What do you think would be a good minimal change to clarify? How about changing the word "duplicate" to "redundant"?

OLD:
   Duplicate BGP Large Community values MUST NOT be transmitted.  A
   receiving speaker MUST silently remove duplicate BGP Large Community
   values from a BGP Large Community attribute.

NEW:
   Duplicate BGP Large Community values MUST NOT be transmitted.  A
   receiving speaker MUST silently remove redundant BGP Large Community
   values from a BGP Large Community attribute.
