The more paths you receive from different sources, the more likely it is that this list of 120k "superfluous" prefixes will converge towards zero.
Agreed that small numbers of paths are most unlikely to create the conditions for this problem to occur.
If these compression schemes are implemented, and our compressed count is near the limit of hardware, it creates interesting new attack vector for attackers. Pump carefully crafted updated to global table and watch networks melt. I think compression makes more sense in controlled environments, but controlled environments with large scale are likely to be exact matches (i.e. bunch of host routes) not LPM anyhow. I'm not optimistic about the technology. -- ++ytti
