Removing and ignoring are obviously different things…  The text above is fine with me, but I would ask: what do the current implementations do?  If they remove (as originally specified), then I would suggest you keep that.

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.
