Layer2 over Layer3

[Philip Lavine]

To all,
 
I am trying to extend a layer2 connection over Layer 3 so I can have redundant 
Layer connectivity between my HQ and colo site. The reason I need this is so I 
can give the "appeareance" that there is one gateway and that both data centers 
can share the same Layer3 subnet (which I am announcing via BGP to 2 different 
vendors).
 
I have 2 ASR's. Will EoMPLS work or is there another option?
