小型企业网组网方案—IP地址规划及路由配置118小型企业网组网方案—IP学生姓名:XX指导教师:吴佳英IP度快的OSPF协议。其中用到的路由交换协议还有支持VLAN间数据传输的VTP协议。我们承受Cisco交换机带宽聚合技术将多条物理线路捆绑为一条规律链路，使VLANVPNGNS3拟实现。，OSPF，VLAN，GNS31引言在现在的社会背景下，一个企业要提升竞争力，就必需实现公司信息化，甚至可以说，没有公司的信息化就没有竞争力。公司信息化指将信息网络技术、计算Internet下，公司也就要相应地做出信息化的战略选择。承受先进的网络技术，对承受TCP/IP协议的残联网络的IP地址及域名进展统一安排，以便于有效实现全国残联TCP/IP，IP《小型企业网组网方案—IP218InternetIP址分为三类:A0，7241416地址;C110，218址。本文主要内容IPIPIP划设计测试结果，第四节是完毕语，对本次课程设计的总结。试验平台GNS3Windows,Linux,andMacOSCiscoCCNA,CCNP,CCIECiscoIOS的路由器上部署实施的相关配置。操作界面如图1-1所示:1-1GNS33182设计原理及要求IPIPIPIP统一规划并得到有效实施。IP到网络应用的进一步进展。IPIPCPU、内存址的可治理性。IP唯一性:一个IP网络中不能有两个主机承受一样的IP地址;可治理性:地址安排应简洁且易于治理，以降低网络扩展的简洁性，简化路由表;连续性:连续地址在层次构造网络中易于进展路径叠合，缩减路由表，提高路由计算的效率;IPVLSMIP小网络中播送的路由信息的大小。IP可扩展性:地址安排在每一层次上都要留有确定余量，以便在网络扩展时能保性，并为将来的网络扩展预留确定的地址空间;充分利用无类别域间路由(CIDR)技术和变长子网掩码(VLSM)IP机、效劳《小型企业网组网方案—IP地址规划及路由配置》第4页共18安全策略把握。灵敏性:地址安排应具有灵敏性，以满足多种路由策略的优化，充分利用地址空间;层次性:IP地址的划分承受层次化的方法，和层次化的网络设计相应，在地址划南苑、家属区，使地址具有层次性，能够逐层向上会聚。loopback地址、设备间互连地址;IP小的子网，既节约了IP地址，同时可削减子网内网络风暴，提高网络性能。路由原理路由器供给了异构网互联的机制，实现将一个网络的数据包发送到另一个网IP包发送过程中事先商定好的规定和标准。为到达路由快速收敛、寻址以及便利网络治理员治理的目的，我们承受动态路OSPFEIGRP协议，OSPF以协议标准EIGRPCisco公司制造，只有CiscoOSPF(Link-state)的路由协议，一般用于同一个路由域内。在这里，路由域是指一个自治系统(AutonomousSystemAS，它AS中，全部的OSPF路由器都维护一个一样的描述这个AS构造的数据库，该数据库中存放的是路由域中相应链路的状态信息，OSPFOSPFOSPFLSA(LinkStateAdvertisement)传送给在某一区域内的全部路由器，这一点与距递给与其相邻的路由器。《小型企业网组网方案—IP地址规划及路由配置》第5页共18OSPF协议承受链路状态协议算法，每个路由器维护一个一样的链路状态数据库AS的拓扑构造(AS不划分状况下)。一旦每个路由器有了完整的链路状态数据库，该路由器就可以自己为根，构造最短路径树，然后再依据最短路径构造路由表。对于大型的网络，为了进一步削减路由协议通信流量，利于治理和计算。OSPF将整个AS划分为假设干个区域，区域内的路由器维护一个一样的链路状态数据库，保存该区域的拓扑构造。OSPF路由器相互间交换信息，但交换的信息不是路由，而是链路状态。OSPF5种分组:Hello描述分组初始化路由器的网络拓扑数据库;当觉察数据库中的某局部信息已经过时由于OSPF直接运行在IP层，协议本身要供给确认机制，链路状态应答分组是对链路状态更分组进展确认。相对于其它协议，OSPF有很多优点。OSPF支持各种不同鉴别机制(如简洁口令验证，MD5负载均衡功能，假设计算出到某个目的站有假设干条费用一样的路由，OSPF路由器会把通信流量均匀地安排给这几条路由，沿这几条路由把该分组发送出去;在一OSPF路由实现的工作量;OSPF属动态的自适应协议，对于网络的拓扑构造的通信流量;OSPF供给点到多点接口，支持CIDR(无类型域间路由)地址。area0，内部网络设备area0。后期假设有分支机构各区域接入路由器依据区域不同使用动态协议，或者使用静态路由与动态路由结合的方式。6183企业内IP规划及路由配置IP3-13-1IP《小型企业网组网方案—IP地址规划及路由配置》第7页共18是:市场部，人事部，工程部，研发部，财务部，驻外办事处。每个部门相应的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具体划分见表3-1:3-1Vlan40192.16.4.0/24人事部80192.16.8.0/24工程部100192.16.10.0/24研发部120192.16.12.0/24财务部160192.16.16.0/24驻外办事处无需Vlan192.16.222.0/24OSPF(OpenShortestPathFirst(InteriorGatewayProtocolIGPTunnelOSPFVPN配置步骤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关地址。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，所以应当配置静态路由到接入外网的了，通过路由查询，照旧可以到达路由器上。iproute0.0.0.00.0.0.0172.16.61.2IP:interfaceFastEthernet0/0noswitchportipaddress172.16.59.1255.255.255.0interfaceFastEthernet0/1noswitchportipaddress172.16.55.2255.255.255.0interfaceFastEthernet0/2noswitchport《小型企业网组网方案—IP地址规划及路由配置》第11页共18ipnoaddress172.16.58.2switchport255.255.255.0interfaceFastEthernet0/3ipaddress172.16.61.1255.255.255.0interfaceFastEthernet0/4noswitchportipnoaddress172.16.63.1switchport255.255.255.0interfaceFastEthernet0/5255.255.255.0OSPF:在与下层交换机连接的端IP，OSPFrouterospf100log-adjacency-changesnetwork172.16.53.00.0.0.255area0network172.16.55.00.0.0.255area0network172.16.58.00.0.0.255area0network172.16.59.00.0.0.255area0network172.16.61.00.0.0.255area0network172.16.63.00.0.0.255area0network172.16.200.00.0.0.255area0外网的路由，所以应当配置默认路由到接入外网的路由器上。iproute0.0.0.00.0.0.0172.16.61.2115，一旦与路由相连的一根线出问题时，通过浮动iproute0.0.0.00.0.0.0172.16.63.2115《小型企业网组网方案—IP地址规划及路由配置》第12页共18设计验证(
