7.7.2 Example for Configuring Basic RSTP Functions
This example shows how to configure basic RSTP functions.
Networking Requirements
On a complex network, loops are inevitable. With the requirement for network redundancy
backup, network designers tend to deploy multiple physical links between two devices, one of
which is the master and the others are the backup. Loops are likely or bound to occur in such a
situation.
Loops will cause broadcast storms, thereby exhausting network resources and paralyzing the
network. Loops also cause flapping of MAC address tables and damages MAC address entries.
