Extend VLAN across WAN

[johnnyenglish]

My company has 3 sites with point to point connections. These are configured on the routers as layer 3 interfaces. We want to extend a couple of VLANs (VLANs 10 and 20 at site 1 and 2, (VLANs 30 and 40 at site 1 and 3) and we will also be virtualizing our routing tables. My question is, how can I extend these VLANs? Should I use MPLS between the core routers and use EoMPLS and if so, are there any issues with each router essentially being in the PE role?

Thanks

You could take a look at this:

Why not just route? is there a technical reason to extend VLANS?
