Konfigurasi PVST+

1. Buka Cisco Packet Tracer

2. Buat skema jaringan seperti di gambar

3. Buatlah VLAN 10, 20, 30, 40, 50, 60, 70, 80 dan 99 pada semua switch.

S2(config-vlan)#vlan 60
S2(config-vlan)#vlan 70
S2(config-vlan)#vlan 80
S2(config-vlan)#vlan 99

S3(config-vlan)#vlan 60
S3(config-vlan)#vlan 70
S3(config-vlan)#vlan 80
S3(config-vlan)#vlan 99
S3(config-vlan)#exit

4. Mengaktifkan mode access pada semua switch dan mendaftarkan vlan - vlan yang telah ditentukan

S1(config)#interface f0/6
S1(config-if)#switchport mode access 
S1(config-if)#switchport access vlan 30
S1(config-if)#no shutdown
S1(config-if)#exit

S2(config)#interface f0/18
S2(config-if)#switchport mode access 
S2(config-if)#switchport access vlan 20
S2(config-if)#no shutdown
S2(config-if)#exit

S3(config)#interface f0/11
S3(config-if)#switchport mode access 
S3(config-if)#switchport access vlan 10
S3(config-if)#no shutdown
S3(config-if)#exit

5. Mengaktifkan mode trunk native VLAN 99 pada semua switch

S1(config)#interface range f0/1-4
S1(config-if-range)#switchport mode trunk 
S1(config-if-range)#switchport trunk native vlan 99
S1(config-if-range)#exit

S2(config)#interface range f0/1-4
S2(config-if-range)#switchport mode trunk 
S2(config-if-range)#switchport trunk native vlan 99
S2(config-if-range)#exit

S3(config)#interface range f0/1-4
S3(config-if-range)#switchport mode trunk 
S3(config-if-range)#switchport trunk native vlan 99
S3(config-if-range)#exit

6. Berikanlah ip address terhadap VLAN 99 pada semua switch

S1(config)#interface vlan 99
S1(config-if)#ip address 172.31.99.1 255.255.255.0
S1(config-if)#exit

S2(config)#interface vlan 99
S2(config-if)#ip address 172.31.99.2 255.255.255.0
S2(config-if)#exit

S3(config)#interface vlan 99
S3(config-if)#ip address 172.31.99.3 255.255.255.0
S3(config-if)#exit

7. Konfigurasi STP dan PVST+ Load Balancing

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

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

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

8. Konfigurasi Portfast dan BPDU Guard

S1(config)#interface f0/6
S1(config-if)#spanning-tree portfast 
S1(config-if)#spanning-tree bpduguard enable

S2(config)#interface f0/18
S2(config-if)#spanning-tree portfast 
S2(config-if)#spanning-tree bpduguard enable

S3(config)#interface f0/11
S3(config-if)#spanning-tree portfast 
S3(config-if)#spanning-tree bpduguard enable
