Well, this is not exactly true.    AT&T does support BGP communities,
although their communities aren't all that powerful, IMO.   To my
knowledge, you are correct when you say that they do not support any
null-routing capabilities.   I would love to find out the procedure
and string required to request/implement null routing via a community.

For those who would like to see AT&T's official guide, it can be found at:
