It is
mandatory. But like IPv4 addresses, they are a limited resource, and you need to have
connections to multiple backbone providers to even apply for one. IOW, you need to be in
the business. Nearly all of us here will use the Public ASN of our provider.
That's what I did, because I have no need to peer with anyone. My
provider does all of that. All I had to do was to get the LOA (then
from Brian) to them and possibly their upstream (there wa san extra
little step required in the paperwork from memory), and once the
paperwork was sorted, everything started working. :)
That's what I did with Vultr. That's also what I'm planning to do with
my new business operator. With a single BGP operator, there's no need to
have my own public ASN.
But how could I manage redundancy / fault tolerance between two BGP
operators ?
For incoming traffic, there's no problem, I can handle any incoming
packet whatever the provider.
But how could I handle outgoing traffic ? F/ex, my current Vultr VPS is
hosted in Paris, and I'm tunneling from Corsica to Paris. Last week,
they had a network problem, and the BGP routing was down. All outbound
packets sent from my local router to the Vultr BGP VPS were dropped.
Locally, I do not have any easy way to see if Vultr network is working
or not, so that I could redirect outbound traffic to my 2nd provider.
For now, I do not have any idea about how to handle outbound redundancy.
Having a public ASN, and a local BGP router which peers with the two
providers, may be a clue. Am I wrong ?
