A customer on-premises location is connected to both the Serbia Realm (eu-jovanovac-1) and the Frankfurt region (eu-frankfurt-1) in our Commercial Realm. The connection process for the customer involves the following key points:

• Use a third-party telecom provider to provision Layer-2 connectivity from the on-premises CPE1 all the way up to the Oracle Edge Router in the Oracle FastConnect location in Serbia.
• Use a third-party telecom provider to provision Layer-2 connectivity from the on-premises CPE2 all the way up to the Oracle Edge Router in the Oracle FastConnect location in Frankfurt.
• Establish a Layer-3 BGP peering connection from CPE1 to the Oracle Edge Router in the OCI Serbia FastConnect location.
• Establish a Layer-3 BGP peering connection from CPE2 to the Oracle Edge Router in the OCI Frankfurt FastConnect location.
• Provide Layer-3 network connectivity inside their own network to allow traffic from the Serbia OCI Realm to reach the Frankfurt region, and vice versa.
