I'm not entirely sure I follow you and/or I've made myself clear. I 
understand how to inject the RTBH routes and attach a community.

The issue is that I'm trying to get many (20+) RR clients to honour the 
RTBH BGP routes *inside* an L3VPN routing instance. I can override the 
next-hop at the RR client, but that involves touching a lot of routers.

I'm asking if I can override the next-hop on the 2 RRs, which is 
currently failing because the RRs are refusing to emit the route, as 
they can't allocate an MPLS label (even though the label will never be 
used).

So, what I'm asking is: how can I override an inet-vpn next-hop at a 
route-reflector, when the next-hop is not a "real" PE.
