Help with SDA ntra-vn traffic on same site, different nodes on Cisco Practice Labs

[mountaintop2]

I can't figure out how to get this working.

Let's say you have branch 1 and branch 2. Branch 1 has one SDA node and branch 2 has 2 SDA nodes.

You set up your IOT, GUEST and EMPLOYEE VNs, with vEdges as your fusion routers.

The vedge in Branch 1 sees routes from both vedges in Branch2 in each respective VN / VPN. The vEdges in Branch 2 see the routes from the vedge in Branch1  in each respective VN/VPN. However, I can't get the two vEdges in branch 2 to share routes. I believe this is because they are in the same SD-WAN site, and by default they will not make connections to each other. Because the two vEdges are not directly connected, I'm trying to figure out how this is supposed to work.

Where and how do i leak these routes?
