Regardless of the real answer, > enterprises are not willing to buy into vendor lock. Except there really is no vendor lock anymore. It is possible to automate the entire renumbering process. If there are spots where it is not automated then they should be found and fixed. One of the best ways to get these things fixed would be for the router/firewall/... companies to actually switch between prefixes on a regular (monthly initially) basis. This of course assumes that they are using their own products. Can my firewall be reconfigured just by adding/deleting a prefix? Can my router be reconfigured just by adding/deleting a prefix? Can my ... Similarly multi-home some sites out of PA space and regularly break connectivity on to one or more providors. Nothing like doing to work out the bugs is the system.
