I have a top level domain with several child domains spread across 6 geographic regions. I have a mixture of 2003 and 2008 DCs.
I want to implement a full mesh replication topology. Each site is connected by an MPLS link into a the cloud and IPSEC tunnels are created between sites.
Currently my replication topology is hub and spoke, but I'd like to change this to full mesh.
1. How can I best achieve this? Create a single IP site link and dump all my sites in there or create a seperate site link for each connection (15 links in all)? I remember watching an AD vid saying you shouldn't have more than 3 sites in any one link, but I can't find it now.
2. Currently the forest PDC isn't not the authorative time source for the forest, should this be changed?
3. I have a GC in each AD site, when using 2003\2008 DCs in a forest-child domain model, is it worth adding more GCs?
Thanks
