For the IOS I'm using for my lab 12.4(20)T, it's necessary to configure BGP address-family MDT for the MDT tunnel to come up.
Otherwise everything else in this lab is straight forward. Configure Multicast throughout the SP and Enterprise devices, enable Multicast on the PE's for the specific VPN and if using static RPs remember to configure the RP address in the VRF on the PEs.
