小型企業(yè)網(wǎng)組網(wǎng)方案—IP地址規(guī)劃及路由配置118小型企業(yè)網(wǎng)組網(wǎng)方案—IP學生姓名:XX指導教師:吳佳英IP度快的OSPF協(xié)議。其中用到的路由交換協(xié)議還有支持VLAN間數(shù)據(jù)傳輸?shù)腣TP協(xié)議。我們承受Cisco交換機帶寬聚合技術將多條物理線路捆綁為一條規(guī)律鏈路，使VLANVPNGNS3擬實現(xiàn)。，OSPF，VLAN，GNS31引言在現(xiàn)在的社會背景下，一個企業(yè)要提升競爭力，就必需實現(xiàn)公司信息化，甚至可以說，沒有公司的信息化就沒有競爭力。公司信息化指將信息網(wǎng)絡技術、計算Internet下，公司也就要相應地做出信息化的戰(zhàn)略選擇。承受先進的網(wǎng)絡技術，對承受TCP/IP協(xié)議的殘聯(lián)網(wǎng)絡的IP地址及域名進展統(tǒng)一安排，以便于有效實現(xiàn)全國殘聯(lián)TCP/IP，IP《小型企業(yè)網(wǎng)組網(wǎng)方案—IP218InternetIP址分為三類:A0，7241416地址;C110，218址。本文主要內(nèi)容IPIPIP劃設計測試結(jié)果，第四節(jié)是完畢語，對本次課程設計的總結(jié)。試驗平臺GNS3Windows,Linux,andMacOSCiscoCCNA,CCNP,CCIECiscoIOS的路由器上部署實施的相關配置。操作界面如圖1-1所示:1-1GNS33182設計原理及要求IPIPIPIP統(tǒng)一規(guī)劃并得到有效實施。IP到網(wǎng)絡應用的進一步進展。IPIPCPU、內(nèi)存址的可治理性。IP唯一性:一個IP網(wǎng)絡中不能有兩個主機承受一樣的IP地址;可治理性:地址安排應簡潔且易于治理，以降低網(wǎng)絡擴展的簡潔性，簡化路由表;連續(xù)性:連續(xù)地址在層次構(gòu)造網(wǎng)絡中易于進展路徑疊合，縮減路由表，提高路由計算的效率;IPVLSMIP小網(wǎng)絡中播送的路由信息的大小。IP可擴展性:地址安排在每一層次上都要留有確定余量，以便在網(wǎng)絡擴展時能保性，并為將來的網(wǎng)絡擴展預留確定的地址空間;充分利用無類別域間路由(CIDR)技術和變長子網(wǎng)掩碼(VLSM)IP機、效勞《小型企業(yè)網(wǎng)組網(wǎng)方案—IP地址規(guī)劃及路由配置》第4頁共18安全策略把握。靈敏性:地址安排應具有靈敏性，以滿足多種路由策略的優(yōu)化，充分利用地址空間;層次性:IP地址的劃分承受層次化的方法，和層次化的網(wǎng)絡設計相應，在地址劃南苑、家屬區(qū)，使地址具有層次性，能夠逐層向上會聚。loopback地址、設備間互連地址;IP小的子網(wǎng)，既節(jié)約了IP地址，同時可削減子網(wǎng)內(nèi)網(wǎng)絡風暴，提高網(wǎng)絡性能。路由原理路由器供給了異構(gòu)網(wǎng)互聯(lián)的機制，實現(xiàn)將一個網(wǎng)絡的數(shù)據(jù)包發(fā)送到另一個網(wǎng)IP包發(fā)送過程中事先商定好的規(guī)定和標準。為到達路由快速收斂、尋址以及便利網(wǎng)絡治理員治理的目的，我們承受動態(tài)路OSPFEIGRP協(xié)議，OSPF以協(xié)議標準EIGRPCisco公司制造，只有CiscoOSPF(Link-state)的路由協(xié)議，一般用于同一個路由域內(nèi)。在這里，路由域是指一個自治系統(tǒng)(AutonomousSystemAS，它AS中，全部的OSPF路由器都維護一個一樣的描述這個AS構(gòu)造的數(shù)據(jù)庫，該數(shù)據(jù)庫中存放的是路由域中相應鏈路的狀態(tài)信息，OSPFOSPFOSPFLSA(LinkStateAdvertisement)傳送給在某一區(qū)域內(nèi)的全部路由器，這一點與距遞給與其相鄰的路由器。《小型企業(yè)網(wǎng)組網(wǎng)方案—IP地址規(guī)劃及路由配置》第5頁共18OSPF協(xié)議承受鏈路狀態(tài)協(xié)議算法，每個路由器維護一個一樣的鏈路狀態(tài)數(shù)據(jù)庫AS的拓撲構(gòu)造(AS不劃分狀況下)。一旦每個路由器有了完整的鏈路狀態(tài)數(shù)據(jù)庫，該路由器就可以自己為根，構(gòu)造最短路徑樹，然后再依據(jù)最短路徑構(gòu)造路由表。對于大型的網(wǎng)絡，為了進一步削減路由協(xié)議通信流量，利于治理和計算。OSPF將整個AS劃分為假設干個區(qū)域，區(qū)域內(nèi)的路由器維護一個一樣的鏈路狀態(tài)數(shù)據(jù)庫，保存該區(qū)域的拓撲構(gòu)造。OSPF路由器相互間交換信息，但交換的信息不是路由，而是鏈路狀態(tài)。OSPF5種分組:Hello描述分組初始化路由器的網(wǎng)絡拓撲數(shù)據(jù)庫;當覺察數(shù)據(jù)庫中的某局部信息已經(jīng)過時由于OSPF直接運行在IP層，協(xié)議本身要供給確認機制，鏈路狀態(tài)應答分組是對鏈路狀態(tài)更分組進展確認。相對于其它協(xié)議，OSPF有很多優(yōu)點。OSPF支持各種不同鑒別機制(如簡潔口令驗證，MD5負載均衡功能，假設計算出到某個目的站有假設干條費用一樣的路由，OSPF路由器會把通信流量均勻地安排給這幾條路由，沿這幾條路由把該分組發(fā)送出去;在一OSPF路由實現(xiàn)的工作量;OSPF屬動態(tài)的自適應協(xié)議，對于網(wǎng)絡的拓撲構(gòu)造的通信流量;OSPF供給點到多點接口，支持CIDR(無類型域間路由)地址。area0，內(nèi)部網(wǎng)絡設備area0。后期假設有分支機構(gòu)各區(qū)域接入路由器依據(jù)區(qū)域不同使用動態(tài)協(xié)議，或者使用靜態(tài)路由與動態(tài)路由結(jié)合的方式。6183企業(yè)內(nèi)IP規(guī)劃及路由配置IP3-13-1IP《小型企業(yè)網(wǎng)組網(wǎng)方案—IP地址規(guī)劃及路由配置》第7頁共18是:市場部，人事部，工程部，研發(fā)部，財務部，駐外辦事處。每個部門相應的LIAN40，80，100，120，160，IP192.16.4.0/24，192.16.8.0/24，192.16.10.0/24，192.16.12.0/24，192.16.16.0/24，92.16.222.0/24具體劃分見表3-1:3-1Vlan40192.16.4.0/24人事部80192.16.8.0/24工程部100192.16.10.0/24研發(fā)部120192.16.12.0/24財務部160192.16.16.0/24駐外辦事處無需Vlan192.16.222.0/24OSPF(OpenShortestPathFirst(InteriorGatewayProtocolIGPTunnelOSPFVPN配置步驟Vlan:vlandatabaseVlan:L2Switch_1#vlandatabaseL2Switch_1(vlan)#vlan120VLAN120added:Name:VLAN0120L2Switch_1(vlan)#vlan160VLAN160added:Name:VLAN0160L2Switch_1(vlan)#exit818APPLYcompleted.Exiting....TrunkinterfaceFastEthernet0/0Vlan:Vlan:interfaceFastEthernet0/1switchportaccessvlan160interfaceFastEthernet0/2switchportaccessvlan160interfaceFastEthernet0/3switchportaccessvlan160interfaceFastEthernet0/4switchportaccessvlan160interfaceFastEthernet0/5switchportaccessvlan160interfaceFastEthernet0/6switchportaccessvlan160interfaceFastEthernet0/7switchportaccessvlan160interfaceFastEthernet0/8switchportaccessvlan120interfaceFastEthernet0/9switchportaccessvlan120interfaceFastEthernet0/10switchportaccessvlan120interfaceFastEthernet0/11switchportaccessvlan120interfaceFastEthernet0/12switchportaccessvlan120interfaceFastEthernet0/13918switchportaccessvlan120interfaceFastEthernet0/14switchportaccessvlan120interfaceFastEthernet0/15switchportaccessvlan120L3Switch_1Vlan:Vlan，IP:interfaceFastEthernet0/1noswitchportipaddress172.16.55.1255.255.255.0interfaceFastEthernet0/2noswitchportipaddress172.16.57.1255.255.255.0VLANSVI:VLAN關地址。interfaceVlan120ipaddress172.16.12.1255.255.255.0interfaceVlan160255.255.255.0TrunkTrunkVLANinterfaceFastEthernet0/3switchportmodetrunkinterfaceFastEthernet0/4switchportmodetrunkDNSIPipdhcppoolDHCP_120network172.16.12.0255.255.255.0default-router172.16.12.11018dns-server172.16.200.11ipdhcppoolDHCP_160network172.16.16.0255.255.255.0default-router172.16.16.1dns-server172.16.200.11IP，OSPF由，同routerospf100log-adjacency-changesnetwork172.16.12.00.0.0.255area0network172.16.16.00.0.0.255area0network172.16.55.00.0.0.255area0network172.16.57.00.0.0.255area0LoopbackinterfaceLoopback0ipaddress1.1.1.1255.255.255.0路由，所以應當配置靜態(tài)路由到接入外網(wǎng)的了，通過路由查詢，照舊可以到達路由器上。iproute0.0.0.00.0.0.0172.16.61.2IP:interfaceFastEthernet0/0noswitchportipaddress172.16.59.1255.255.255.0int
