FortiSwitch DC Design

[istvanmarlok]

Hi All,

I have a question regarding a FortiSwitch managed by FortiLink. We have two data centers (DC-A, DC-B), each with a standalone FortiGate. Under each FortiGate, there are two 1048E switches serving the servers. There is a dark fiber link between the two data centers, which connects the FortiSwitches.

Since there is L2 connectivity between the two DCs, I encountered an issue where the FortiSwitches from DC-B also appear on the FortiGate in DC-A (and vica-versa), prompting me to authorize them. Currently, I have set them to "Reject," but I'm not sure if this is the official solution or if there is a better approach.

Could you provide guidance on the best practice for this scenario?
