思科路由器如何配置DHCP实例

思科路由器如何配置DHCP实例在一个局域网中，我们可以使用一个DHCP服务器来管理网络中的IP地址，这样会轻松很多的，也不需要担心IP地址冲突的问题了。

下面是店铺收集整理的思科路由器如何配置DHCP实例，希望对大家有帮助~~思科路由器如何配置DHCP实例客户需求：1.同时为多个VLAN的客户机分配地址2.VLAN内有部分地址采用手工分配的方式3.为客户指定网关、Wins服务器等4.VLAN 2的地址租用有效期限为1天,其它为3天5.按MAC地址为特定用户分配指定的IP地址最终配置如下：ip dhcp excluded-address 10.1.1.1 10.1.1.19 //排除的地址范围，不用于动态地址分配的地址ip dhcp excluded-address 10.1.1.240 10.1.1.254ip dhcp excluded-address 10.1.2.1 10.1.2.19!ip dhcp pool global //global是pool name地址池的名字，由用户指定，随便写不过一定写的通俗最起码自己要能看懂network 10.1.0.0 255.255.0.0 //动态分配的地址段(将要分配给用户的地址)dns-server 10.1.1.1 10.1.1.2 //为客户机配置dns服务器netbios-name-server 10.1.1.5 10.1.1.6 //为客户机配置wins服务器(这个根据情况设置，一般不需要)netbios-node-type h-node //为客户机配置节点模式(影响名称解释的顺利,如h-node=先通过wins服务器解释)lease 3 //地址租用期限: 3天ip dhcp pool vlan1network 10.1.1.0 255.255.255.0 //本pool是global的子pool, 将从global pool继承domain-name 等optiondefault-router 10.1.1.100 10.1.1.101 //为客户机配置默认网关!ip dhcp pool vlan2 //为另一VLAN配置的poolnetwork 10.1.2.0 255.255.255.0default-router 10.1.2.100 10.1.2.101lease 1!ip dhcp pool vlan1_liangwei //总是为MAC地址为010050.bade.6384的机器分配10.1.1.21地址host 10.1.1.21255.255.255.0client-identifier 010050.bade.6384 //client-identifier=01加上客户机网卡地址!ip dhcp pool vlan1_liangwei5host 10.1.1.50 255.255.255.0client-identifier 010010.3ab1.eac8相关的DHCP调试命令：no service dhcp //停止DHCP服务[默认为启用DHCP服务]sh ip dhcp binding //显示地址分配情况show ip dhcp conflict //显示地址冲突情况debug ip dhcp server {events | packets | linkage} //观察DHCP服务器工作情况如果DHCP客户机分配不到IP地址，常见的原因有两个。

Cisco基于策略路由的配置实例

问题描述您可以定义自己的规则来进行数据包的路由而不仅仅由目的地地址所决定。

在这里您可以学到怎么使用基于策略路由的办法来解决这一问题。

在具体的应用中，基于策略的路由有：☆基于源IP地址的策略路由☆基于数据包大小的策略路由☆基于应用的策略路由☆通过缺省路由平衡负载这里，讲述了第一种情况的路由策略。

举例在这个例子中，防火墙的作用是：把10.0.0.0/8内部网地址翻译成可路由的172.16 .255.0/24子网地址。

下面的防火墙配置是为了完整性而加进去的，它不是策略路由配置所必需的。

在这里的防火墙可以被其它类似的产品代替，如PIX或其它类似防火墙设备。

这里的防火墙的配置如下：!ip nat pool net-10 172.16.255.1 172.16.255.254 prefix-length 24ip nat inside source list 1 pool net-10!interface Ethernet0ip address 172.16.20.2 255.255.255.0ip nat outside!interface Ethernet1ip address 172.16.39.2 255.255.255.0ip nat inside!router eigrp 1redistribute staticnetwork 172.16.0.0default-metric 10000 100 255 1 1500!ip route 172.16.255.0 255.255.255.0 Null0access-list 1 permit 10.0.0.0 0.255.255.255!end在我们的例子中，Cisco WAN路由器上运行策略路由来保证从10.0.0.0/8网络来的P数据包被发送到防火墙去。

配置中定义了两条net-10策略规则。

第一条策略就定义了从10.0.0.0/8网络来的IP数据包被发送到防火墙去（我们很快会看到这里的配置有问题）。

Cisco路由器静态、动态路由配置

Cisco路由器静态、动态路由配置2010-07-22 20:31Cisco路由器静态、动态路由配置本文介绍Cisco路由器静态、动态路由配置，动态路由协议这里只介绍RIP、EIGRP、OSPF三种。

下面是网络拓扑图：如上图网络拓扑，配置路由协议使其网络连通（PC0和PC1互通）。

一、配置静态路由1．配置IP地址信息台式机的IP地址配置很简单，我这里不用多说，PC0 IP：10.3.0.2 NETMASK:255.255.255.0 PC1 IP:192.16.3.2 NETMASK:255.255.255.0 。

下面配置router0下面配置router1这里我们来试试PC0和PC1互通性PC0 ping PC1如图所示：这里我们看到PC0和PC1并不能相通。

PC1 ping PC0如图所示：这里我们看到PC1和PC0也并不能相通。

2.配置静态路由协议Router（config）#ip route 192.16.3.0 255.255.255.0 172.16.2.2 R1（config）#ip route 10.3.0.0 255.255.255.0 172.16.2.1 下面我们再来试试PC0和PC1互通性PC0 ping PC1如图所示：这里我们看到PC0和PC1能相通，我们配置的静态路由协议起作用了。

PC1 ping PC0如图所示：这里我们看到PC1和PC0能相通，我们配置的静态路由协议也起作用了。

二、 RIP路由协议的配置1. 配置IP地址信息配置IP地址信息见上面配置静态路由中配置IP地址信息，我这里不多说。

这里配置了ip地址以后如静态路由中一样，PC0和PC1不能相通。

2. 配置rip路由协议配置router0Router(config)#router ripRouter(config-router)#version 2Router(config-router)#network 10.3.0.0Router(config-router)#network 172.16.2.0配置router1R1(config)#router ripR1(config-router)#version 2R1(config-router)#network 192.16.3.0R1(config-router)#network 172.16.2.03. 查看rip路由信息查看router0查看router1这里我们可以看到R开头的路由信息即是通过rip协议得到的路由信息。

思科路由器配置命令详解及实例

思科路由器配置命令详解及实例思科路由器配置命令详解及实例一、路由器基本配置1.1 登录路由器为了配置和管理思科路由器，您需要登录到路由器的控制台或通过远程登录方式。

使用以下命令登录路由器，并进行必要的身份验证：```Router> enableRouterconfigure terminalEnter configuration commands, one per line： End with TL/Z：Router(config)hostname [路由器名称]Router(config)enable secret [密码]Router(config)line console 0Router(config-line)password [密码]Router(config-line)logging synchronousRouter(config-line)exitRouter(config)line vty 0 4Router(config-line)password [密码]Router(config-line)logging synchronous```1.2 配置接口接下来，您需要配置路由器的接口，以便与其他网络设备进行通信。

使用以下命令配置接口：```Router(config)interface [接口类型] [接口编号]Router(config-if)ip address [IP地址] [子网掩码]Router(config-if)no shutdownRouter(config-if)exit```二、路由配置2.1 静态路由静态路由是手动配置的路由项，将特定的网络目的地与下一跳路由器关联起来。

以下是配置静态路由的示例命令：```Router(config)ip route [目的网络] [子网掩码] [下一跳地址]```2.2 动态路由动态路由是通过路由协议动态学习并自动更新的路由项。

思科路由器SSH配置案例

思科路由器SSH配置案例思科路由器SSH配置案例SSH 为建立在应用层基础上的'安全协议。

SSH 是目前较可靠，专为远程登录会话和其他网络服务提供安全性的协议。

利用 SSH 协议可以有效防止远程管理过程中的信息泄露问题。

下面是思科路由器SSH 配置案例，希望对你有帮助！1. 配置hostname和ipdomain-nameRouter#configure terminalRouter(config)#hostname R2 //配置ssh的时候路由器的名字不能为routerR2(config)#ip domain-name //配置SSH必需R2(config)#username best password best1或 username best privilege 15 password 7 best1注：添加一个用户：best，口令：best1R2(config)#line vty 0 4R2(config-line)#transport input ssh //只允许用SSH登录(注意：禁止telnet和从交换引擎session!)2. 配置SSH服务：R2(config)#crypto key generate rsaThe name for the keys will be: 注：SSH的关键字名就是hostname + . +ipdomain-nameChoose the size of the key modulus in the range of 360 to 2048 for yourGeneral Purpose Keys. Choosing a key modulus greater than 512 may takea few minutsHow many bits in the modulus [512]: 注：选择加密位数，cisco推荐使用1024Generating RSA keys ...[OK]用命令show ip ssh也能看到：SSH Enabled - version 1.5Authentication timeout: 120 secs; Authentication retries:现在SSH服务已经启动，如果需要停止SSH服务，用以下命令：R2(config)#crypto key zeroize rsa3.设置SSH参数配置好了SSH之后，通过show run命令我们看到SSH默认的参数：超时限定为120秒，认证重试次数为3次，可以通过下面命令进行修改：R2(config)#ip ssh {[time-out seconds]} │ [authentication-retries interger]}如果要把超时限定改为180秒，则应该用：R2(config)# ip ssh time-out 180如果要把重试次数改成5次，则应该用：R2(config)# ip ssh authentication-retries这样，SSH已经在路由器上配置成功了，就能够通过SSH进行安全登录了。

实验三 Cisco路由器的基本配置

实验三 Cisco路由器的基本配置（验证性）（2学时）一、实验目的1.掌握Cisco路由器的基本配置命令2.熟悉Cisco路由器的配置环境二、实验内容（一）路由器的工作模式在命令行状态下，主要有以下几种工作模式：1.一般用户模式（UserEXEC）用户模式用于查看路由器的基本信息。

在用户模式下，只能够运行少数的命令，且不能对路由器进行配置。

从配置端口进入路由器时，首先要进入一般用户模式，一般用户模式下默认的路由器提示符为：Router>如果配置了路由器的名字，则提示符为：路由器的名字>用logout命令退出。

2.特权模式在默认状态下，特权模式可以使用比一般用户模式下多得多的命令。

特权模式用于查看路由器的各种状态，绝大多数命令用于测试网络、检查系统等，但是不能对端口及网络协议进行配置。

路由器未做任何配置时，输入enable命令即可由一般用户模式进入特权模式。

如果配置了口令，则需要输入口令。

默认的特权模式的提示符为：Router#如果配置了路由器的名字，则提示符为：路由器的名字#退出方法：用exit或disable命令退到userEXEC模式。

3.全局配置模式（GobalConfiguration）全局配置模式中可以配置一些全局性的参数。

要进入全局配置模式，必须首先进入特权模式。

在进入配置模式前，必须指定是通过终端、NVRAM或是网络服务器进行配置。

如果通过终端进行配置，输入config terminal命令，进入全局配置模式。

全局配置模式的提示符为：Router（config）#如果配置了路由器的名字，则提示符为：路由器的名字（config）#退出方法：可使用exit或end或Ctrl+Z命令退到特权模式4.全局配置模式下的配置子模式在全局配置模式下可进入各种配置子模式①端口配置模式进入方式：在全局配置模式下，用interface命令进入具体的端口Router（config）#interface 端口的类型端口号提示符：Router（config-if）#②子端口配置模式进入方式：在端口配置模式下用interface命令进入指定的子端口Router（config-if）#interface端口的类型端口号.子端口号提示符：Router（config-subif）#③路由配置模式进入方式：在全局配置模式下，用“router 具体的协议名”命令指定具体的路由协议。

Cisco路由器QoS配置实例详解

Cisco路由器QoS配置实例详解Cisco路由器QoS配置实例详解1、介绍本文档旨在详细介绍如何在Cisco路由器上配置QoS （Quality of Service）以优化网络性能和资源分配。

通过正确配置QoS，可以提供更好的网络服务质量，确保重要的数据流能够得到优先处理，从而提高网络整体性能。

2、QoS的基本概念在开始配置QoS之前，了解以下几个基本概念是很重要的： - 带宽：指网络在一定时间内能够传输的数据量，通常以每秒传输的比特数（bps）来表示。

- 延迟：指数据在网络中传输所需的时间延迟。

- 丢包率：指在数据传输过程中丢失的数据包的百分比。

- 重传：当数据包丢失时，发送方会重新发送相同的数据包。

- 流量控制：通过限制数据传输的速度，以避免网络拥塞。

3、QoS的常见策略针对不同类型的网络流量，可以使用多种QoS策略来优化性能：- Traffic Shaping：通过限制数据传输速率来平滑网络流量，避免拥塞。

- Traffic Policing：对流量施加限制，超出限制的流量将被丢弃或重标记。

- Priority Queuing：给重要数据流分配高优先级，确保其能够得到及时处理。

- Class-Based Queuing：根据数据流的类别分配带宽，优先处理重要的数据流。

- Weighted Fr Queuing：根据流量的重要性将带宽公平分配给不同的数据流。

- Low Latency Queuing：通过消除队列延迟来提供低延迟的服务。

4、配置QoS的步骤在Cisco路由器上配置QoS通常需要以下步骤：4.1 创建访问列表：用于标识要进行QoS处理的流量。

4.2 创建类别地图：将访问列表与QoS策略关联起来。

4.3 配置QoS策略：根据需求选择合适的QoS策略，并应用于特定的接口。

4.4 验证QoS配置：使用适当的测试工具验证配置是否生效，并对网络性能进行评估。

5、示例配置以下是一个示例配置，用于说明如何在Cisco路由器上实现基于端口的优先级排队（Port-Based Priority Queuing）： ```interface FastEthernet0/0priority-queue out```通过这个配置，接口FastEthernet0/0上的数据流将被赋予最高优先级，确保其能够得到及时处理。

思科路由器静态路由配置实验案例详解

思科路由器静态路由配置实验案例详解本⽂实例讲述了思科路由器静态路由配置实验。

分享给⼤家供⼤家参考，具体如下：实验⼋　路由器静态路由配置⼀、实验⽬标1. 掌握静态路由的配置⽅法和技巧；2. 掌握通过静态路由⽅式实现⽹络的连通性；3. 熟悉⼴域⽹线缆的链接⽅式；⼆、实验背景学校有新旧两个校区，每个校区是⼀个独⽴的局域⽹，为了使新旧校区能够正常相互通讯，共享资源。

每个校区出⼝利⽤⼀台路由器进⾏连接，两台路由器间学校申请了⼀条2M的DDN专线进⾏相连，要求做适当配置实现两个校区的正常相互访问。

三、技术原理1. 路由器属于⽹络层设备，能够根据IP包头的信息，选择⼀条最佳路径，将数据包转发出去。

实现不同⽹段的主机之间的互相访问。

路由器是根据路由表进⾏选路和转发的。

⽽路由表⾥就是由⼀条条路由信息组成。

2. ⽣成路由表主要有两种⽅法：⼿⼯配置和动态配置，即静态路由协议配置和动态路由协议配置。

3. 静态路由是指有⽹络管理员⼿⼯配置的路由信息。

4. 静态路由除了具有简单、⾼效、可靠的优点外，它的另⼀个好处是⽹络安全保密性⾼。

5. 缺省路由可以看做是静态路由的⼀种特殊情况。

当数据在查找路由表时，没有找到和⽬标相匹配的路由表项时，为数据指定路由。

四、实验步骤新建packet tracer拓扑图（1）在路由器R1、R2上配置接⼝的IP地址和R1串⼝上的时钟频率；（2）查看路由器⽣成的直连路由；（3）在路由器R1、R2上配置静态路由；（4）验证R1、R2上的静态路由配置；（5）将PC1、PC2主机默认⽹关分别设置为路由器接⼝fa 1/0的IP地址；（6）PC1、PC2主机之间可以相互通信；五、实验设备 pc 2台；Router-PT可扩展路由 2台（Switch_2811⽆V.35线接⼝）；Switch_2960 2台；DCE 串⼝线；直连线；交叉线六、实验拓扑图七、实验命令PC1IP: 192.168.1.2Submask: 255.255.255.0Gateway: 192.168.1.1PC2IP: 192.168.2.2Submask: 255.255.255.0Gateway: 192.168.2.1R1enconf thostname R1int fa 1/0no shutip address 192.168.1.1 255.255.255.0exitint serial 2/0no shutip address 192.168.3.1 255.255.255.0clock rate 64000（必须配置时钟才可通信）endR2enconf thostname R2int fa 1/0no shutip address 192.168.2.1 255.255.255.0exitint serial 2/0ip address 192.168.3.2 255.255.255.0no shutendR1enconf tip route 192.168.2.0 255.255.255.0 192.168.3.2endshow ip routeR2enconf tip route 192.168.1.0 255.255.255.0 192.168.3.1endshow ip route⼋、实验结果配置PC0、PC1的IP地址：配置R1，R2接⼝的IP 地址和R1串⼝上的时钟频率: 在路由器R1、R2上配置静态路由,验证R1、R2上的静态路由配置 PC0 ping PC1：。
