Hi again,
Since Marko says my question wasn't clear I'll try to make it better :-)
- Is running OSPF on a switch at all useful when the switch is
connecting routers that are running MPLS, MP-BGP, and OSPF? Can it
provide faster detection of link loss?
- In a campus scenario, Cisco recommends

The routers can see each other directly at L2?

Well, the switches aren't important here, so if you plan to do ipv6 in the
future and aren't a huge ospf fan,
have a look at isis now and switch if you like it. It's definitely a lot
easier to manage and troubleshoot.
We have a fairly similar design for our Metro Ethernet network.
Our primary method of protection is STP(MST). I've been thinking about
this, and I can't come up with a reason why we even really need an IGP
down to the edge PE devices? Since it's all layer2 - the core

So say I have an SVI on a PE switch which in turn has 2 layer2 links
back to 2 core boxes, the core boxes protected again by a 3rd layer2 link.
MST will protect me and make sure I always have link to the PE routers

Hi,
I'm re-designing a service provider MPLS network, and I'd
appreciate some macro-level input.
I have two major sites connected by two gigabit WAN lines. I
have or will have about a dozen Cisco switches (3508, 2960,
3548, 3550...), half a dozen C7206s for customer termination,
four J4350s for
