6.1.1.2.2.3.3 Site Link Object
For a DC in one site to replicate directly with a DC in a different site, a siteLink object (or a series of siteLink objects) must connect the two sites specified. A siteLink object identifies the transport (wire protocol) to be used for replication between the sites. If the transport is IP, the siteLink object is a child of the IP Transport container. If the transport is SMTP, the siteLink object is a child of the SMTP Transport container. Any single siteLink object may encompass two or more sites. If a siteLink object contains two sites, then those two sites are considered to be directly connected. If a siteLink object contains more than two sites, then all of the sites listed in the siteLink are considered to be connected in a mesh of point-to-point links.
parent: Either IP Transport container or SMTP Transport container.
systemFlags: FLAG_CONFIG_ALLOW_RENAME
cost: An administrator-defined cost value associated with that replication path.
siteList: Contains the DSName of the site objects for the sites that are connected using this site link.
replInterval: An interval that determines how frequently replication occurs over this site link during the times when the schedule allows replication.
schedule: Replication schedule of type SCHEDULE that specifies the time intervals when replication is permitted between the two sites.
options: A set of the following bit flags presented in big-endian byte order.

UN (NTDSSITELINK_OPT_USE_NOTIFY, 0x00000001): If present, enables replication notifications (see Updates, section 3.1.1.5) between DCs in different sites in the siteList.
-
TS (NTDSSITELINK_OPT_TWOWAY_SYNC, 0x00000002): If present, forces a replication cycle in the opposite direction at the end of a replication cycle between DCs in different sites in the siteList.
-
DC (NTDSSITELINK_OPT_DISABLE_COMPRESSION, 0x00000004): If present, disables compression of IDL_DRSGetNCChanges response messages sent between DCs in different sites in the siteList.
