实验拓扑

实验需求

全网依照拓扑图配置vlan和IP地址总公司：

a) SW3和SW4的互连接口启用eth-trunk，最大带宽为2G

b) SW1、SW2、SW3、和SW4运行MSTP，SW1为VLAN10的Root，SW2为VLAN20的Root

c) PC1-PC4需要提供网关冗余，为了提高安全性，需要做认证，并使用BFD动态检查上行链路状态，实现自动切换

\3. AS100需求：

a) 每台设备都需要配置Loopback接口，地址为X.X.X.X（X为设备编号）

b) AS100底层IGP协议为IS-IS，区域类型为level-2，确保各路由器的loopback接口互通

c) R1与R4建立IBGP邻居（使用loopback接口）

d) MPLS-VPN需求：

\1. 总公司的PC能访问分公司1/2的PC，分公司之间不能互访

\2. R1和SW3、SW4之间运行OSPF协议

\3. R4和R5之间运行BGP协议

\4. R4和R6之间运行OSPF协议

\5. R1和R4建立MP-BGP邻居

\4. 分公司1需求：

a) SW5为二层交换机，PC5与PC6配置不同VLAN（属于不同网段），确保两台PC能互访

\5. 分公司2需求：

a) PC8与PC7属于不同VLAN（相同网段），通过VLANIF技术让两台PC正常访问总公司，但是不能互访

b) 内部IGP运行OSPF协议，为了加快收敛速度，每网段不允许存在DR
