Unable to route traffic through 2nd VLAN uplink

I am trying to add a second uplink (different VLAN) to my NSX-T 3.0.2 with ESXi 6.7 environment. I am able to route traffic just fine out the initial VLAN uplink (ls-vlan-uplink > vmnic2), but nothing seems to pass on the second VLAN uplink.  Is a direct association required between the vlan logical segment, ls-vlan-perf, and the T0 router? See diagram

  • Are you saying you would like ls-vlan-perf to traverse only vmnic3 and ls-vlan-uplink to traverse vmnic2?
  • Are you pruning VLANs in your network?

In general, if you want egress traffic to work, then the tagged VLAN backed segment needs to be configuring as an uplink interface on the T0.  It is the way the logical interfaces map to the physical network.
