Explanation
An RSTP topology contains ports that have specific roles: The root port is responsible for forwarding data to the root bridge. The alternate port is a standby port for the root port. When a root port goes down, the alternate port becomes the active root port. The designated port forwards data to the downstream network segment or device. The backup port is a backup port for the designated port. When a designated port goes down, the backup port becomes the active designated port and starts forwarding data.
