Thanks for the quick reply. I figured it might be something like that. I have another question (just to ensure I've configured things correctly). My setup follows this topology:
Now, I've deployed my Edge appliances to hang off the VDS like the above. In this specific architecture, the Edge VTEP needs to be in the same vlan as the Host Transport node VTEPs (which I've done). While I can successfully ping between my Host Transport node VTEPs, I cannot ping from the Edge VTEP to a Host Transport node VTEP. Looking at things more closely now is this because I need to ensure the physical switch port (P0 in the pic above), the VDS and the Edge Transport-PG (vNIC2 in pic above - hosting the Edge VTEP) all need to be configured with Jumbo Frames (a minimum 1600 MTU)? Presently, I don't have JFs configured on my VDS uplinks or port groups.
Could that also be causing issues for N-S traffic (along with the need to ensure my logical networks are configured on my upstream router with a static route)?
