Hi all,
We are currently announcing the Corsican Internet subnet (44.190.11.0/24) via a Vultr VPS
($5/mo), which is one of the cheapest and easiest way I know. We have an iBGP (internal)
session with them, and they announce our addresses from their public AS.
We are developing the network on our island. We'd like to have redundant BGP
announcement from two different locations and/or from two different providers. We have
several BGP capable providers.
Questions :
- Does that mean we need to have our own AS number ?
Short answer: yes.
- If so, what's the best way to obtain such an AS
number ? Does ARDC provide public AS numbers ? Or do we have to get one from regular
Internet LIR ?
ARDC do not provide ASNs, you will need to obtain one from a LIR.
- If so, does that mean I won't be able to use
Vultr anymore (because Vultr announces our IPs from their AS, and AFAIK, they do not allow
to announce from our own AS) ?
IIRC Vultr will allow you to announce to them from your own ASN if you have one, otherwise
they issue you with a private ASN, however the announcement has to come from one of their
VMs, so how you would then route the prefix to another provider for announcement could get
interesting.
It’s possible with tunnels I guess, but the traditional way would be to have your own BGP
edge router in a datacenter and hook up feeds from two transit providers. Doing it this
way also gives you the option of peering with multiple other networks, if you’re in a
carrier neutral datacenter.

Thank you in advance.
