Hi All,

I have a scenario where I would like to perform BGP with my current ISP and
am in need of a Internet Edge router; as currently my ASA connects directly
to them.  The IP subnet assignment that I'm using from my provider in my DMZ
will be my provider independent addresses.

My question is....I'll need to put a new subnet between my ASA and my new
Internet router...it can't be a private subnet, because the Outside
interface of the ASA is where my web traffic is coming from.  What are my
options here?...try to subnet the already in use /24 provider independent
subnet in my DMZ and use a /29 as a connector subnet between the ASA Outside
interface and the Internet Edge router?

Thanks

Donald
