Thank you Wido for jumping in, as always So far I only Have cloudbr1 as several VXLAN e-mail trails you indicated.
Then I need to create the cloudbr0 with another VXLAN in addition to cloudbr1 ? cloudbr1 should have the management per the video you posted right? Hope you recall, should I include in the VNI range the initial VNI/VXLANs i am using for cloudbr1 and cloudbr0 Thank you so much.
