MPLS VPN // OSPF as CE<->PE protocol

Hi Everybody!!

Can someone provide any insights about an scenario where the backdoor link
is a non-backbone area and it's not on the same area than both CE-PE links,
so I wonder what would be the best solution so the MPLS backbone is used as
primary path from one site to another.

1- Should I extend the area 10 to the PE 1?

2- In other hand, do I need the PE to have an interface within an area to
create a sham-link for this area?

[PE1]----------------------------------[PE2]

Area 0 Area 10

[CE1]-------------Area 10------------[CE2]
