I'm not arguing about that. All equipment will have troubles in case of routing table explosions. It's my point too.

I don't expect any huge explosion. Reasons was described already in the list. Growth will copy current IPv4 curve... ----------------- Both "sides" doesn't have arguments and reasons, just predictions. PI in IPv4 was a long developed decision, with a lot of restrictions from the beginning, several tuning across its life. So IPv6 PIs will not have the same curve definitely. You have ignored all other my arguments. \\\\\\\\\\\\\\\\\\\\\\\\\\\\ On 05/04/2011 11:10 AM, poty@iiat.ru wrote:

Even at 200Mbit|s with 2 upstreams it is almost impossible to deal with full table.

With proper hardware not really. It's not a problem handle 10Gbps interface on PC these days. And I know about real deployment, where PC is used for routing >8Gbps of traffic. ------------------------- To HAVE the interface doesn't mean to USE it fully. Routing 8Gbps on a PC is unrealistic definitely, even in theory. Many people (try to) pass the desirable for reality. You can certainly incorporate some hardware port accelerators in a PC, additional interfaces, make a cluster... But it seems it would be not cheap at first and claim a competence which small ISPs can't afford at second. It is not a cheap PC with common OS we are speaking about. /////////////////////////////////

We all know the "rule" for IPv4 about not routing longer than /24. I got this problem with some of our PI customers and have learnt, that the money here not always help. So, the filtering is not imaginary thing. Then the deaggregation would be limited (in spite of unlimited PIs).

Minimum PI assignment in IPv6 is /48 - see RIPE 512. Also assigned anycasts in IPv6 are /48 - i expect, that /48 for IPv6 becames similar well-know minimum rule as /24 in IPv4 world. There're legal operational /48 assignments these days - for anycasted TLD-DNS, for example. And /48 can be assigned from /32 PA easily, there's lot of space available. And then easily announced into the BGP and almost nobody will filter it (see current IPv6 table)... ------------------- If it is so easy - use it! Why then you should apply for PI? In case of problems RIPE (for example) would speak with a single LIR, not with thousands of widespread customers. Regards, Vladislav
