ciscoIP路由分解实验

cisco路由器实验报告Cisco路由器实验报告引言：在现代网络通信中，路由器是一个至关重要的设备。

它能够将数据包从源地址传输到目的地址，实现网络之间的连接和数据传输。

本实验旨在研究和探索Cisco路由器的功能和应用。

一、Cisco路由器的基本原理Cisco路由器是一种网络设备，它基于OSPF（开放最短路径优先）协议和BGP （边界网关协议）等路由协议工作。

其基本原理是将数据包从一个网络传输到另一个网络，通过查找路由表中的最佳路径来实现。

二、Cisco路由器的配置与管理1. 登录和基本设置通过串口或以太网口与路由器建立连接后，可以通过命令行界面（CLI）或Web 界面登录路由器进行配置和管理。

首次登录需要进行基本设置，如设置主机名、密码、IP地址等。

2. 路由配置路由配置是Cisco路由器的核心功能之一。

通过配置静态路由或动态路由协议，路由器可以学习到网络拓扑，并根据路由表进行数据包转发。

静态路由适用于小型网络，而动态路由协议适用于大型网络。

3. 接口配置路由器的接口配置非常重要，它决定了路由器与其他设备之间的连接方式和速率。

可以通过配置IP地址、子网掩码、MTU（最大传输单元）等参数来进行接口配置。

4. 安全性配置为了保护网络安全，Cisco路由器提供了多种安全功能和配置选项。

例如，可以配置访问控制列表（ACL）来限制特定IP地址的访问，还可以启用SSH（安全外壳协议）来加密远程登录会话。

三、Cisco路由器的高级功能1. VLAN（虚拟局域网）通过配置VLAN，可以将一个物理网络划分为多个逻辑网络，提高网络的灵活性和安全性。

Cisco路由器支持VLAN的创建和管理，可以实现不同VLAN之间的通信。

2. VPN（虚拟专用网络）VPN是一种通过公共网络建立安全连接的技术。

Cisco路由器支持IPSec （Internet协议安全）和SSL（安全套接字层）等VPN协议，可以实现远程办公和跨地域网络连接。

cisco路由器实验报告
《cisco路由器实验报告》
在网络通信领域，路由器是一种非常重要的设备，它可以实现不同网络之间的
数据传输和转发。

而cisco路由器作为全球领先的网络设备制造商，其产品在
市场上有着很高的知名度和影响力。

为了更好地了解和掌握cisco路由器的使
用和性能，我们进行了一系列的实验，并在此进行报告。

首先，我们对cisco路由器进行了基本的配置和连接，包括设置IP地址、子网
掩码、网关等基本网络参数。

在这一步骤中，我们深入了解了cisco路由器的
操作界面和命令行配置方式，对其操作和管理有了更深刻的认识。

其次，我们进行了路由器之间的互联实验，通过配置路由器之间的静态路由和
动态路由协议（如OSPF、EIGRP等），实现了不同网络之间的数据传输和转发。

在这个实验中，我们深入了解了cisco路由器的路由选择算法和路由表的构建
过程，对网络的数据传输和转发有了更深入的了解。

除此之外，我们还进行了一些高级功能的实验，如ACL（访问控制列表）的配
置和应用、NAT（网络地址转换）的配置和应用等。

这些实验让我们更加深入
地了解了cisco路由器在网络安全和地址转换方面的应用。

总的来说，通过这些实验，我们对cisco路由器的使用和性能有了更深入的了解，对网络通信的原理和技术有了更深刻的认识。

希望通过这份实验报告，可
以为更多对cisco路由器感兴趣的人提供一些参考和帮助。

同时，也希望cisco
路由器在未来的发展中能够更加完善和强大，为网络通信领域带来更多的创新
和进步。

路由是通过那个口来分配的。

接几个分配几个。

要使客户机能从用作DHCP Server的路由器中自动获得IP地址。

三、实验要求：1、vlan之间的通信通过三层交换机来实现2、路由器为4个vlan来分配ip地址3、pc1 - 4分别属于4个部门，能够自动得到ip地址4、pc1 - 5直接可以ping通四、实验思路：1、首先配置二层交换机上的vlan、trunk并把接口加入vlan2、三层交换中配置vlan、trunk并启用ip routing路由功能3、三层交换中配置vlan ip地址，三层交换机是带有三层路由功能的交换机，也就是这台交换机的端口既有三层路由功能，也具有二层交换功能。

三层交换机端口默认为二层口，如果需要启用三层功能就需要在此端口输入no switchport命令。

思科Cisco路由器RIP动态路由配置实验案例详解本⽂讲述了思科Cisco路由器RIP动态路由配置实验。

分享给⼤家供⼤家参考，具体如下：实验九　路由器RIP动态路由配置⼀、实验⽬的1. 掌握RIP协议的配置⽅法：2. 掌握查看通过动态路由协议RIP学习产⽣的路由；3. 熟悉⼴域⽹线缆的链接⽅式；⼆、实验背景 假设校园⽹通过⼀台三层交换机连到校园⽹出⼝路由器上，路由器再和校园外的另⼀台路由器连接。

现要做适当配置，实现校园⽹内部主机与校园⽹外部主机之间的相互通信。

为了简化⽹管的管理维护⼯作，学校决定采⽤RIPV2协议实现互通。

三、技术原理1. RIP(Routing Information Protocols,路由信息协议)是应⽤较早、使⽤较普遍的IGP内部⽹管协议，使⽤于⼩型同类⽹络，是距离⽮量协议；2. RIP协议跳数作为衡量路径开销的，RIP协议⾥规定最⼤跳数为15；3. RIP协议有两个版本：RIPv1和RIPv2，RIPv1属于有类路由协议，不⽀持VLSM，以⼴播形式进⾏路由信息的更新，更新周期为30秒；RIPv2属于⽆类路由协议，⽀持VLSM，以组播形式进⾏路由更细。

四、实验步骤 建⽴建⽴packet tracer拓扑图 （1）在本实验中的三层交换机上划分VLAN10和VLAN20，其中VLAN10⽤于连接校园⽹主机，VLAN20⽤于连接R1。

（2）路由器之间通过V.35电缆通过串⼝连接，DCE端连接在R1上，配置其时钟频率64000。

（3）主机和交换机通过直连线，主机与路由器通过交叉线连接。

（4）在S3560上配置RIPV2路由协议。

（5）在路由器R1、R2上配置RIPV2路由协议。

（6）将PC1、PC2主机默认⽹关设置为与直连⽹路设备接⼝IP地址。

（7）验证PC1、PC2主机之间可以互相同信；五、实验设备 PC 2台；Switch_3560 1台；Router-PT 2台；直连线；交叉线；DCE 串⼝线六、实验拓扑图七、实验命令PC1IP: 192.168.1.2Submask: 255.255.255.0Gateway: 192.168.1.1 PC2IP: 192.168.2.2Submask: 255.255.255.0Gateway: 192.168.2.1S3560enconf thostname S3560vlan 10exitvlan 20exitinterface fa 0/10switchport access vlan 10exitinterface fa 0/20switchport access valn 20exitendshow vlanconf tinterface vlan 10ip address 192.168.1.1 255.255.255.0no shutdownexitinterface vlan 20ip address 192.168.3.1 255.255.255.0no shutdownendshow ip routeshow runingconf trouter ripnetwork 192.168.1.0network 192.168.3.0version 2endshow ip routeR1enconf thostname R1interface fa 0/0no shutdownip address 192.168.3.2 255.255.255.0interface serial 2/0no shutdownip address 192.168.4.1 255.255.255.0clock rate 64000endshow ip routeconf trouter ripnetwork 192.168.3.0network 192.168.4.0version 2exitR2enconf thostname R2interface fa 0/0no shutdownip address 192.168.2.1 255.255.255.0interface serial 2/0no shutdownip address 192.168.4.2 255.255.255.0endshow ip routeconf trouter ripnetwork 192.168.2.0netword 192.168.4.0version 2end⼋、实验结果 配置PC0、PC1的IP地址： 配置S3560： 配置R1： 配置R2： PC0 ping PC1:。

实验的基本配置一、试验环境IP地址配置：步骤 1. 配置全局配置主机名设置：可以使用哪两个命令离开特权执行模式？exit和end。

可使用什么快捷命令进入特权执行模式？enable。

研究可以通过命令configure 进入的不同配置模式：Router&gt;enableRouter# configure terminal Router(config)#将设备的主机名设为Router1：router(config)# hostname Router1 Router1(config)#步骤 2. 配置MOTD 标语：Router1(config)# banner motd %Enter TEXT message.End with the character ‘%’ *** *** % Router1(config)#1步骤3：配置特权执行口令。

将特权执行口令设置为class：Router1(config)# enable secret classRouter1(config)#步骤4：配置控制台口令：将控制台访问口令设置为cisco：Router1(config)# line console 0Router1(config-line)# password ciscoRouter1(config-line)# login步骤5：配置虚拟线路口令。

将虚拟线路访问口令设置为cisco：Router1(config-line)# line vty 0 4Router1(config-line)# password ciscoRouter1(config-line)# loginRouter1(config-line)# exitRouter1(config)#步骤6：配置路由器的fa0/0 接口：Router1(config)# interface fa0/0Router1(config-if)# description Connection to PC1 with crossover cable Router1(config-if)# ip address 198.168.1.1 255.255.255.0Router1(config-if)# no shutdownRouter1(config-if)# exitRouter1(config)#步骤7：配置路由器的s2/0 接口：Router1(config)# interface s2/0Router1(config-if)# description Connection to Router1 with DCE serial line Router1(config-if)# ip address 198.168.10.1 255.255.255.0Router1(config-if)# no shutdownRouter1(config-if)# exitRouter1(config)#步骤8：配置路由器Router2和Router3：依照以上Router1的配置注：路由器之间连接①串口（须在路由器的DCE端口设置时钟）；②以太网设置路由器1（Router1）的s2/0端口（DCE线连接）设置路由器1（Router1）的s2/0端口时钟：Router1(config)# interface s2/0Router1(config-if)# clock rate 12002Router1(config-if)# exit Router1(config)#设置路由器2（Router2）的s3/0端口（DCE线连接）设置路由器2（Router2）的s3/0端口时钟：Router2(config)# interface s3/0Router2(config-if)# clock rate 1200 Router2(config-if)# exit Router2(config)#缺省路由和静态路由试验知识点静态路由静态路由是指由网络管理员手工配置的路由信息。
