I'd want to ask the question why do you (or the customer) want to do this. There may be no problem advertising the /24 today but there may be in the future. Why not use address space from your provider? We all have a responsibility to try to do the 'right thing' with address space. Just because you can do something, doesn't mean you should.
What's the problem here? Aggregating address space was important back when memory was expensive, router manufacturers believed that 16 MB was more than anyone could ever use, and the CPUs were mainly 68000s and derivatives. There are only 14 million or so possible /24 blocks. Even if every possible /24 was advertised (and they aren't), the routing table and all its related hangers on should fit inside a gig or so. I can buy a PC with enough horsepower and memory to run the routing for the worst cases we're likely to see on the Internet for around NZ$3000. Really, this "gotta have a small prefix" thing is silly. it prevents outfits that have small address space needs from peering with multiple providers without massively wasting address space. Sure, if you're singly connected, you don't need provider independant address space. But applying thinking based on 1980s routing technology to address space management is just dumb. -- don - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
