if I have a 75xx router with 300 ethernet ports, and I bridge all
those
ports, do I have an L3 switch, or a router?

Oo
good for you, Cil. This discussion was ( and still is, to judge from my

This might help. What does the V stand for in VLAN? Virtual. VLANs are a
method for emulating Real LANs in a switched network. The original poster
seems disillusioned with VLANs. Well, I am too. :-) You can't do much with
them that you can't do with a bunch of Real LANs connected by routers.

I've been following this thread, and have offered a comment or two along the
way. Perhaps I should offer some thoughts here at the source.

don't know what is or is not being stated in the courseware. I can offer

It's true the contrary case: the Vlans requires L3 to be routed, or, in
other terms, to comunicate each others. The L3 switching has no sens without
