What software and hardware are you using?  If it's "the right stuff", 
there was a neat presentation at NANOG42 that showed a cool way to 
enforce peering policy on an interface, without having to dedicate a 
router to the task.  See http://www.nanog.org/mtg-0802/norton.html and 
view David Smith's presentation.  Admittedly, it's only on 12000 E3/E5, 
XR 12000, CRS-1, and "other IOS routers also"...which translates to "not 
in 6500/7600" unfortunately.

The concepts in the presentation are a little complex.  Just read it 
slowly, and read it again...it wasn't much easier with a narrator.  ;)
