We do this to a very small extent, like when we want a router to only learn a specific set of routes because it shouldn't be forwarding traffic to any other destinations, e.g., announce only the prefix that our NOC lives on to the blackhole routers since all those routers do is signal RTBH routes, and don't need to see any other (internal) routes. Communities are powerful. Mark.
