Bridging directly over a GRE tunnel is not supported (but the other
options are valid). Of course, you could do EoMPLSoGRE, if your
platform supports it, but not L2 bridinging directly over GRE.

HI Vineesh,
You have a few options (MPLS AToM P2P circuit, L2TPv3 P2P circuit or
even bridging over a GRE tunnel).
Since I suspect you don't have an MPLS network in between the two sites,
you're probably better off reading about L2TPv3.
Please keep in mind the MTU issue as you're going to transport L2 frames
and unless your routers can support higher MTU on the inter-site link,
they'll have to start fragment the L2TP frames - something that can
affect your perfomance, depending on the circuit bandiwidth.
Regards,
Rado
