I'm confused. Assuming that the users are separated from their servers by at least one router hop (otherwise if the servers failed, so would the users, so what's the use of the DR?), then why can't you just assign the same IP addresses to the servers at the DR site? If the production servers are up, then the users would get routed to those servers. If the servers or server site fails, then the users would get routed to the DR site, with the backup servers that have the same IP addresses. I fail to see the issue.

Just wanted to know the various solutions can be deployed for such a kindof requirement? ------------------ | |------------------Router C ( Site B,DR Site which is | ISP | in Standby , should --------------------- site A fails) | | | | | | | | ------ ----------- Router A Router B (Site A where A adn B are in VRRP) 1. Active servers behind Router A 2. Router B would kick-in if Router A fails. 3. Incase the site A fails,the traffic should be automatically diverted to Router C (Site B). 4. Site A will be replicated to Site B using a link between Site A and B. 5. Site A and site B has two different IP addressing schemes. 6. Instead of a single ISP, what would be the solution if Router C was conencted to a diffrent ISP? The users (outside to Site A and B) will be accessing site A purely using IP addresses (no DNS). what would be the solution at ISP level to acheive the above reqmt? If the applications were accessed using "names" GSLB would ahve been the solution.
