Please help my project

Hi every one I got a project from my boss (we're the ISP in this country) and he told me the customer have 2 branches in this country and 1 on USA and 1 Singapore.  We need to use wan single subnet or like broadcast multiple-access. How can i do like that with the different ISP if they cannot provide same vlan.

Thank you and apologize for my English.

You can use MPLS over GRE tunnels to get to the remote routers on the remote service providers networks, and use VPLS to bring it all together.

Since there are only two remote locations, it might also be just as easy to use L2TPv3 psuedowires over GRE.
