Two-way trust for adding trusted master server for Targeted Auto Image Replication
With Targeted Auto Image Replication, when establishing trust between the source and the remote target server, you need to establish trust in both the domains.
In the source master server, add the target master server as a trusted server.
In the target master server, add the source master server as a trusted server.
More secure mechanism would use certificates to establish trust, wherein:
You need to validate SHA1 fingerprint of root certificate.
You can use authorization token to establish trust.
