Are there any best practices or guidelines surrounding whether or not one s=
hould use the same or unique AS numbers when advertising via BGP from 2 or =
more physically separate locations? Each location would be advertising at =
least their own unique /24.
My specific scenario is that we are moving our QA Lab to a datacenter that =
we will multi-home with two providers via BGP. We also plan to multi-home =
our corporate office with two providers (not likely to be the same provider=
s) also via BGP. We currently have an AS that is in use for our multi-home=
d production data center. In the interest of keeping production totally se=
gregated from QA/corp I would prefer to not use our production datacenter A=
S for our QA Lab or corporate network, but I've had trouble finding any tec=
hnical reason not to use it. ARIN is asking for a detailed technical expla=
nation to justify my request.
Thanks in advance,
