MPLS and OSPF Area 0 Hierarchy

Group:
I need clarification on how area 0 is maintained across MPLS networks between customer network. Some of the example I am going through right now are something like this:
CE1(OSPF A1)--(PE1)--P1---P2--CE2(OSPF A2)

OSPF (in area 0) is running on SP network (only). Now in a typical DMVPN environment, Area 0 is maintained across the WAN for each site of the customer.Area_1--site_1---Area_0---site_2--Area_2.
How does it related to this Area 0 concepts?

ThanksKhalid
