[App_rpt-users] Loop prevention?

I am using app_rpt under Allstar, as I suspect many others are. I know I can connect to one or more nodes. What happens if A <-> B, B <-> C, and A <-> C? Would this cause some sort of loop, or is this handled at the IAX2 protocol level? In particular, I am wondering if it would create any sort of message storm, where the link-level app_rpt messages that are sent over the IAX2 connection would just be sent constantly... --Michael
