Explanation

Option B is correct. Filter-based forwarding (FBF), also known as Policy Based Routing (PBR), uses the forwarding routing instance type. Option C is correct. Routing Information Base (RIB) groups are used to copy routes from one routing table to another. In the context of FBF, RIB groups can be used to copy routes from the inet.0 routing table. Option A is incorrect. FBF does not use the no-forwarding routing instance type. Option D is incorrect. RIB groups are not used to hide routes in the inet.0 routing table. They are used to share or copy routes between different routing tables.
