We have an AD forest that covers 60+ sites, which is made up of 24 child domains attached to a root.
Currently our AD site links do not represent our physical network layout. I have been given the job to sort this out. I am having trouble finding any information on the best way of recreating our physical MPLS any-to-any network in AD. The previous person who used to look after Active Directory created site links in a random sort of fashion which was just plain wrong. I am after some advice from anyone with experience in this sort of setup. My plan was to create a new server-less site representing the MPLS network cloud then connect all 60 + sites to the MPLS site. I would then assign replication costs and times to the site links based on the bandwidth of those connections. Once that had all been setup I would then start to remove all the old site links and I should be left with my ideal AD site link design. Would this work? Would the ISTG running on one of the domain controllers in each of the sites calculate the replication cost between different sites by using the MPLS site even though there is not a domain controller in it? I would be grateful for any advice on this matter.
