This wouldn't be done by BGP . You would have to do this with a global load
balancer and DNS possibly using BGP metrics as a closest path to the end
users DNS. Using say Distributed Director you would set it up as
authoritative for that domain you could have it set up that if his site went
down the servers at your site would then pick up the load.

Subject: BGP Design Question
A customer runs BGP advertising a class C network to two service
providers for web site redundancy.
I run BGP as well advertising my class C to two network providers. What
we would like to do is duplicate his web server and database servers and
co-locate them at my office. We would connect our offices through some
T1's for database replication, etc. If by chance his connections go down
I would like for his domain to reroute to me.
I don't know if I can do this, I am having difficulty thinking outside
of the box on this one. Considering lack of real world BGP experience :)
I am thinking of creating peers between his AS and Mine through the T1's
connecting our networks. If his connections go down my AS will advertise
and alternate path to his web servers. Is this correct thinking?
Thanks for any help.
