RSTP Configuration Example

RSTP Configuration Example

RSTP Configuration on Cisco Packet Tracer

As you know, STP (Spanning Tree Protocol) is the key protocol of Switching world. With STP, link redundancy is provided and switching loops are avoided.

STP has different versions. One of the STP version is RSTP (Rapid Spanning Tree Protocol). Like it name, RSTP (Rapid Spanning Tree Protocol) is the fastest converged version of STP.

In this example, we will configure RSTP (Rapid Spanning Tree Protocol) with Packet Tracer.

You can DOWNLOAD the Cisco Packet Tracer example with .pkt format At the End of This Lesson.

For our RSTP (Rapid Spanning Tree Protocol) example, we will use the below switching topology.

RSTP Configuration with Packet Tracer
 

RSTP Configuration Topology
STP (Spanning Tree Protocol) has four states. These STP states are; Blocking, Listenning, Learning and Forwarding. With RSTP (Rapid Spanning Tree Protocol), the Spanning Tree state Blocking and Listenning are bypassed. The RSTP states that starting with discarded, go through the learning and forwarding.

In STP (Spanning Tree Protocol), Blocking State is 20 seconds, Listenning State is 15 seconds and Learning State is 15 seconds. So, for STP, going through forwarding states needs 50 seconds. This total time is 15 seconds in RSTP (Rapid Spanning Tree Protocol). Because RSTP, bypasses the Blocking and Listenning states.

RSTP Confgiuration

Let’s start to configure RSTP (Rapid Spanning Tree Protocol) on Cisco Packet Tracer.

Switch0(config)# spanning-tree mode ?
pvst Per-Vlan spanning tree mode
rapid-pvst Per-Vlan rapid spanning tree mode

Switch0 (config)# spanning-tree mode rapid-pvst 
Switch0 (config)# end 
Switch0 # copy running-config startup-config 
Switch1 (config)# spanning-tree mode rapid-pvst 
Switch1 (config)# end 
Switch1 # copy running-config startup-config
