實驗拓撲
實驗需求
- 全網依照拓撲圖配置vlan和IP地址
- 總公司：
a) SW3和SW4的互連接口啟用eth-trunk，最大帶寬為2G
b) SW1、SW2、SW3、和SW4運行MSTP，SW1為VLAN10的Root，SW2為VLAN20的Root
c) PC1-PC4需要提供網關冗余，為了提高安全性，需要做認證，並使用BFD動態檢查上行鏈路狀態，實現自動切換
\3. AS100需求：
a) 每台設備都需要配置Loopback接口，地址為X.X.X.X（X為設備編號）
b) AS100底層IGP協議為IS-IS，區域類型為level-2，確保各路由器的loopback接口互通
c) R1與R4建立IBGP鄰居（使用loopback接口）
d) MPLS-VPN需求：
\1. 總公司的PC能訪問分公司1/2的PC，分公司之間不能互訪
\2. R1和SW3、SW4之間運行OSPF協議
\3. R4和R5之間運行BGP協議
\4. R4和R6之間運行OSPF協議
\5. R1和R4建立MP-BGP鄰居
\4. 分公司1需求：
a) SW5為二層交換機，PC5與PC6配置不同VLAN（屬於不同網段），確保兩台PC能互訪
\5. 分公司2需求：
a) PC8與PC7屬於不同VLAN（相同網段），通過VLANIF技術讓兩台PC正常訪問總公司，但是不能互訪
b) 內部IGP運行OSPF協議，為了加快收斂速度，每網段不允許存在DR
