What is RSTP (Rapid Spanning Tree Protocol)

Rapid Spanning Tree Protocol (RSTP) is a computer networking protocol that is used to prevent loops in a network and to ensure a loop-free topology. RSTP is an improvement over Spanning Tree Protocol (STP) that provides faster convergence and improved network stability.


RSTP works by building a spanning tree that represents the network and shows only one active path between any two devices. The spanning tree is used to block redundant links and prevent loops in the network. RSTP introduces new port states and a new BPDU (Bridge Protocol Data Unit) format to achieve faster convergence. RSTP also has a more efficient algorithm for determining the active and blocked paths in the network.

In the event of a network change, such as the failure of a link or the addition of a new device, RSTP can converge in just a few seconds, compared to 30-50 seconds for STP. This makes RSTP well-suited for large, rapidly changing networks, where network topology changes frequently.

RSTP is widely used in Ethernet networks and is specified in the IEEE 802.1W standard. It is supported by most networking equipment and is commonly used in enterprise networks, data centers, and service provider networks.

How to configure STP on a switch

Spanning Tree Protocol (STP) is a networking protocol used to prevent loops and ensure a loop-free topology in a network. STP is typically configured on network switches to prevent the formation of loops and to ensure the stability of the network. Here are the steps to configure STP on a switch: Access the switch's command line interface (CLI) using a terminal program like Telnet or SSH. Configure the switch as the root bridge by setting its bridge ID to a lower value than any other switch in the network. The bridge ID is typically a combination of the switch's MAC address and a priority value. Configure the switch's ports. Each port should be configured as either a root port, designated port, or blocked port. The root port is the port that is closest to the root bridge and is used to forward traffic to the root bridge. The designated port is the port that is closest to a downstream switch and is used to forward traffic to that switch. The blocked port is a port that is not
