Configuring RSTP | The Rapid Spanning Tree Protocol (RSTP) optimizes STP. RSTP allows a newly |
| elected root port or designated port to enter the forwarding state much quicker |
| under certain conditions than in STP. As a result, it takes a shorter time for the |
| network topology to become stable. |
| Although RSTP support rapid network convergence, it has the same drawback as |
| STP does: all bridges within a LAN share the same spanning tree, so redundant |
| links cannot be blocked based on VLANs, and the packets of all VLANs are |
| forwarded along the same spanning tree. |
