Hi Senthil,

To have same ip address in both DC and DR lots of things needs to be taken in consideration as you want load balacning between the application or failover mechanism and what is teh type of traffic which will hit the application from where like internet or MPLS or some other sources.

Check out the below link on active/active DCguideline

Re: Same IP in DC and DR- What to do?

Dear Ganesh,

                    In our Project, DR is used for failover only if anything happens in DC..Simillarly in IDR site, we are going to store some important datas from DC..Same application Servers, Same configuraion and same IP scheme in both DC and DR...In this case what we have to do?

Please See the network diagram.

Tks&Rgds

Hi Senthil.R,

Ok the best way is to have silent DR with DC as active mode,I mean to say have the same ip addressing at DR as well but isolate teh DR network from DC and others.In case if any failure occur enable the link to reach DR with making DC link down.

In this way you can have DR network identical to others.

Hope to help !!
