multihoming is simple, you get an address block and route it to your upstreams. the policy surrounding that is another debate, possibly for another group this thread is discussing how v4 to v6 migration can operate on a network level Steve On Fri, Jun 29, 2007 at 01:37:23PM +, Christian

Amazink! Some things on NANOG _never_ change. Trawling for trolls I must be. If you want to emulate IPv4 and destroy the DFZ, yes, this is trivial. And you should go ahead and plan that migration. As you well known, one of the core assumptions of IPv6 is that the DFZ policy stay intact,

6to4 and Teredo relays deployment

2007-06-29 Thread JORDI PALET MARTINEZ
Some weeks ago I started to work in documenting how to setup 6to4 and Teredo relays/servers in several platforms for the afripv6-discuss mailing list. There are many 6to4 relays already, but it becomes even more important to have them where the bandwidth is more expensive, because it avoids

Hi Christian, I am not seeing how v4 exhaustion, transition to v6, multihoming in v6 and destruction ov DFZ are correlated. If you took everything on v4 today and migrated it to v6 tomoro the routing table would not grow - actually by my calculation it should shrink (every ASN would only

Hi Steve, Sure... I've never mention 3 STM4... the example said 3 carriers. OK, you may do it with communities, but if you advertise all in just one prefix, even with communities, I find it very difficult to control the trafic when it pass through 2 or more AS (it may be quite easy for the
