Failure in forwarding VLAN packets due to RSTP
2.6.2 Preparation for configuration
Networking situation
In a big LAN, multiple devices are concatenated for accessing each other among hosts. They
need to be enabled with STP to avoid loop among them, MAC address learning fault, and
broadcast storm and network down caused by quick copy and transmission of data frame. STP
calculation can block one interface in a broken loop and ensure that there is only one path
from data flow to the destination host, which is also the best path.
