Let routers route and let switches switch.

Switches which are supposed to do routing never scale, provide almost always
immature implementations of common L3 features and run into capacity problems
just too fast (too small tables for firewall roules, route entries, no full IPv6
capabilities, sometimes expensive licenses needed for stuff like IS-IS...).

I understand the wish to keep broadcast domains small and network paths
deterministic and clean, but the switches you can buy today for
not-too-much-money aren't ready yet.

So my hint is: Look at model #4 from the mentioned NANOG presentation.
