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?
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!
