How to set up routing for DC Inter-Connectivity ?
Since the Inter DC network is provided as a wide-area L2 network, it is necessary to set static routes for both the logical network and the DC network.
Since the Inter DC network is offered in the point-to-multipoint type, it is possible to connect from multiple regions to one DC-to-DC network.
Please set up a static route in each region.
Please refer to: Service Descriptions -- DC inter-connectivity, "Static Routing Functions".
