Absolutely, I was more intent on reporting my mileage as opposed to
anything else. Re-jigging the BGP was the only real option open to me. Our
main issues are the circa 4000 PPP session these each terminate, traffic
volume and the crazy ACLs. I'm just hoping the removal of a lot of the BGP
overhead means they don't completely melt every time a BGP update comes
in...
