3.3.2.2 Packet Tracer – Configuring Rapid PVST 

Part 1: Configure VLANs

 

Step 1: Enable the user ports on S2 in access mode.

S2(config)# interface range f0/6,f0/11,f0/18

S2(config-if-range)# switchport mode access

S2(config-fi-range)# no shutdown

 

Step 2: Create VLANs.

S1(config)# vlan 10

S1(config-vlan)# vlan 20

S1(config-vlan)# vlan 30

S1(config-vlan)# vlan 40

S1(config-vlan)# vlan 50

S1(config-vlan)# vlan 60

S1(config-vlan)# vlan 70

S1(config-vlan)# vlan 80

S1(config-vlan)# vlan 99

 

S2(config)# vlan 10

S2(config-vlan)# vlan 20

S2(config-vlan)# vlan 30

S2(config-vlan)# vlan 40

S2(config-vlan)# vlan 50

S2(config-vlan)# vlan 60

S2(config-vlan)# vlan 70

S2(config-vlan)# vlan 80

S2(config-vlan)# vlan 99

 

S3(config)# vlan 10

S3(config-vlan)# vlan 20

S3(config-vlan)# vlan 30

S3(config-vlan)# vlan 40

S3(config-vlan)# vlan 50

S3(config-vlan)# vlan 60

S3(config-vlan)# vlan 70

S3(config-vlan)# vlan 80

S3(config-vlan)# vlan 99

 

Step 3: Assign VLANs to switch ports.

S2(config)# interface f0/6

S2(config-if)# switchport access vlan 30

S2(config-if)# interface f0/11

S2(config-if)# switchport access vlan 10

S2(config-if)# interface f0/18

S2(config-if)# switchport access vlan 20

 

Step 5: Assign the trunks to native VLAN 99

S1(config)# interface range f0/1-4

S1(config-if-range)# switchport mode trunk

S1(config-if-range)# switchport trunk native vlan 99

 

S2(config)# interface range f0/1-4

S2(config-if-range)# switchport mode trunk

S2(config-if-range)# switchport trunk native vlan 99

 

S3(config)# interface range f0/1-4

S3(config-if-range)# switchport mode trunk

S3(config-if-range)# switchport trunk native vlan 99

 

Step 6: Configure the management interface on all three switches with an address.

 

S1(config)# interface vlan99

S1(config-if)# ip address 172.17.99.11 255.255.255.0

 

S2(config)# interface vlan99

S2(config-if)# ip address 172.17.99.12 255.255.255.0

 

S3(config)# interface vlan99

S3(config-if)# ip address 172.17.99.13 255.255.255.0

 

 

Part 2: Configure Rapid Spanning Tree PVST+ Load Balancing

 

Step 1: Configure STP mode.

S1(config)# spanning-tree mode rapid-pvst

S2(config)# spanning-tree mode rapid-pvst

S3(config)# spanning-tree mode rapid-pvst

 

Step 2: Configure Rapid Spanning Tree PVST+ load balancing.

S1(config)# spanning-tree vlan 1,10,30,50,70 root primary

S2(config)# spanning-tree vlan 1,10,20,30,40,50,60,70,80,99 root secondary

S3(config)# spanning-tree vlan 20,40,60,80,99 root primary

 

Part 3: Configure PortFast and BPDU Guard

 

Step 1: Configuring PortFast on S2.

S2(config)# interface range f0/6 , f0/11 , f0/18

S2(config-if-range)# spanning-tree portfast

 

Step 2: Configuring BPDU Guard on S2.

S2(config)# interface range f0/6 , f0/11 , f0/18

S2(config-if-range)# spanning-tree bpduguard enable

 

Step 3: Verify your configuration.
