Two routers would be the better approach. You have equipment redundancy, plus redundant service providers.

Am I missing something?

I 100% agree, I just wanted to make sure I wasnt missing something....

Adding to this,

What are your feelings on what I will call a "data center switch design"

Single "end of rack switch" Lets say 6500 with redundant supervisor cards.


Two redundant "core" switches, each with a link to each "top of rack switch"

I like the latter, but again just wanted some opinions.

I would always go with the dual chassis approach over the single chassis with dual SUPs, if the budget allows. I think its pretty straighforward.
