网络拓扑如图所示：
网络地址规划：vlan 2 10.147.140.0/26
vlan 3 10.147.140.64/26 用于行政楼段；
vlan 4 10.147.140.128/26
vlan 5 10.147.140.192/26 用于中控楼段；
vlan 10 10.147.141.0/30
vlan 11 10.147.141.4/30
vlan 12 10.147.141.8/30
vlan 13 10.147.141.12/30 用于核心交换机到路由器互联网段。
网络协议使用：接入层到汇聚层使用MSTP，各设置两个实例，分别以其中某台汇聚交换机实例为区域 根；
汇聚层到核心层使用VRRP，使用4个虚拟组，分别以某台核心交换机为master，另一台为 backup；
核心层至广域网使用OSPF，设置成等价路径。
