综合项目

工具：ENSP
如图创建拓扑图

在这里插入图片描述

第一步：创建交换机各VLAN

[SW1]vlan batch 10 20 30 40 100
[SW2]vlan batch 10 20 30 40 100
[SW3]vlan batch 10 20 30 40 100
[SW4]vlan batch 10 20 30 40 100
[SW5]vlan batch 10 20 30 40 100

第二步：设置接口属性

[SW1-GigabitEthernet0/0/1]port link-type access 
[SW1-GigabitEthernet0/0/1]port default vlan 10
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 20
[SW1-GigabitEthernet0/0/3]port link-type trunk
[SW1-GigabitEthernet0/0/3]port trunk allow-pass vlan all
[SW1-GigabitEthernet0/0/4]port link-type trunk
[SW1-GigabitEthernet0/0/4]port trunk allow-pass vlan all //交换机SW1接口配置

[SW2-GigabitEthernet0/0/1]port link-type access
[SW2-GigabitEthernet0/0/1]port default vlan 10

[SW2-GigabitEthernet0/0/2]port default vlan 20
[SW2-GigabitEthernet0/0/3]port link-type trunk
[SW2-GigabitEthernet0/0/3]port trunk allow-pass vlan all
[SW2-GigabitEthernet0/0/4]port link-type trunk 
[SW2-GigabitEthernet0/0/4]port trunk allow-pass vlan all //交换机SW2接口配置

[SW3]port-group group-member g0/0/1 to g0/0/3

[SW4-port-group]port trunk allow-pass vlan all
[SW4-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[SW4-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[SW4-GigabitEthernet0/0/3]port trunk allow-pass vlan all
 //交换机SW4接口配置

[SW5-GigabitEthernet0/0/1]port link-type access 
[SW5-GigabitEthernet0/0/1]port default vlan 100
[SW5-GigabitEthernet0/0/2]port link-type trunk
[SW5-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[SW5-GigabitEthernet0/0/3]port link-type trunk
[SW5-GigabitEthernet0/0/3]port trunk allow-pass vlan all //交换机SW5接口配置

第三步：设置汇入层交换机链路聚合

[SW3]interface Eth-Trunk 0  //设置链路聚合组0
[SW3-Eth-Trunk0]trunkport g0/0/10 
[SW3-Eth-Trunk0]trunkport g0/0/11 //将g0/0/10和g0/0/11 接口加入链路组
[SW3-Eth-Trunk0]port link-type trunk
[SW3-Eth-Trunk0]port trunk allow-pass vlan all //允许所有vlan通过
 /*汇入层交换机SW3配置 */
[SW4]interface Eth-Trunk 0  //设置链路聚合组0
[SW4-Eth-Trunk0]trunkport g0/0/10
[SW4-Eth-Trunk0]trunkport g0/0/11 //将g0/0/10和g0/0/11 接口加入链路组
[SW4-Eth-Trunk0]port link-type trunk
[SW4-Eth-Trunk0]port trunk allow-pass vlan all //允许所有vlan通过
 /*汇入层交换机SW4配置 */

验证聚合路由是否设置完成

[SW3]display interface Eth-Trunk 0  //使用命令查看链路聚合组是否联通
Eth-Trunk0 current state : UP
Line protocol current state : UP
Description:
Switch Port, PVID :    1, Hash arithmetic : According to SIP-XOR-DIP,Maximal BW:

    Input bandwidth utilization  :    0%
    Output bandwidth utilization :    0%
-----------------------------------------------------
PortName                      Status      Weight
-----------------------------------------------------
GigabitEthernet0/0/10         UP          1
GigabitEthernet0/0/11         UP          1
-----------------------------------------------------
The Number of Ports in Trunk : 2
The Number of UP Ports in Trunk : 2

第四步：将VLAN加入虚接口

[SW3-Vlanif10]ip address 192.168.10.254 24
[SW3-Vlanif20]ip address 192.168.20.254 24
[SW3-Vlanif30]ip address 192.168.30.254 24
[SW3-Vlanif40]ip address 192.168.40.254 24
[SW3-Vlanif100]ip address 192.168.100.254 24 //交换机SW3的虚接口配置

[SW4-Vlanif10]ip address 192.168.10.253 24
[SW4-Vlanif20]ip address 192.168.20.253 24
[SW4-Vlanif30]ip address 192.168.30.253 24
[SW4-Vlanif40]ip address 192.168.40.253 24
[SW4-Vlanif100]ip address 192.168.100.253 24 //交换机SW4的虚接口配置

第五步：配置生成树协议

[SW3]stp mode mstp            //使用Mstp生成树协议
[SW3]stp region-configuration  //stp区域配置
[SW3-mst-region]region-name huawei  // stp区域名称
[SW3-mst-region]revision-level 1   //区域修订版本级别
[SW3-mst-region]instance 10 vlan 10 100 //实例10 映射VLAN10和100 
[SW3-mst-region]instance 20 vlan 20 //实例20 映射VLAN 20
[SW3-mst-region]active region-configuration //激活生成树配置
[SW3]stp instance 10 priority 0  
[SW3]stp instance 20 priority 4096   //配置交换机通过stp优先级

[SW4]stp mode mstp
[SW4]stp region-configuration 
[SW4-mst-region]region-name huawei
[SW4-mst-region]revision-level 1
[SW4-mst-region]instance 10 vlan 10 100
[SW4-mst-region]instance 20 vlan 20
[SW4-mst-region]active region-configuration
[SW4]stp instance 10 priority 4096
[SW4]stp instance 20 priority 0  // 交换机SW4生成树配置

[SW1]stp mode mstp
[SW1]stp region-configuration
[SW1-mst-region]region-name huawei
[SW1-mst-region]revision-level 1
[SW1-mst-region]instance 10 vlan 10 100
[SW1-mst-region]instance 20 vlan 20
[SW1-mst-region]active region-configuration //交换机SW1生成树配置

[SW2]stp mode mstp
[SW2]stp region-configuration
[SW2-mst-region]region-name huawei
[SW2-mst-region]revision-level 1
[SW2-mst-region]instance 10 vlan 10 100
[SW2-mst-region]instance 20 vlan 20
[SW2-mst-region]active region-configuration //交换机SW2生成树配置

[SW5]stp region-configuration
[SW5-mst-region]region-name huawei
[SW5-mst-region]revision-level 1
[SW5-mst-region]instance 10 vlan 10 100
[SW5-mst-region]instance 20 vlan 20
[SW5-mst-region]active region-configuration //交换机SW5生成树配置

第六步：使用路由器充当DHCP服务器角色

[DHCPSERVER]dhcp enable //开启dhcp服务
[DHCPSERVER-GigabitEthernet0/0/0]ip address 192.168.100.100 24
/* 这里没配置默认路由是因为需要配置VRRP的虚拟IP地址下一跳 */
[DHCPSERVER]ip pool vlan10 //创建VLAN10的地址池
[DHCPSERVER-ip-pool-vlan10]network 192.168.10.0 mask 24 //网段
[DHCPSERVER-ip-pool-vlan10]gateway-list 192.168.10.100 //虚拟网关
[DHCPSERVER-ip-pool-vlan10]dns-list 8.8.8.8  //dns服务器设置
[DHCPSERVER]ip pool vlan20 //创建VLAN20的地址池
[DHCPSERVER-ip-pool-vlan20]network 192.168.20.0 mask 24 //网段
[DHCPSERVER-ip-pool-vlan20]gateway-list 192.168.20.100 //虚拟网关
[DHCPSERVER-ip-pool-vlan20]dns-list 8.8.8.8 //dns服务器设置
[DHCPSERVER]int g0/0/0
[DHCPSERVER-GigabitEthernet0/0/0]dhcp select global //dhcp选择全局

第七步：设置汇聚层交换机DHCP中继模式

[SW3]dhcp enable //开启dhcp服务
[SW3-Vlanif10]dhcp select relay   //dhcp选择中继模式
[SW3-Vlanif10]dhcp relay server-ip 192.168.100.100 //dhcp服务器地址
[SW3-Vlanif20]dhcp select relay  //dhcp选择中继模式
[SW3-Vlanif20]dhcp relay server-ip 192.168.100.100 //dhcp服务器地址
 //汇入层交换机SW3配置

[SW4]dhcp enable  //开启dhcp服务
[SW4-Vlanif10]dhcp select relay  //dhcp选择中继模式
[SW4-Vlanif10]dhcp relay server-ip 192.168.100.100 //dhcp服务器地址
[SW4-Vlanif20]dhcp select relay  //dhcp选择中继模式
[SW4-Vlanif20]dhcp relay server-ip 192.168.100.100 //dhcp服务器地址
 //汇入层交换机SW4配置

第八步：进入接入层交换机配置VRRP服务<虚拟路由冗余协议>

/*接入层交换机SW3的VRRP配置 */
[SW3-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.100 //启用VRRP服务 虚拟地址192.168.10.100
[SW3-Vlanif10]vrrp vrid 10 priority 120 //设置优先级120 默认100
[SW3-Vlanif10]vrrp vrid 10 preempt-mode  timer delay 1 //抢占模式延迟1秒
[SW3-Vlanif20]vrrp vrid 20 virtual-ip 192.168.20.200 //启用VRRP服务 虚拟地址192.168.20.200
[SW3-Vlanif100]vrrp vrid 100 virtual-ip 192.168.100.200 //启用VRRP服务 虚拟地址192.168.100.200
[SW3-Vlanif100]vrrp vrid 100 priority 120 //设置优先级120 默认100
[SW3-Vlanif100]vrrp vrid 100 preempt-mode timer delay 1 //抢占模式延迟1秒

/*接入层交换机SW4的VRRP配置 */
[SW4-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.100 //启用VRRP服务 虚拟地址192.168.10.100
[SW4-Vlanif20]vrrp vrid 20 virtual-ip 192.168.20.200 //启用VRRP服务 虚拟地址192.168.20.200
[SW4-Vlanif20]vrrp vrid 20 priority 120 //设置优先级120 默认100
[SW4-Vlanif20]vrrp vrid 20 preempt-mode timer delay 1 //抢占模式延迟1秒
[SW4-Vlanif100]vrrp vrid 100 virtual-ip 192.168.100.200 //启用VRRP服务 虚拟地址192.168.100.200

第九步：设置dhcp服务器的默认路由<下一跳为两台路由器虚拟出来的地址>

[DHCPSERVER]ip route-static 0.0.0.0 0.0.0.0 192.168.100.200

验证！

PC>ipconfig /release  //释放IP地址

IP Configuration

[BOWA-ZONGBU-GigabitEthernet0/0/1]ip address 192.168.40.1 24
[BOWA-ZONGBU-GigabitEthernet0/0/2]ip address 222.210.1.1 24

第十三步：设置汇聚层交换机上行接口属性

[SW3-GigabitEthernet0/0/4]port link-type access
[SW3-GigabitEthernet0/0/4]port default vlan 30  //汇聚层交换机SW3配置

<BOWA-ZONGBU>ping 192.168.30.254   //验证 使用总部路由器ping vlan30网关

    round-trip min/avg/max = 50/60/100 ms

第十四步：启用动态路由协议 ospf

/*汇聚层交换机SW3的动态路由宣告 */
[SW3]ospf 1 router-id 1.1.1.1 //ospf身份识别号码 点分十进制
[SW3-ospf-1]area 0 //进入骨干区域0 
[SW3-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.255.255 //宣告直连路由 可以精确 但是本拓扑图在同一大网段 可以进行粗略宣告

/*汇聚层交换机SW4的动态路由宣告 */
[SW4]ospf 1 router-id 2.2.2.2 //ospf身份识别号码 点分十进制
[SW4-ospf-1]area 0 //进入骨干区域0 
[SW4-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.255.255 //宣告直连路由 可以精确 但是本拓扑图在同一大网段 可以进行粗略宣告

/*公司总部路由器的动态路由宣告 */
[BOWA-ZONGBU]ospf 1 router-id 3.3.3.3 //ospf身份识别号码 点分十进制
[BOWA-ZONGBU-ospf-1]area 0 //进入骨干区域0 
[BOWA-ZONGBU-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.255.255
[BOWA-ZONGBU-ospf-1-area-0.0.0.0]network 10.0.0.0 0.0.0.255 //因为还有10.0.0.0网段
//宣告直连路由 可以精确 但是本拓扑图在同一大网段 可以进行粗略宣告
[BOWA-ZONGBU-ospf-1]default-route-advertise //宣告默认路由

[BOWA-ZONGBU-ospf-1]display ip routing-table //使用命令查看总部ospf学习情况

第十五步：配置总部路由器默认地址
目的：公网有无数IP地址路由器无法进行学习ospf 如果学习会导致路由器崩溃

[BOWA-ZONGBU]ip route-static 0.0.0.0 0.0.0.0 222.210.1.2

验证：

PC>ping 172.10.1.1  //使用左下角PC ping最远分公司主机 验证成功

Ping 172.10.1.1: 32 data bytes, Press Ctrl_C to break
Request timeout!
From 172.10.1.1: bytes=32 seq=2 ttl=125 time=110 ms
From 172.10.1.1: bytes=32 seq=3 ttl=125 time=109 ms
From 172.10.1.1: bytes=32 seq=4 ttl=125 time=94 ms
From 172.10.1.1: bytes=32 seq=5 ttl=125 time=110 ms

--- 172.10.1.1 ping statistics ---
  5 packet(s) transmitted
  4 packet(s) received
  20.00% packet loss
  round-trip min/avg/max = 0/105/110 ms

第十六步：cloud云设置
如下图配置cloud
在这里插入图片描述
网卡设置

验证：使用本机电脑ping cloud公网IP地址 222.210.1.2

C:\Users\10649>ping  222.210.1.1  //验证成功

正在 Ping 222.210.1.1 具有 32 字节的数据:
来自 222.210.1.1 的回复: 字节=32 时间=8ms TTL=255
来自 222.210.1.1 的回复: 字节=32 时间=5ms TTL=255
来自 222.210.1.1 的回复: 字节=32 时间=11ms TTL=255
来自 222.210.1.1 的回复: 字节=32 时间=6ms TTL=255

222.210.1.1 的 Ping 统计信息:
    数据包: 已发送 = 4，已接收 = 4，丢失 = 0 (0% 丢失)，
往返行程的估计时间(以毫秒为单位):
    最短 = 5ms，最长 = 11ms，平均 = 7ms

第十七步：线路优化

[SW3-Vlanif10]vrrp vrid 10 track interface g0/0/4 reduced 30 //VRRP追踪上行链路  跟踪上行链路 如果g0/0/4口故障 减少30优先级

验证：

/*使用长ping 断开SW3的g0/0/4口发现很快恢复网络 优化线路成功 */
PC>ping 222.210.1.2 -t 

Ping 222.210.1.2: 32 data bytes, Press Ctrl_C to break
From 222.210.1.2: bytes=32 seq=1 ttl=126 time=78 ms
From 222.210.1.2: bytes=32 seq=2 ttl=126 time=94 ms
From 222.210.1.2: bytes=32 seq=3 ttl=126 time=78 ms
From 222.210.1.2: bytes=32 seq=4 ttl=126 time=94 ms
From 222.210.1.2: bytes=32 seq=5 ttl=126 time=125 ms
Request timeout!
From 222.210.1.2: bytes=32 seq=30 ttl=126 time=109 ms
From 222.210.1.2: bytes=32 seq=31 ttl=126 time=94 ms
From 222.210.1.2: bytes=32 seq=32 ttl=126 time=94 ms
From 222.210.1.2: bytes=32 seq=33 ttl=126 time=78 ms

From 222.210.1.2: bytes=32 seq=36 ttl=126 time=78 ms

--- 222.210.1.2 ping statistics ---
  36 packet(s) transmitted
  33 packet(s) received
  8.33% packet loss
  round-trip min/avg/max = 78/92/125 ms

实验完成：全网互通
实验中可能出现获取新IP地址报错重新换一台PC就好
