Additional Endpoints in In-Band-Mgmt BD

Hey all  

I am trying something that is maybe a bit strange, but it would safe me an L3Out and assigning some additional subnets..

I have a Nexus Dashboard and a very small ACI fabric (no other Nexus switches anywhere) and subnets as well as additional links for additional L3Outs are in short supply.
Since the Nexus Dashboard (Data Ports) will never have to communicate with anything other than the In-Band IPs of the small fabric... a quick idea I had was to move them into the In-Band Management BD.

It is possible to manually create EPGs in the mgmt Tenant and assign those EPGs to the inb BD.
I did that .. moved the data ports to my new EPG and they can flawlessly ping each other (with IPs within the Subnet of the inb BD).
They can also ping the gateway (IP of the inb BD).

However I fail to establish reachability between the In-Band IPs of the Fabric and the Nexus Dashboard.
I added a contract between my EPG and the In-Band-Management-EPG allowing all traffic  

Any ideas?

Thanks a lot and BR
Jules
