Subject: Layer2 over Layer3

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?
