Trusted forest with DC shared same AD site and same subnet

Hello All,

I have a question about a specific AD configuration.

We have a Forest thrust between 2 Forest (A and B).

We want to add new DC from forest A in Datacenter of forest B, in the same subnet where Forest B DC's are already installed

So we will use the same subnet and AD site name for DC from different forest.

At first, there should not be any problems, but i just want to be sure.

Thanks,
