[isp-bgp] Multi-site BGP

[Rich Pulver <pulverr@...]

Hello all. I have a question regarding BGP for Disaster Recovery. Does
anyone use BGP currently for fail over to a DR site? If so, is it as simple
as advertising my networks through providers in both locations and
configuring the primary site as the preferred until that site goes away? (Or
am I missing the fact that I won't be able to direct inbound traffic to such
a degree?)

This is what I have

site1 - NY - Primary - 2 x T3 - 3 Class C from 1 provider - ASN with ARIN 

site2 - CA - DR - 2 X T3

I am already running BGP with two upstreams in NY. Can I just advertise my
routes and ASN in CA so all traffic will be redirected there if anything
happens in NY? Are there any ramifications to this type of setup? Any input
would be greatly appreciated. Thanks.
