Connecting xcp-ng cross datacenter


I am trying to link several xcp-ng VM from different datacenter and I understand that I need to use GRE/VxLAN tunnels.

I have been trying to understand the difference between the 2 but I an still confuse with both network.

Could anyone please advise on the best network to choose to bridge the datacenter together?

Thank you

The requirements are listed here: (Take note of the MTU requirements)

They have the topology here

Thank you fir the links. I have read these 2 pages but what I am not sure is in what case do we. Use GRE or VxLAN?

What are the use case?

Try both and see which works best for you. I just did that and didn’t notice a difference. Either way, it’s pretty slick!
