RSTP (Rapid Spanning Tree Protocol)

 

 Konfigurasikan switch dmana 1 vlan akan menggunakan 1 STP Instance

 SW1 menjadi Root untuk vlan 10, 20, 30

 SW2 menjadi Root untuk Vlan 40, 50, 60 

KONFIG

SW-1

SW1(config)#no spanning-tree mst configuration

SW1(config)#spanning-tree mode rapid-pvst

SW1(config)#spanning-tree vlan 10,20,30 root primary

SW1(config)#spanning-tree vlan 40,50,60 root secondary

SW-2

SW2(config)#no spanning-tree mst configuration

SW2(config)#spanning-tree mode rapid-pvst

SW2(config)#spanning-tree vlan 10,20,30 root secondary

SW2(config)#spanning-tree vlan 40,50,60 root primary

Verifikasi dan Pastikan SW1 menjadi root bridge untuk vlan 10, 20 dan 30
