I'm adding an answer to the question as the supplier found the solution to the issue we were experiencing. I'm merely adding here his explanation, it could be useful to anyone else incurring in this event. Thank you again!

I found the solution that you need to add the Virtual MAC address on one of the interfaces of both EDR.
I got it all working now, here is the config:
ip address 10.10.0.1 255.255.255.0
ip address 192.168.10.1 255.255.255.0
ip address 172.16.0.1 255.255.255.0
router ospf 10
no passive-interface ...
You could try creating route maps to redistribute BGP to OSPF it also gives you more control over what is redistributed. The config below is from an Arista but you should be able to map it to a cisco. Ill try and spin this up in a lab as well and see what i can find.
route-map bgp_to_ospf permit 10
match ip address access-list bgp_to_ospf
RSTP interferes with your setup of routed links.
As far as I can extract from the manual, the EDR-810 cannot separate its switch ports or configure them as routed (L3) ports.
As a workaround, configure each port with a VLAN of its own, untagged. Then configure each VLAN like a routed port. Disable RSTP on those ports as well - when there's only a single port,...
