要求如图，着实让我有点头大…
那么开始规划
首先配置Eth-Trunk
SW1:
[Huawei]int Eth-Trunk 0
[Huawei-Eth-Trunk0]q
[Huawei]int g 0/0/1
[Huawei-GigabitEthernet0/0/1]eth-trunk 0
Info: This operation may take a few seconds. Please wait for a moment…done.
[Huawei-GigabitEthernet0/0/1]int g 0/0/2
[Huawei-GigabitEthernet0/0/2]eth-trunk 0
Info: This operation may take a few seconds. Please wait for a moment…done.
SW2:
[sw2]int Eth-Trunk 0
[sw2-Eth-Trunk0]int g 0/0/1
[sw2-GigabitEthernet0/0/1]eth-trunk 0
Info: This operation may take a few seconds. Please wait for a moment…done.
[sw2-GigabitEthernet0/0/1]int g 0/0/2
[sw2-GigabitEthernet0/0/2]eth-trunk 0
Info: This operation may take a few seconds. Please wait for a moment…done.
接下来配置VLAN ( 记得先创建VLAN )
SW1:
[sw1]interface Eth-Trunk 0
[sw1-Eth-Trunk0]port link-type trunk
[sw1-Eth-Trunk0]port trunk allow-pass vlan 1 to 2
[sw1-Eth-Trunk0]q

[sw1]interface GigabitEthernet 0/0/5
[sw1-GigabitEthernet0/0/5]port link-type access
[sw1-GigabitEthernet0/0/5]port default vlan 3
[sw1]interface GigabitEthernet 0/0/3
[sw1-GigabitEthernet0/0/3]port hybrid tagged vlan 1 to 2
[sw1-GigabitEthernet0/0/3]int g 0/0/4
[sw1-GigabitEthernet0/0/4]port hybrid tagged vlan 1 to 2
SW2:
[sw2]interface Eth-Trunk 0
[sw2-Eth-Trunk0]port link-type trunk
[sw2-Eth-Trunk0]port trunk allow-pass vlan 1 to 2
[sw2-Eth-Trunk0]int g 0/0/5
[sw2-GigabitEthernet0/0/5]port link-type access
[sw2-vlan4]q
[sw2]int GigabitEthernet 0/0/5
[sw2-GigabitEthernet0/0/5]port link-type a
[sw2-GigabitEthernet0/0/5]port default vlan 4
[sw2-GigabitEthernet0/0/5]q
[sw2]interface g 0/0/3
[sw2-GigabitEthernet0/0/3]port hybrid tagged vlan 1 to 2
[sw2-GigabitEthernet0/0/3]int g 0/0/4
[sw2-GigabitEthernet0/0/4]port hybrid tagged vlan 1 to 2
SW3:
[sw3]int g 0/0/1
[sw3-GigabitEthernet0/0/1]port hybrid tagged vlan 1 to 2
[sw3-GigabitEthernet0/0/1]int g 0/0/2
[sw3-GigabitEthernet0/0/2]port hybrid tagged vlan 1 to 2
[sw3-GigabitEthernet0/0/2]int e 0/0/1
[sw3-Ethernet0/0/1]p l a (默认vlan1）
[sw3-Ethernet0/0/1]int e 0/0/2
[sw3-Ethernet0/0/2]p l a
[sw3-Ethernet0/0/2]port default vlan 2
SW4:
[sw4]int g 0/0/1
[sw4-GigabitEthernet0/0/1]port hybrid tagged vlan 1 to 2
[sw4-GigabitEthernet0/0/1]int g 0/0/2
[sw4-GigabitEthernet0/0/2]port hybrid tagged vlan 1 to 2
[sw4-GigabitEthernet0/0/2]int e 0/0/1
[sw4-Ethernet0/0/1]p l a
[sw4-Ethernet0/0/1]int e 0/0/2
[sw4-Ethernet0/0/2]p l a
[sw4-Ethernet0/0/2]port default vlan 2
STP
SW1:
[sw1]stp region-configuration
[sw1-mst-region]region-name xbox
[sw1-mst-region]instance 1 vlan 1
[sw1-mst-region]instance 2 vlan 2
[sw1-mst-region]active region-configuration
Info: This operation may take a few seconds. Please wait for a moment…done.
[sw1-mst-region]q
[sw1]stp instance 1 root primary
[sw1]stp instance 2 root secondary
SW2:
[sw2]stp region-configuration
[sw2-mst-region]region-name xbox
[sw2-mst-region]instance 1 vlan 1
[sw2-mst-region]instance 2 vlan 2
[sw2-mst-region]active region-configuration
Info: This operation may take a few seconds. Please wait for a moment…done.
[sw2-mst-region]q
[sw2]stp instance 1 root secondary
[sw2]stp instance 2 root primary
SW3:
[sw3]stp region-configuration
[sw3-mst-region]region-name xbox
[sw3-mst-region]instance 1 vlan 1

[sw4-mst-region]active region-configuration
配置SVI
SW1:
[sw1-Vlanif1]ip add 172.16.1.1 24
[sw1-Vlanif2]ip add 172.16.2.1 24
SW2:
[sw2-Vlanif1]ip add 172.16.1.2 24
[sw2-Vlanif2]ip add 172.16.2.2 24
VRRP
SW1:
[sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.254
[sw1-Vlanif1]vrrp vrid 1 priority 120
[sw1-Vlanif1]vrrp vrid 1 track int g 0/0/5 reduced 20
[sw1-Vlanif2]vrrp vrid 2 virtual-ip 172.16.2.254
[sw1-Vlanif2]vrrp vrid 2 priority 120
[sw1-Vlanif2]vrrp vrid 2 track interface GigabitEthernet 0/0/5 reduced 20
SW2:

[sw2-Vlanif2]vrrp vrid 2 track interface GigabitEthernet 0/0/5 reduced 20
配置DHCP
SW1:
[sw1]dhcp enable
[sw1]ip pool ns
Info:It’s successful to create an IP address pool.
[sw1-ip-pool-ns]network 172.16.1.0 mask 255.255.255.0
[sw1-ip-pool-ns]gateway-list 172.16.1.254
[sw1-ip-pool-ns]dns-list 114.114.114.114 8.8.8.8
[sw1-ip-pool-ns]q
[sw1]ip pool ps
Info:It’s successful to create an IP address pool.
[sw1-ip-pool-ps]network 172.16.2.0 mask 255.255.255.0
[sw1-ip-pool-ps]gateway-list 172.16.2.254
[sw1-ip-pool-ps]dns-list 114.114.114.114 8.8.8.8
[sw1]int v1
[sw1-Vlanif1]dhcp select global
[sw1-Vlanif1]int v2
[sw1-Vlanif2]dhcp select global
SW2:
[sw2]dhcp enable
[sw2]ip pool ns
[sw2-ip-pool-ns]network 172.16.1.0 mask 255.255.255.0
[sw2-ip-pool-ns]gateway-list 172.16.1.254

[sw2-ip-pool-ps]q
[sw2]int v1
[sw2-Vlanif1]dhcp select global
[sw2-Vlanif1]int v2
[sw2-Vlanif2]dhcp select global
看一下pc能否自动获取ip
一切正常，pc3和pc4也能获取
配置IP：
SW1:
[sw1-Vlanif2]int v3
[sw1-Vlanif3]ip add 172.16.3.1 24
SW2:
[sw2]int v4
[sw2-Vlanif4]ip add 172.16.4.1 24
R2:
[r2]int g 0/0/1
[r2-GigabitEthernet0/0/1]ip add 172.16.3.2 24
[r2-GigabitEthernet0/0/1]int g 0/0/2
[r2-GigabitEthernet0/0/2]ip add 172.16.4.2 24
[r2-GigabitEthernet0/0/2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 7.7.7.1 24
R1:
[r1]int loo0
[r1-LoopBack0]ip add 6.6.6.1 24
[r1-LoopBack0]int g 0/0/0
[r1-GigabitEthernet0/0/0]ip add 7.7.7.2 24
配置路由
r2]ip route-static 172.16.1.0 24 172.16.3.1
[r2]ip route-static 172.16.1.0 24 172.16.4.1
[r2]ip route-static 172.16.2.0 24 172.16.4.1
[r2]ip route-static 172.16.2.0 24 172.16.3.1
[sw1]ip route-static 0.0.0.0 0 172.16.3.2
[sw2]ip route-static 0.0.0.0 0 172.16.4.2
[r2]acl 2000
[r2-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r2-acl-basic-2000]int g 0/0/0
[r2-GigabitEthernet0/0/0]nat outbound 2000
然后pc1正常情况下ping6.6.6.1
接着关闭sw1 ping 6.6.6.1
虽然一开始断了但很快又通了
