Interconnection between 2 data centers?

[sikhanegi08]

I have 2 pairs of Nexus 9ks and two fiber links between 2 data centers. As of now, I'm doing layer 3 (OSPF) between these 2 data centers for interconnections. I don't want to go to the ACI route; I'd like a simple VXLAN solution for the 2 interconnections between 2 data centers. Would it be possible to go VXLAN route and remove OSPF? And what would you do in this case?
Thanks.

Hello @sikhanegi08 

You need L2 extended vlan on your 2 DC ?

Hi,

   You can have it both running at the same time, one doesn't exclude the other. Here's some good references to guide you, as I don't have the complete picture of how your network looks like and what are the associated dependencies:
