Hi all,
I like to a post a design question and hope someone in group would be
able to shed some light on this.
The scenario:
Customer A has a production and a WARM DR site. There is a back-end link
btw production and WARM DR site used for back-end server replication and
etc.That explain why the internal LAN address cannot be same on this two
sites. Next, registered IP address for the internet servers must be same,
otherwise they'll have problem with domain-names. This simply means both
production and warm DR site will use identical registered IP address
allocated by Service provider. Under normal operating condition, all traffic
routed to the production site. In the event of disaster or during monthly
live testing, some of the application traffic (i.e. web, email) must be
routed the DR site while maintaining other application to the production
site.
How to achieve this?
Thank you,
Mohan
