Hi there,
This post just to share my experience on a little issue observed in VCD-SP 8 after an upgrade from NSX 6.1.4 to NSX 6.2 in my lab.
My lab consists of :
vSphere 6 u1
vCD-SP 8
NSX 6.2.0
In NSX 6.1.4, i had prepared all the logical network settings but the Multicast addresses as i did not want to use it. I was then able to start any of my VCD vApp.
When i upgraded to NSX 6.2 i had not tried to start my VCD vApp for a bunch of reason (i had some other stuff to deal with).
So yesterday, around one month after the upgrade i decided to start some vApp. What a big surprise !!!! Just look at the following screenshot
vcloud-container-debug.log talked about universal edge settings.
All that first led me to think about a compatibility issue between NSX 6.2 and VCD-SP.
I then double checked the VCD-SP error and noticed the last line. I finally understood that my problem were due to my multicast settings... which were NULL
I typed something and tried to start my vApp, BINGO !!
MY QUESTION HERE :
WHY MULTICAST ADDRESS SETTINGS ARE MANDATORY EVEN WHEN MULTICAST WILL NOT BE USED !!
I assume that is to prevent configuration issue if we change our mind and decide to use multicast as replication mode but is there any technical reason ?
