Active Directory Site topology redesign RRS feed

  • Question

  • I have inherited an active directory containing 10 sites (A-J), each site contains its own Global Catalog and Active Directory Integrated DNS server. Currently, all sites are connected via the defaultipsitelink.  I would like to update this topology by creating site links between Site A and all satellite offices (B-J).  Connection bandwidth ranges from 10Gbps to 5Mbps.  I'd like to create a hub and spoke topology to match our physical network.  So, site connections would look like: A-B, A-C, A-D, A-E, A-F, A-G, A-H, A-I, A-J, varying the cost to correspond with bandwidth.

    SITELINK:COST
    A-B:750
    A-C:250
    A-D:250
    A-E:250
    A-F:100
    A-G:1000
    A-H:250
    A-I:250
    A-J:500


    Should I disable site link bridging?
    If I disable bridging and all DCs in Site A go down, replication happens between sites according to the lowest cost link, correct?  (Site B would never replicate to Site G).
