Subject Re: Public CIDR in vpc
Date Mon, 14 Oct 2013 21:05:55 GMT
I'm not necessarily thinking about route advertisement or something
that could be disruptive, if someone brought up a VPC with public
address space it simply wouldn't work outside of the VPC (although
that may be something to consider as well).  I was primarily thinking
about a situation where the admin could assign someone a VPC with say
a /20 of public space (to be further carved into /24 or something on
the VPC networks), and then the admin would point the upstream router
to the VPC router for that /20 (via SDN or whatever means they're
using for the larger orchestration).  It doesn't seem like there'd be
much work to enable this case outside of disabling the check for RFC
1918, and maybe some auditing to ensure any router scripts aren't
expecting private space. Am I wrong?
