" network from a Layer2/3 network when it comes to deployment, exactly?
To be clear, if I logged onto a random switch in a DC, what would be the giveaway that it's a layer 3 only network? I was having a meeting today and someone mentioned getting rid of STP and replacing it with MPLS to create a Layer 3 only network and it got me thinking what exactly that would look like. Since MAC addresses are clearly still in use for local node access.
