綜合實驗1

實驗需求

總部

1.除了SW8和SW9是三層交換機，其他交換機均為二層交換機，需要做鏈路聚合的線路圖中已標出。所有交換機的接口模式按照圖中標出的位置。
思考問題：這個圖中有環路么？
2.GW為總部的出口設備，使用單臂路由技術，Vlan10，20，100的網關都在GW上。
3.總部、分支8、分支9之間互有專線連接。
目標：GW、SW8、SW9之間建立ospf，互相宣告互為鄰居，進程號200，區域0，達到企業內網全網互通。
4.在SW8和SW9建立的鄰居中，SW8的互聯接口要永遠為DR。
5.要求DHCP服務器在路由追蹤PC8時，路徑中必須包含SW9。

特性

6.Vlan10,20的PC均由DHCP服務器提供IP地址，DHCP服務器的地址池配置如下：
Vlan10：192.168.10.0/24 GW：192.168.10.254 DNS：8.8.8.8 租期：8天。
Vlan20：192.168.20.0/24 GW：192.168.20.254 DNS：8.8.8.8 租期：8天。
PC2是老板的PC，老板要求通過DHCP給他固定IP：192.168.20.100/24，其他與地址池一致。
由于員工區存在打印機，需要排除掉192.168.10.240-254 ， 192.168.20.240-254。
7.GW路由器使用NAT技術，配置Easy-IP技術讓內部設備可以上網
在Internet路由器上使用環回接口模擬公網地址，讓所有PC可以ping通100.1.1.1。
8.服務器區有一臺HTTP服務器，將其80端口發布到Internet網絡，在Internet路由器上使用telnet 70.1.1.1 80 來驗證是否成功。

分支8

PC8配置靜態IP使PC8可以通過總部GW上網，ping 100.1.1.1。

分支9

PC9配置靜態IP使PC9可以通過總部GW上網，ping 100.1.1.1。
