思科路由器配置教程
引言概述：在现代网络中，路由器是连接计算机网络的关键设备之一。
其中思科路由器是业界认可的品牌，并且广泛应用于企业和家庭网络中。
本文将详细介绍如何配置思科路由器，帮助读者了解和掌握路由器配置的基本知识和技巧。
正文内容：一、连接路由器1.检查硬件连接：确保所有线缆正确插入路由器和计算机的相应端口。
2.配置本地网络：通过计算机的网络设置，将本地IP地质和子网掩码设置为与路由器相同的网段。
二、路由器基本设置1.登录路由器：通过输入默认的IP地质（一般为192.168.1.1或192.168.0.1）在浏览器中访问路由器的登录页面，输入管理员用户名和密码。
2.修改管理员密码：为了增加路由器的安全性，第一次登录时应该修改管理员密码。
3.更新路由器固件：使用最新的路由器固件可以提供更好的性能和安全性。
4.配置时间和日期：确保路由器的时间和日期正确，这对于日志记录和网络安全非常重要。
三、WAN设置1.配置接入类型：根据网络服务提供商的要求，选择正确的接入类型，例如DHCP、静态IP等。
2.配置PPPoE连接：如果使用PPPoE方式拨号上网，需要输入提供商提供的用户名和密码进行配置。
3.配置动态DNS：如果需要使用动态DNS功能，可以在此处输入相应的信息。
四、LAN设置1.设置局域网IP地质：为路由器设置一个唯一的IP地质，在同一网段内没有重复的IP。
2.配置DHCP服务器：启用DHCP服务器功能，为连接到路由器的设备动态分配IP地质。
3.设置无线网络：为无线网络设置SSID和安全密码，并配置其他相关选项，如频段、通道等。
五、高级设置1.配置端口转发：如果需要将外部访问域名映射到内部服务器，可以在此处进行端口转发配置。
2.配置虚拟专用网络（VPN）：为用户提供远程访问网络的安全通道。
3.设置防火墙规则：根据网络需求设置适当的防火墙规则来保护网络安全。
4.配置质量服务（QoS）：可以通过设置QoS规则提高特定应用程序或设备的网络性能。

思科路由器配置基础
思科路由器配置基础思科路由器配置基础思科(Cisco)路由器是智能信息网络的基础，为当今要求最严格的网络服务，包括IP 通信、视频、客户关系管理、金融交易和其他实时应用提供了高可用性、全面的安全性、易管理性和先进的服务质量( QoS )。
下面店铺准备了思科路由器配置基础，欢迎大家参考!一、基本设置方式一般来说，可以用5种方式来设置路由器：1.Console口接终端或运行终端仿真软件的微机;2.AUX口接MODEM，通过电话线与远方的终端或运行终端仿真软件的微机相连;3.通过Ethernet上的TFTP服务器;4.通过Ethernet上的TELNET程序;5.通过Ethernet上的SNMP网管工作站。
但路由器的第一次设置必须通过第一种方式进行,此时终端的硬件设置如下:波特率：9600数据位：8停止位：1奇偶校验: 无二、命令状态1. router>路由器处于用户命令状态，这时用户可以看路由器的连接状态，访问其它网络和主机，但不能看到和更改路由器的设置内容。
2. router#在router>提示符下键入enable,路由器进入特权命令状态router#，这时不但可以执行所有的用户命令，还可以看到和更改路由器的设置内容。
3. router(config)#在router#提示符下键入configure terminal,出现提示符router(config)#，此时路由器处于全局设置状态，这时可以设置路由器的全局参数。
4. router(config-if)#; router(config-line)#; router(config-router)#;…路由器处于局部设置状态，这时可以设置路由器某个局部的参数。
5. >路由器处于RXBOOT状态，在开机后60秒内按ctrl-break可进入此状态，这时路由器不能完成正常的功能，只能进行软件升级和手工引导。
6. 设置对话状态这是一台新路由器开机时自动进入的状态，在特权命令状态使用SETUP命令也可进入此状态，这时可通过对话方式对路由器进行设置。

1)被动端口
passive interface 端口号
2)缺省路由
ip default 网络号/端口网络
3)静态路由
ip route 目标网络号 掩码 端口号

rl# show cdp neighbors 查看CDP邻居信息
rl(config-if)# ip add 10.0.0.1 255.0.0.0 进入相应的接口，配置相应的IP地址
rl# ping 10.0.0.2 使用ping命令查看邻居的连通性

思科交换机路由基本配置命令
思科交换机路由基本配置命令常用命令1.配置接口：interface {interface_type} {interface_number}2.配置IP地址：ip address {IP_address} {subnet_mask}3.配置默认网关：ip default-gateway {default_gateway_IP}4.开启接口：no shutdown5.配置路由协议：router {routing_protocol}6.配置路由器ID：router-id {router_ID}7.配置路由信息：network {network_address} {subnet_mask}8.配置静态路由：ip route {destination_network} {subnet_mask}{next-hop_IP}9.配置动态路由：router {routing_protocol} {network_address}10.保存配置：copy running-config startup-config注意：上述命令仅作为参考，具体配置应根据实际环境和设备型号进行调整。
下面是一些基本的 Cisco 交换机路由配置命令:1.配置 hostname: hostname <name>2.配置 IP 地址: interface <interface> 后进入接口模式，再输入 ipaddress <ip address> <subnet mask>3.配置默认路由: ip route 0.0.0.0 0.0.0.0 <next hop IP>4.启用路由协议: router <protocol> (例如: router rip)5.配置路由连接: network <network address> (例如: network192.168.1.0)6.查看路由表: show ip routeCisco 交换机路由配置步骤1.进入配置模式：configure terminal2.配置 IP 地址和子网掩码：interface [interface-name] ; ip address[ip-address] [subnet-mask]3.配置默认路由：ip route 0.0.0.0 0.0.0.0 [next-hop-IP-address]4.启用路由协议：router [protocol-name] (如：router ospf)5.配置路由协议参数： [protocol-name] [process-id] (如：ospf 1)6.配置路由连接：network [network-address] [wildcard-mask] area[area-id] (如：network 192.168.1.0 0.0.0.255 area 0)7.保存配置：copy running-config startup-config8.退出配置模式：exit。
