One question - which percent of routing table of any particular router isREALLY used, say, during 1 week?I have a strong impression, that answer wil not be more than 20% even inbiggerst backbones, andwill be (more likely) below 1% in the rest of the world. Which makes a higespace for optimization.
As of the last time that I looked at it (admittedly quite awhile ago), something like 80% of the forwarding table had at least one hit per minute. This may well have changed given the number of traffic engineering prefixes that are circulating.
