AD Site Topology Design [Inter Site Link Metric, Cost value, replication schedule]
Posted on 2014-02-13
I'm in charge of auditing our AD Site topology (number of Site link, cost value, Replication schedule and Site link Bridge)
The thing is that i don't know what cost i should advise. I know the lower the cost value the more prioritize it will be)
Our environment is one Forest
Child domain is region domain (4 domains => One domain per region)
We have on our topology
1- Strategic sites where one of each site (Region big site) contain more than 10 RWDCs; and should replicate with one another. Good WAN => what site link Cost Value i should advise ?
2- Hub Site (Region sites smaller than big sites) contain 2 RWDCs that should replicate with strategic sites Good WAN => what site link Cost Value i should advise ?
3- Remote site (Region sites smaller than Hub sites) contain 1 RODC or RWDC that should replicate with Hub sites. Poor Network WAN => what site link Cost Value i should advise ?
NB: I know the numbers don't really matter, but i want is a cost value strategy that make sens, so that users from smaller Remote site don't authenticate on DCs in strategic site.
I need advise or related Document i can rely on.
