I will try and keep this simple. We have 6 sites in our fully routed network.
Site 1 - 4 DCs - 1Gbps connection
Site 2 - 1 DC - 1Gbps connection
Site 3 - 1 DC - 50Mbps connection
Site 4 - 1 DC - 100Mbps connection
Site 5 - 1 DC - 100Mpbs connection
Site 6 - 1 DC - 20Mbps connection
All of these sites were in the same site link and none of the subnets were mapped to sites. I have since then, mapped all of our sites without dcs (These are offices with 1 or 2 people) to the closets DC.
I linked site 1 and 2 with the 1Gbps connection together. I then linked site 3 and 4 to site 1, and , linked site 2 to site 5 and 6.
What I am wondering, is if the circuit @ site 1 goes down, will site 3 and 4 be able to replicate? Same for Site 2. How this is configured now, is it best practice? I have no more than 2 sites in a site link. Should I link site 6 and 5 to site 1 with a higher cost?
Any help will be greatly appreciated! I started looking into this when I noticed how long it was taking password resets to replicate. Just by doing this alone has fixed the problem. I just want to make sure this correctly configured. Please be critical and give me any tips to make this better!
