The correct answer is B. Configure data MDT in the VRF on PE2. While the default MDT (configured on PE1) carries auto-discovery and control, the actual IPTV multicast stream is carried over a data MDT P2MP tree. PE2 must have a data-MDT configured in the same VRF so that it will join the mLDP data tree and forward the 232.1.1.17 stream down
