hi! i understand that the ideal setup of a new network infra is in the Hierarchy Network Model. (Core--->Distribution--->access).
My question is that since, all the routing is done in the distribution layer (eg. 45xx L3 switch) with the L2 switches connected to these L3 switches, why do i still need a core layer switches (eg. 65xx)?
From reading, i understand that, it's a good pratice to have the core to do the switching and L3 switch to do the routing, but i'm not sure how's the config like. Please advise. Thanks.
