To enable reciprocal replication between two sites
1.In ADSI Edit, expand the Configuration container.
2.Navigate to the Inter-SiteTransports container, and select CN=IP . (You cannot enable reciprocal replication for SMTP links.)
3.Right-click the site link object for the sites for which you want to enable reciprocal replication, and then click Properties .
4.In the Select a property to view box, select options .
5.In the Edit Attribute box, if the Value(s) box shows , type 2 in the Edit Attribute box.
If the Value(s) box already contains a value, you must derive the new value by using a Boolean BITWISE-OR calculation on the old value, as follows: old_value BITWISE-OR 2. For example, if the value in the Value(s) box is 1, calculate 0001 OR 0010 to equal 0011. Type the integer value of the result in the Edit Attribute box; for this example, the value is 3.
6.Click OK .
