I did some further testing. In short, if I attach logical network/VLAN 103 to enp96s0f0
the network will come up and be available for use. If I attach VLAN 103 to enp96s0f1 the
logical network never comes up.
I have sort of answered my own question, though I don't fully understand why.
If my memory serves me correctly, I had used the exact same router setup on my 4.2.7 Ovirt
node. I believe I was able to use VLAN 103 on either interface without issue. Is there
something different about 4.3.6 Ovirt node? Is there some sort of rule that won't
allow a logical network to be shared with the same interface as the interface for
storage/gluster?
