Hi we have two servers which are hosted at two different location and we want to load balance the traffic for these two server in Active/ standby mode

details are as below

1)    Server-A IP address is 10.10.2.50/24 and Server-B would be 20.20.20.50/24

2)    Server-A hosted at Location-A datacenter & Server-B hosted at location-B datacenter.

3)    If end  users hit on the IP 10.10.2.20 or URL based on this IP  then  traffic get rerouted to Server-A.

4)    In case  of failover traffic gets rerouted to DR site where Server-B is hosted.


Is it possible to do on router level ?


Thanks in advance.

In case of failover? What does this mean to you? How are those locations connected? What router models you use?

Hi Florin,



Failover : I mean in case server-A goes down then whenever users hits on virtual ip traffic should automatically redirects to Server-B.

And these location are connected by WAN and on Cisco 4503


Please find attached the network diagram.

One option hitting in my mind could be:-


you should use same IP for both servers, if one goes down then u can re-route the traffic, it can be easily managed via any dynamic protocol or static floating route.
