There are lots of options but beware of the MTU.

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?
 
Philip
