Re: ISP failures and site multihoming [Re: Enforcing unreachability of site local addresses]
....which explains a lot of bad stuff being deployed, but that is
In a perfect world I'm sure I'd agree with you. In real life however,
the fact of the matter is that customers want multihoming, and it
doesn't matter to the customers if that is a problematic approach that
doesn't scale for the SPs. Doesn't even matter if it's technically the
best solution for THEM, customers are not known for picking the best
solutions, nor listening to their providers suggestions for better
half the time. And, the simple fact of the market economy is that what
the customers want, the providers are going to sell.
Making the IP backbones more resilient costs money. You get that money
from your customers. You get the customers by selling them what they
asking for. What they are asking for is multihoming. If they can't
multihome with IPv6, well, then they won't use IPv6 until they can. If
the customers don't want to use IPv6, the providers won't spend the
money to support it.
...and this is yet another rehash of a discussion that has already been
had so many times by so many people that I'm sure we can just copy &
paste from here on out.
The fact of the matter is, whether it's the best approach or not, we
need a solution for customers to multihome. So let's bring our
back to that, shall we?
I have a suggestion....:)
