Hi all, I've a single domain with 10 sites. All physical sites are connected to each other in a full mesh network topology. Not all the physical connection has the same bandwidth. I've to design a good replication topology so: Have I to create a site link for each possible connection? i.e. 90 site links? Once I've created sites links, NTDS Settings -> connections are authomatically created?

hello, I suggest you to read these link to get more details about design active directory topology: How Active Directory Replication Topology Works Designing the Site TopologyBest Regards

Hello, which speed/bandwidth are the connections that you define as low? Whenever possible the KCC should do the links without manual changes. Keep in mind that once done manual the KCC is out until you reactivate it. http://blogs.technet.com/b/markmoro/archive/2011/08/05/you-are-not-smarter-than-the-kcc.aspx Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hello Meinolf, thank you for your reply. I've said that all 10 sites are connected to each other. Each site as a single internet connection (single physical line). All internet connections fall to a VPN concentrator mantained by our ISP. Each site has a certain guaranteed bandwidth, the slowest as a 4Mbit/sec the fastest 20MBit/sec. My main question is: "have I to create 90 sites links?" and let KCC calculate the connection objects?
