[c-nsp] question about service provider network design

[Nathan]

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 not using STP, instead
preferring point-to-point links. I don't have enough point-to-point
links, so what is better, creating an L2 square running MST, with the
square's top and bottom being WAN links, or creating two L2 networks,
each consisting of two switches (one at each of the two locations)
connected by one WAN link, with all routers having an interface
connected to both switches at its location?
