[nsp] Routing Architecture

Hello,

In a typical service provider environment say one that provides
co-location services, how would one propose the routing architecture ?
The last one I saw divided their networks into subnets VLSM etc.. and
mixture of private and public addressing with *static routing* at the
core. Of course, BGP4 is the external routing protocol.

OSPF at the core and static at the edge seems one good alternative. I
would not like to run OSPF totally because I might want to use private
IPs for back-end servers and reserve public IPs for internet access
only.

Any one has a better real life experience to share would be appreciated.

thanks,
