cisco之VTP
VTP（虛擬局域網中繼協議）：是思科的私有協議，通過VTP協議，可以實現交換機之間互相傳遞消息，從而實現VLAN的同步和統一管理。
VTP示例：
R3:
R3(config)#int f1/1 #trunk模式
R3(config-if)#switchport mode trunk
R3(config)#vtp domain cisco #所有啟用VTP的交換機域名一致
R3(config)#vtp password cisco #VTP密碼一致
R3(config)#vtp mode server #VTP域至少有一臺處於服務器模式，以便於
R3(config)#vtp pruning 創建、修改、刪除VLAN
Pruning switched on
R3(config)#vlan 10 #新建VLAN
R3(config-vlan)#name vlan10
R3(config-vlan)#vlan 20
R3(config-vlan)#name vlan20
R3(config)#int vlan 1 #管理IP
R3(config-if)#ip add 172.16.1.1 255.255.255.0
R3(config-if)#no sh
R3#sh vlan-switch #查看VLAN
