Routing policy question.


RFC 2772 says that you can only to your upstreams your fully aggregated
prefix, but it doesn't tells what to advertise to your downstreams.

(From 4. :)

   All 6bone pTLAs MUST NOT advertise prefixes longer than a given pTLA
   delegation (currently /24 or /28) to other 6bone pTLAs unless special
   peering arrangements are implemented.

("to other 6bone pTLAs" does imply that this is not a requeriment when
talking to a downstream?)
