CCNP - RSTP (Rapid SpanningTree Protocol)
Lab 50 Rapid SpanningTree Protocol
Pada STP default jika terjadi kendala atau kerusakan pada jaringan utama maka jalur data akan dipindahkan melalui jalur alternatif, tetap ini membutukan waktu lebih dari 30 detik untuk bisa connect. dengan metode RSTP, waktu tunggu tersebut akan dipercepat hingga kurang dari 1 detik agar koneksi pulih kembali.

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
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
Kita cek di SW-1
