Hi,
I have a 3-fully-collapsed cluster (3 hosts for transport, management and edge). I noticed that Geneve tunnels between the transport nodes and the edge node don't come up from two of the transport nodes but they do from one of them!!!
I use the same layer-3 segment and same VLAN ID for VTEPs for the host transport and edge transport nodes. I read a lot of documentation, communities and blogs where all say that you cannot share the same VLAN ID for the host and edge transport nodes IF you use the SAME virtual switch in the host for the VTEPs host itself and for the edge VM's VTEPs. But that is not my case. My three hosts have 4 physical vmnics (0 to 3). I use a N-VDS that uses two physical vmnics (2 and 3) for the host transport node's VTEPs and another vSphere DVS that has two vmnics (0 and 1) where the Edge VM is connected. So, I thought I could use the same VLAN ID for all the VTEPs. I'm not sure if this is actually the problem why the Geneve tunnels don't come up from two host transport nodes but they do from one of them. It is supposed that if the same VLAN ID for the VTEPs was the problem the tunnels wouldn't come up from one host and don't from the other two. Am I correct?
Just a pair of images where you can see that from one host they come up and from other one don't.
Does anyone know why this could be happening?
Thank you advance,
Guido.
