I have a couple of simple questions regarding MPLS and would be appreciate to every help:
Is it stricly necessary that CE and PE (in MPLS terms) routers are directly connected? Or is it possible to create CE-PE interconnection via Internet connection?
what I mean is, let say we have an ISP provider for datacenter network (our responcibilty) and second ISP provider for office (office's ISP responcibility). ISP provider for office will sell us MPLS services and will interconnect all our offices (may be a good idea). The question is how we should connect our datacenter network to the office MPLS network? should office ISP install new physical link to our datacenter network or we can use public ip addresses to establish a CE-PE connection?
