I'm not saying it's bad solution, I know lot of people do it. But I think people only do it, because L3 at port isn't offered by vendors at lower rates.
A lot of people did it because because there really wasn't a cheap, dense solution until about 2010. And even then, the traditional strategy had become so entrenched that running IP all the way in the Access was such a foreign concept which was most certainly a lot more expensive than incumbent Layer 2-based Access models. I feel this has since changed with the current offerings from Cisco, Juniper and Brocade. The problem now is how to scale the low-speed port density up, as well as add 10Gbps port density, without increasing the cost or size of the platforms. Mark.
