Hi,

Two issues I can see from the screenshot itself. First, the dot1q interfaces you have configured on the router are not in their respective vrfs. Second, BGP neighbours you have configured are in default vrf, You should configure the bgp neighbor under the vrf.

Are you using same VLAN for Transport node TEP and Edge VM TEP, relying on existing vSphere vDS? Different options are available but in this case you should create additional NSX segments (Vlan type) and allow required Vlans over that (TEP etc - maybe trunk allow all is easiest option in lab) and attach Edge Nodes uplinks to these segments respectively. After that you can configure T0 interfaces and rest of VRFs like you already started.

I experienced similar error without VRFs, but logic is the same.

HTH,

Dragan
