Active directory sites and services

Hi

Any one help me how to domain replication.

1. i have created separate forest and installed in active directory 2008 and the ip address 192.168.1.210

2. Again i have created one more separate forest and installed active directory 2008 and the ip address 192.168.1.220

Both are ping and domain trust is happening .

But in this i want to create domain replication to this two separate forest domain .

in 192.168.1.210 site and services only one server is showing in that and please tell me how to import 192.168.1.220 server in the sites and services console.
