Hi, i assume that you have directly connected backbone (fiber) between 2 networks. if i understood correctly. in this case, if you are using same VLAN and network ranges at both sites, you dont need to configure routing protocol to do routing. because both core switches are connected with L2 link. you can configure backbone as a trunk and allow VLANs you already have. also, in this case you have to use 1 switch as a L3 switch with SVIs for different VLAN gateways on inter vlan routing purpose. please correct me if i am understood in wrong way.
