拓撲設計：
實驗要求：
內網ip位址172.16.00/16 合理分配
sw1/2之間互為備份
vrrp/stp/vlan/trunk均使用
所有pc通過dhcp獲取ip位址
子網劃分
172.16.1.0/24 vlan1
172.16.2.0/24 vlan2
ethtruck的配置
[sw1]inte***ce eth-trunk 0
[sw1-eth-trunk0]int g0/0/2
[sw1-gigabitethernet0/0/2]eth-trunk 0
[sw2]inte***ce eth-trunk 0
[sw2-gigabitethernet0/0/2]eth-trunk
[sw2-gigabitethernet0/0/3]eth-trunk 0
truck
給三層交換機eth-trunk 0 g0/0/4 g0/0/5設定truck幹道
二層ethernet0/0/1和ethernet0/0/2設定truck幹道
ethernet0/0/3和ethernet0/0/4用access
stp協議
給每層交換機設定stp，三層交換機1vlan1為主根，vlan2為備份 三層交換機2vlan2為主根，vlan1為備份 ，以sw1為例

一 概要 這篇部落格，準備用乙個小demo來介紹應該實現三層架構。三層架構只是分層的一種經典形式，到底分幾層，要依具體情況而定，考慮到系統的複雜程度，和後期的可維護性，完全可以分四層，五層，甚至六層，七層。二 demo 1 實現語言 vb.net 2 需求 學校機房收費系統 中的乙個功能 操作員為學...
