If hardware is all the same, what's best practice for OSPF cost?
Egress and ingress are opposite of one another. (Egress/Ingress are not on the same connection) I like this setup, but i'm not sure if its best practice compared to the far right picture. I prefer this idea because inflow/outflow aren't shared on a link, but is this enough justification to be BP?
Each core will be responsible for their "side". (Left core/distro vs right core/distro) Not sure if this is correct...i'm just guessing
Primary/Secondary setup. (Left core takes care of everything, Right Core is backup)
