in CCNA & CCENT
Does the core layer have to be switches? Or can it have routers as well? I'm a little confused as to why the core layer, from what I've been reading, uses switches instead of routers...can someone help clarify a bit? thanks

Layer3 switches that can do routing internally, a router is usually at the edge connecting remote sites of the network,
the core layer is usually at the local site routing traffic accross the other multiple distribution layers.
so for example
computers---->access layer switch--->distribution layer switch
> core switch
>distribution switch
>access switch---->Server
or
computers---->Cisco 2960G
>Cisco 3750X
>cisco 6800
>Cisco 3750X
>Cisco 4948E-F or 2xL2 3750X
> server

Layer 3 Switches are faster than Routers as they perform many of their functions (Switching, ACLs, etc...) on Hardware instead of Software. Unfortunately, L3 Switches generally lack features needed at the network edge (T1-Based WAN, BGP, NAT, etc...)R&S: CCENT → CCNA → CCNP → CCIE [ ]
