In a deployment of NSX-T 2.3
MGR, 3 Controllers, Edge Cluster (2 Edge VMs), Tier-0 and Tier-1 router.
All seems to be working ok (internal routing between subnets within the environment works fine) but when I add the UPLINK for the Outbound traffic, the SR0 drops it's internal 169.x.x.x address and no outbound communication is possible. I have tested this roughly 6 times and can literally watch the IP disappear when the uplink is added. I then have to delete all the Routers and re-create. From the DR, I can get out to the physical network but not from the Tier-1 router once the uplink is created.
