5路由器的路由配置.

静态路由配置动态路由协议简介RIP和OSPF介绍课程目标学习完本课程，您应该能够：静态路由配置动态路由协议简介RIP和OSPF介绍目录静态路由由网络管理员在路由器上手工添加路由信息来实现路由动态路由根据网络结构或流量的变化，路由协议会自动调整路由信息来实现路由静态路由和动态路由静态路由配置注意：只有下一跳所属的的接口是点对点（PPP、HDLC）的接口时，才可以填写interface-name，否则必须填写nexthop-address。[H3C]iproute-staticip-address{mask|masklen}{interface-typeinterface-name|nexthop-address}[preferencevalue][reject|blackhole]静态路由的配置命令:例如：iproute-static129.1.0.01610.0.0.2iproute-static129.1.0.0255.255.0.010.0.0.2iproute-static129.1.0.016Serial0/0静态路由配置示例在路由器H3CA上配置：iproute-static129.1.0.0255.255.0.010.0.0.2iproute-static129.1.0.01610.0.0.2iproute-static129.1.0.016s0/0129.1.0.0/16E0/0H3CBS0/010.0.0.2H3CA10.0.0.1S0/0缺省路由配置示例在路由器H3CA上配置：iproute-static0.0.0.00.0.0.010.0.0.2Internet上大约99.99%的路由器上都存在一条缺省路由!缺省路由并不一定都是手工配置的静态路由，有时也可以由动态路由协议产生。H3CA10.0.0.1S0/010.0.0.2S0/0H3CBNetworkNPublicNetwork路由自环在路由器H3CA上配置：iproute-static20.0.0.0810.0.0.2“路由自环”对网络的危害极大，应尽量避免。在路由器H3CB上配置：iproute-static20.0.0.0810.0.0.1H3CA10.0.0.1S0/010.0.0.2S0/0H3CBNetworkNPublicNetwork静态路由配置动态路由协议简介RIP和OSPF介绍目录整个路由表路由器B路由器A路由器BS1/1整个路由表路由器A（二）每台路由器的链路状态数据库(一）网络的拓扑结构CABD123CABD123CABD123CABD123（四）每台路由器分别以自己为根节点计算最小生成树（三）由链路状态数据库得到的带权有向图CABD1235RTCRTD3215RTBRTA自治系统由同一机构管理，使用同一组选路策略的路由器的集合自治系统AS外部路由协议EGP100BGP内部路由协议IGPRIP，IGRP，OSPF自治系统AS200路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.00S0/0路由表路由器C路由器A路由器B路由器C路由表更新过程（一）S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.0S1/102.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/11路由表更新过程（二）S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.0S1/102.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02down路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/113S0/02.0.0.0S1/114.0.0.01.0.0.0S1/14S0/022方法一：定义最大路由权值S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.0S0/02.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/1116S0/02.0.0.0S1/114.0.0.01.0.0.0S1/116S0/0216方法二：水平分割S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.0S1/12.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02down方法三：毒性逆转S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.02.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02无限大S0/0方法四：抑制时间112234567891011112234567891011抑制时间后更新抑制时间后更新S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.03.0.0.01.0.0.0S1/12.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02down方法五：触发更新S0/0S1/1S0/0S1/1S0/0S1/12.0.0.04.0.0.01.0.0.0不可达3.0.0.01.0.0.0S1/12.0.0.00S0/0路由表路由器A2.0.0.0S0/003.0.0.00S1/1路由表路由器B3.0.0.0S1/104.0.0.0S0/0路由表路由器C路由器A路由器B路由器C03.0.0.0S0/011.0.0.04.0.0.0S1/111S0/02.0.0.0S1/114.0.0.01.0.0.0S1/12S0/02down1.0.0.0不可达1.0.0.0不可达静态路由配置动态路由协议简介RIP和OSPF介绍目录协议概述（一）RIP最多支持以跳数为衡量标准，最多15跳。RIP协议适用于中小型网络，有RIP-1和RIP-2。主机B2M56K2M2M主机A协议概述(二)TCPUDPIPPPPEtherRIP协议配置命令启动RIP协议，进入RIP协议配置视图[H3C]rip在指定的网络上使能RIP[H3C-rip-1]network{network-number}协议配置命令(续)配置报文的定点传送（不支持广播时）[H3C-rip-1]peerip-address指定接口版本（接口视图下）ripversion1ripversion2[broadcast|multicast]指定接口的工作状态（接口视图下）ripinputripoutput配置RIP-2路由聚合summary:11.1.1.1/24S0/0:1.1.1.1/24S0/0:1.1.1.2/24S0/1:2.1.1.2/24S0/0:2.1.1.1/24E1/0:13.1.1.1/24E1/0:12.1.1.1/24RTARTCRTB配置举例---配置命令（一）RTA:[RTA]rip[RTA-rip-1]network1.1.1.0[RTA-rip-1]network11.1.1.0[RTA-Ethernet1/0]ipaddress11.1.1.1255.255.255.0[RTA-Ethernet1/0]ripversion2broadcast[RTA-Serial0/0]link-protocolppp[RTA-Serial0/0]ipaddress1.1.1.1255.255.255.0[RTA-Serial0/0]ripversion2broadcast[RTA-Serial0/0]ripauthentication-modemd5rfc2453H3C配置举例---配置命令（二）RTB:[RTB]rip[RTB-rip-1]network1.1.1.0[R
