Wait, isn't that the same as option B, Ordered control mode? I'm a bit confused here.

I think it's option E. Downstream on demand label distribution mode, since it only propagates a label mapping for the FEC's next-hop.

I'm not sure, but I think it might be C) Liberal label retention mode, as it also propagates label mappings for all FECs.

I agree with Mila, because in Ordered control mode, a router only propagates a label mapping for the FEC's next-hop.
