Debugging
The Health message from the previous step reaches the master node and shows it that all
links in the ring are now up. The master node sends a Ring-Up-Flush-FDB message. When it
receives the message, the transit node unblocks port 1 for vlan2, flushes its FDB, sends a
trap, and changes the state to Link-Up.
This is the packet shown in step
of the master node debug output.
6. Transit node receives a Ring-Up-Flush-FDB message.
