Yes, a single device can represent the core and distribution layers. That's
your typical collapsed core. However, what of a link between two collapsed
core devices. If it's not a trunk link, how does it carry traffic that
originated in a VLAN? How do you truly terminate the VLAN at the
distribution layer?
I've got an idea, but I just can't solidify all the pieces currently.
I eagerly await Tony's answer.
