HQ_Datacenter_TO_DR Switch
i have two fortigate which are clustered itother via HA in HQ datacenter , they are gateway of servers . now i am going to build DR site which will be remote office and where averything will be mirror of the main server room and these offices will be connected itother via LAYER 2 DARK FIBER (in server switches) . i need that when main office turned off for some disaster , DR office fortigate become gateway of my servers .
i thought that VRRP will be a best choice , but vrrp is not working properly . what do you think how can i build my topology , so that when primery office had down , DR fortigate will become active , is it possible to cluster DR Fortigate and main fortigates together? I have only one DARK FIBER OPTIC which is between server switches of HQ and DR
