It would be pretty hard to create 2^32 routes, given that IPv4 only has 32-bit addresses. :-) Also, if you time it I suspect you'll find that it would take a geological lifetime on a fast machine to add that many routes. I think it makes more sense to increase the size of the reference count as discussed, rather than adding checks that add more complexity and overhead. John --- John Polstra jdp@polstra.com John D.
