Your network contains one Active Directory forest named contoso.com. The forest contains two
child domains and six domain controllers. The domain controllers are configured as shown in the
following table.
You need to ensure that all Active Directory changes are replicated to all of the domain controllers in
the forest within 30 minutes.

Set-ADReplicationSiteLink
For each site link object, you can specify a value for the replication period, which determines how often replication occurs over the site link during the time that the schedule allows. For example, if the schedule allows replication between 02:00 hours and 04:00 hours, and the replication period is set for 30 minutes, replication can occur up to four times during the scheduled time.

Good catch rlado and coody scoops, Set-ADReplicationSite would have to be run 3x.
ReplicationFrequencyInMinutes
Species the frequency, in minutes, for which replication will occur where this site link is in use between sites. Active Directory preserves bandwidth between sites by minimizing the frequency of replication and by allowing you to schedule the availability of site links for replication. By default, intersite replication across each site link occurs every 180 minutes (3 hours). You can adjust this frequency to match your specific needs. Be aware that increasing this frequency increases the amount of bandwidth used by replication.
