You want to provide a OCI that keeps each data center routing domain isolated, while also supporting translation of VNIs. Which DCI scheme allows these features?
Understanding DCI (Data Center Interconnect) Schemes:
DCI schemes are used to connect multiple data centers, enabling seamless communication and resource sharing between them. The choice of DCI depends on the specific requirements, such as isolation, VNI translation, or routing domain separation.
VXLAN Stitching:
VXLAN stitching involves connecting multiple VXLAN segments, allowing VNIs (VXLAN Network Identifiers) from different segments to communicate with each other while maintaining separate routing domains.
This approach is particularly effective for keeping routing domains isolated while supporting VNI translation, making it ideal for scenarios where you need to connect different data centers or networks without merging their control planes.
Other Options:
A . MPLS DCI label exchange: This option typically focuses on MPLS-based interconnections and does not inherently support VNI translation or isolation in the context of VXLAN.
B . Over the top (OTT) with VNI translation enabled: This could support VNI translation but does not inherently ensure routing domain isolation.
D . Over the top (OTT) with proxy gateways: This typically involves using external gateways for traffic routing and may not directly support VNI translation or isolation in the same way as VXLAN stitching.
Data Center Reference:
VXLAN stitching is a powerful method in multi-data center environments, allowing for flexibility in connecting various VXLAN segments while preserving network isolation and supporting complex interconnect requirements.
