I've specifically heard from people who have tested it (which hasn't been 
me, so far) that SRB/SRC added something in addition to the netflow 
enhancements in SXH/SRA so that TCAM overflow is dramatically reduced. Are 
you saying that isn't true at all, or just that this specific detail isn't 
true?
