We have an architecture utilizing the VVD wherein the T0 edges are nested (provider and tenant T0).
Physical Network > Provider Edge Cluster (T0) > Tenant Edge Cluster (T0) > Tenant Networks (T1)
This works really well with our automations, routing, and segmentation. However, we have discovered some traffic routing we want to improve. So, we have been testing how to setup a T0 with only overlay (no VLAN) interfaces. This is to keep the Provider and Tenant (T0) transport traffic in a linear flow.
Does anyone know of a method to deploy the edges in such a way? Would a transport zone per transport network solve this?
Yes, you can use overlay interfaces (external) for T0 as well. As you have highlighted, scope the Transport Zone correctly and enure we use the same while creating the segments for uplink connections.
Sorry, haven't been on here in a bit.
When we try, the interface selection form doesn't present those overlays.
Please ensure you are using the correct overlay Transport for the segments.
