How do you do this in the IPv6 world, where I get a single /32? Will others accept announcements of two /33s to better handle things like this?
Oooooooooobviously I was not thinking clearly, since I was only considering v4. =) But you do what you can. Some people have only a single v4 prefixes as well. If you can't use more than one prefix, then don't. Other good suggestions were things like ensuring the default exit point for each NS was a different vector. If you have only one exit point, that is not possible. But it does not mean the suggestion is bad. -- TTFN, patrick
