实验拓扑图：

交换的最后一步配IP,配置路由第一步是配IP。

实验思路：

第一步写聚合： eth-trunk

        SW1

                [sw1]int Eth-Trunk 0  
                [sw1-Eth-Trunk0]trunkport g0/0/1

                [sw1-Eth-Trunk0]trunkport g0/0/2

        SW2

                [sw2]int Eth-Trunk 0  
                [sw2-Eth-Trunk0]trunkport g0/0/1

                [sw2-Eth-Trunk0]trunkport g0/0/2

第二步：创建，划分VLAN，trunk干道

        SW1:

                [sw1]port-group group-member g0/0/3 to g 0/0/4 Eth-Trunk --- 创建接口组

                [sw1-port-group]port link-type trunk    ---连接类型trunk
[sw1-GigabitEthernet0/0/3]port link-type trunk 
[sw1-GigabitEthernet0/0/4]port link-type trunk 
[sw1-Eth-Trunk0]port link-type trunk  
                [sw1-port-group]port trunk allow-pass vlan 2  --- SW1允许VLAN2流量通过
[sw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2
[sw1-GigabitEthernet0/0/4]port trunk allow-pass vlan 2
[sw1-Eth-Trunk0]port trunk allow-pass vlan 2

        SW2:

                [sw2]port-group group-member g0/0/3 to g0/0/4 Eth-Trunk 0
                [sw2-port-group]port link-type trunk 
[sw2-GigabitEthernet0/0/3]port link-type trunk 
[sw2-GigabitEthernet0/0/4]port link-type trunk 
[sw2-Eth-Trunk0]port link-type trunk 
                [sw2-port-group]port trunk allow-pass vlan 2
[sw2-GigabitEthernet0/0/3]port trunk allow-pass vlan 2
[sw2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2
[sw2-Eth-Trunk0]port trunk allow-pass vlan 2

        SW5：

                [sw5]vlan 2
                [sw5-vlan2]q
                [sw5]int e0/0/2
                [sw5-Ethernet0/0/2]port link-type access  
                [sw5-Ethernet0/0/2]port default vlan 2
                [sw5]port-group group-member e0/0/3 to e0/0/4

                [sw5-port-group]port link-type trunk 
[sw5-Ethernet0/0/3]port link-type trunk 
[sw5-Ethernet0/0/4]port link-type trunk 

                [sw5-port-group]port trunk allow-pass vlan 2
[sw5-Ethernet0/0/3]port trunk allow-pass vlan 2
[sw5-Ethernet0/0/4]port trunk allow-pass vlan 2
[sw5-port-group]

        SW6：

                [sw6]vlan 2
                [sw6-vlan2]q
                [sw6]port-group group-member e0/0/3 to e0/0/4
                [sw6-port-group]port link-type trunk 
[sw6-Ethernet0/0/3]port link-type trunk 
[sw6-Ethernet0/0/4]port link-type trunk   
                [sw6-port-group]port trunk allow-pass vlan 2
[sw6-Ethernet0/0/3]port trunk allow-pass vlan 2
[sw6-Ethernet0/0/4]port trunk allow-pass vlan 2

                [sw6]int e0/0/2

                [sw6-Ethernet0/0/2]port link-type access    
                [sw6-Ethernet0/0/2]port default vlan 2

 第三步：做STP

        SW1

                [sw1]stp enable --- 启用stp协议
                [sw1]stp mode  mstp    --- stp模式
                [sw1]stp region-configuration ---stp配置
                [sw1-mst-region]region-name a  -- stp名字
                [sw1-mst-region]instance 1 vlan 1 ---主1放VLAN1
                [sw1-mst-region]instance 2 vlan 2
                [sw1-mst-region]active region-configuration ---激活配置

        SW2
                [sw2]stp enable   
                [sw2]stp mode mstp 
                [sw2]stp region-configuration   
                [sw2-mst-region]region-name a 
                [sw2-mst-region]instance 1 vlan 1
                [sw2-mst-region]instance 2 vlan 2
                [sw2-mst-region]active region-configuration 

        SW5

                [sw5]stp enable   
                [sw5]stp mode mstp 
                [sw5]stp region-configuration  
                [sw5-mst-region]region-name a   
                [sw5-mst-region]instance 1 vlan 1  
                [sw5-mst-region]instance 2 vlan 2
                [sw5-mst-region]active region-configuration

         SW6

                [sw6]stp enable 
                [sw6]stp mode mstp  
                [sw6]stp region-configuration    
                [sw6-mst-region]region-name a   
                [sw6-mst-region]instance 1 vlan 1 
                [sw6-mst-region]instance 2 vlan 2    
                [sw6-mst-region]active region-configuration

        SW1

                [sw1]stp instance 1 root primary

                [sw1]stp instance 2 root secondary 

        SW2

                [sw2]stp instance 2 root primary

                [sw2]stp instance 1 root secondary 

        SW6

                [sw6]port-group group-member e0/0/1 to e0/0/2
                [sw6-port-group]stp edged-port enable 
[sw6-Ethernet0/0/1]stp edged-port enable 
[sw6-Ethernet0/0/2]stp edged-port enable

                [sw1-Vlanif1]vrrp vrid 1 priority 105 --- 修改优先级

                [sw1-Vlanif1]vrrp vrid 1 track interface GigabitEthernet 0/0/1 reduced 6 --- 坏了降6，让网关。

                [sw1-Vlanif2]vrrp vrid  1 virtual-ip 172.16.1.254
