If the subnet is the same at both sites ie. 10.1.0.0/16 then you will not be able to route between them. You need to use diffferent subnets at each site if you want to route between sites.

Hi,

Adding to Jon...

As long as you have same subnet at both buildings why do you need routing?
You need to use different ranges at each building.

Please rate the helpfull posts.

If this is a DC changing the IPs is not always straightforward because some applications actually refer to hardcoded IPs instead of a DNS name. They shouldn't but sometimes they are. So it is not a decision to made lightly.

Another possible option is to leave the IPs as they are use NAT to present the IPs as a different IP subnet(s) to the other site.

It's very difficult to say with the limited amount of information you have supplied.

can use nat to solve this problem
