STP(spanningTreeProtocol,生成樹)就是把一個環形的結構改變成一個樹形的結構，STP協議就是用來將物理上存在環路的網路，通過一種演算法，在邏輯上，阻塞一些埠，來生成一個邏輯結構。

HSRP（hoststandbyroutingprotocol，熱備路由協議）是思科私有的一種技術，它確保了當地邊緣裝置或接入裝置出現故障時，使用者通訊能迅速並透明地恢復，以此為ip網路提供冗餘性。

VTP是一種資訊協議，它使用第二層幀，在交換機之間傳遞VLAN資訊，被稱為VTP通告。

EIGRP（EnhancedInteriorGatewayRoutingProtocol）增強內部網管關由線路協議，

R4-5配置與R3大致相同，只需要更改一下埠號和接受的VLAN即可。

通過命令“showstandbybrief”檢視R1和R2成hsrp，可以看到

通過命令“showspanning-treebrief”檢視到R1，R2，R3的生成樹，可以看到R2的f1/11被阻塞了埠

通過命令”showvtpstatus和showVLAN-swiport”檢視R3的vtp管理情況。

從頂部pc1（ip:20.0.0.2）ping通底部pc2(ip:192.168.10.100)
