以上這道CCNA綜合實驗題來自於2010年湖南省計算機應用網絡管理員的一道操做題,看上去很容易,但對於基礎知識掌握不牢固且對Packet tracer 這個cisco模擬器不熟悉的人在規定的時間內要全都配置好仍是有必定的困難的,下面我就這道綜合題來一一解答:web
首先咱們得先看明白本實驗的需求(我總結了一下,一共有十一點):安全
1,internet是ospf區域,不能經過OSPF邊緣路由器來增長到各企業網絡
的靜態路由,通告全部的本地直連的網絡。
2,R1-R3 FR-DLCI任意。
3,分公司和總部都需NAT轉換上網
4,SW1-SW2兩交換機間實現跨交換機互通,並經過端口聚合增長帶寬,
5,總部與分部都經過一條默認路由通達INTERNET。
6,分部出口路由器與INTERNET之間是PPP封裝,
7,R1與R2之間PPP,PAP認證。
8,vlan 10只能ping通vlan 20 的www服務
9,W3交換機爲了局域網安全須要作相應的端口安全設置,並綁定相應的
網與IP
10,由於vlan 10須要PC62臺,vlan 20須要280多臺PC,須要對172.16.0.0/16
進行VLSM劃分,以最省IP地址的形式劃分VLAN。
11,server 0 充當DNS與web 服務器,而且總部與分部都能訪問web資源。
那麼咱們能夠從以上需求看出須要作的配置大概有這幾個:端口聚合,VLSM劃分,ACL訪問控制,NAT網絡地址轉換,PPP封裝,PPP PAP認證,frame-relay幀中繼,端口安全,IP與MAC綁定,OSPF路由,VLAN劃分,DNS WEB配置,VTPvlan 中繼協議。既然分析了這些需求,那麼咱們如今就能夠用packet tracer去配置本實驗了。服務器
咱們分步進行,順序依次是總部-----INTERNET-----分部,網絡
總部配置以下:less

-------------------------------應用服務器的配置就不去寫了-----------
接下來就來看一下測試結果吧,
1,測試總部與INTERNET連通性:
2,測試分部與INTERNE連通性:

4,測試NAT是否生效:
測試語句:
結果:
。。。好吧,剩下的我也就再也不贅述了,但願可以經過此實驗讓各位都能強化一下網絡基礎知識,爲掌握更好的網絡技術而努力!
