9.The master node receives the Health message on its secondary port

The master node receives the Health message on its secondary port (port 2). This tells it that all links on the ring are up again.

10.The master node returns the ring to a state of Complete

The master node blocks its secondary port for the data VLAN, unblocks its primary port, transmits a Ring-Up-Flush-FDB message, flushes its FDB, sends a trap, and changes the EPSR state to Complete.

11.The master node receives the Ring-Up-Flush-FDB message on port 2

The master node receives the Ring-Up-Flush-FDB message back on its secondary port, because the packet traversed the whole ring. The master node ignores the message.
