RSTP Insights | Sumble

What is RSTP?

Rapid Spanning Tree Protocol (RSTP), defined in IEEE 802.1w, is a network protocol that enhances the original Spanning Tree Protocol (STP) by providing faster convergence times. It is used in Ethernet networks to prevent loops and ensure a loop-free logical topology, making it more resilient and efficient than STP.

What other technologies are related to RSTP?

RSTP Competitor Technologies

MSTP

Multiple Spanning Tree Protocol is an extension of RSTP that allows for multiple spanning trees, providing better load balancing and redundancy. It competes with RSTP by offering more advanced features.

STP

Spanning Tree Protocol is the predecessor to RSTP. While RSTP is designed to be backward compatible, it's a newer and improved version aiming to replace STP, making STP a competitor.

VSTP

VSTP, or VLAN Spanning Tree Protocol, is a Cisco proprietary protocol that runs a separate instance of STP for each VLAN. RSTP is generally preferred over VSTP when available, but represents similar functionality.

PVST+

PVST+ (Per-VLAN Spanning Tree Plus) is a Cisco enhancement to PVST that supports RSTP. While it can interoperate with RSTP, it also represents similar functionality and can be seen as a competitor.

RSTP Complementary Technologies

802.1q/p VLAN

802.1q VLAN tagging allows for the creation of VLANs, which can be used to segment a network and apply RSTP on a per-VLAN basis. This enhances the network design and works in tandem with RSTP.

LACP

Link Aggregation Control Protocol is used to bundle multiple physical links into a single logical link. It can be used in conjunction with RSTP to increase bandwidth and provide redundancy at the link level.
