Background:

Here is an example setup.

NAS #1 - NMS (Main)
NAS #2 - NMS (Backup)
NAS #3 - A tenant dedicated hub.

Replication setup

NAS #1 <-> NAS #2 (Bi-directional)
NAS #3 --> NAS #1 (One way)
NAS #3 --> NAS #2 (One way)

Circular loop in the transfer process was involved in this setup.

When 3 or more NASes are involved in the circular type replication, please enable "Relay forwarded alarm events" in all NAS probes.

Without this flag, NAS does not automatically attempt to recognize circularity. The flag allows all NASes to recognize when an alarm has made a circular loop in the transfer process.
