SDA Multi-Site (Fabric) with Dedicated DC

fatalXerror
Level 5
Level 5

Hi SDA Guys, need help. 

I have four (4) fabrics with their own Border Node. I also have two (2) small DC in traditional network. I also have Transit Control Plane Node to facilitate the SDA-Transit between my four (4) fabrics. Lastly, all of these fabrics and DC are interconnected using Dark Fiber.

The question now are,

1. Should I place a Fusion Device at my DC to facilitate the communication to outside the fabrics?

2. I am thinking another option related to question 1 is to place a Border Node at the two (2) DCs so that the DC can also participate in the SDA-Transit? Though I am not sure if it is feasible. So that, for example if fabric 1 wants to communicate to DC1, fabric 1 local BN checks my Transit Control Plane (TC) and the TC should know the subnet of the DC1 and which BN should it be located so that fabric 1 can send it to the DC1 BN directly.

Need your expert advise. Thanks

Its all depends how these  dark fiber terminated on what device, if they are directly terminated - then you can use SDA-Transit
