L3VPN with L2VPN as backup

Hello, i have the following scenario:

Customer A has 6 locations all connected via L3 MPLS SP cloud. The customer recieves OSPF external type 2 routes from each location (well from PE router after MP-BGP VPN header is stripped and routes from 1 location redistributed into OSPF).

I want to provide the customer with a backup solution using an SP L2 VPN solution. If i am correct, when i connect the 6 sites via the L2 VPN, they will start to prefer routes to each other via the L2VPN (as they are recieving OSPF intra area routes from the single VLAN now connecting the sites.

My question is what is the best way to make the L2VPN be used only as backup to the primary L3VPN?

hopefully i have explained my situation clearly!

Thanks
