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
