[j-nsp] question about S/RTBH on DPC / MX's

I've been doing some reading getting ready to implement S/RTBH using uRPF.

Basically if i have a route in the FIB whose next-hop is NULL0 then
uRPF Loose will discard the packet if that route is in the SOURCE addr
of the packet.

What I'm reading seems to indicate that this is available on a MPC but
not on a DPC

Is this correct ??

Are there any work arounds on the the DPC ?
