Configuring BDI
The BDI interface on router side that is used for module and router traffic is Layer 3. To prevent loops
from occurring when more than one module is configured with same bridge domain interface, you must
configure the same bridge domain with split-horizon to stop the traffic flow between the two modules
as shown below:

You can also configure the layer-3 features in BDI interface.
