I know some folks that have implemented this and found that it worked
VERY well indeed.  Even in centralized portions of a Tier 1 network,
this tended to reduce the forwarding table by 20-30% and in edgier
situations it was more like 40%.  

It's well worth it, IMHO, and Cisco should take the opportunity to port
it to IOS.

$.02,
Tony
