Great! Now we have to collect routing policies from thousands of small LIRs while still have to deal with thousands of small prefixes.
This is what i meant: if we "renumber" the old swamp space not only in RIPE Region, we have a cleaner routing table. many of the old swamp space "owners" are single homed, which would clean up a lot in the routing table if they are forced to use PA space from the respective provider.
And if the major ISPs stop listening to the more specfic routes then even using the address from PI space won't work (unless you are big enough).
Right, see my above comment.
All these solutions kind of imply that if you can't have /20 prefix then you can't be multi-homed. What happen if a customer want to have an OC-48 multi-homed link but only use prefix < /20 (that happens to the Internet Exchange people a lot ) ?
There should be also made some "golden networks" for the exchanges and "important" services, like DNS. This, correctly implemented together with the vendors, could make live easier: - route flap dampening works together seamless with the correct networks in "default" configurations. - more stability - less routes in routing table - clear "border" of address space together with registry borders. But again, these are only ideas from network operators. --jan -- Jan-Ahrent Czmok http://www.lambda-solutions.de Technical Advisor ISP Hofdcker Str. 14, 65207 Wiesbaden Tel. +49-(0)-174-3074404
