多个路由器配置静态路由|多个路由器配置静态路由 简单

在路由器的配置中管理距离什么意思

管理距离
缩写：AD 管理距离是指一种路由协议的路由可信度。每一种路由协议按可靠性从高到低，依次分配一个信任等级，这个信任等级就叫管理距离。
对于两种不同的路由协议到一个目的地的路由信息，路由器首先根据管理距离决定相信哪一个协议。 AD值越低，则它的优先级越高。 一个管理距离是一个从0——255的整数值，0是最可信赖的，而255则意味着不会有业务量通过这个路由。 直连的AD=0, static 静态的AD=1,EIGRP的AD=90，IGRP的AD=100，OSPF的AD=110,RIP的AD=120.

四个路由器，每个路由器就要配三条静态路由ip，以此类推
N=路由器
n-1=每个路由器就要配n-1条静态路由ip
静态IP很好配
1 在各个接口上配置好ip ，然后到配置模式 ip route 网络地址 目的地址

例如在route10的机器上配置如下：
(这个叫网络地址)(这个叫目的地址，也叫下一跳)
Router(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2
Router(config)#ip route 192.168.4.0 255.255.255.0 192.168.3.1
Router(config)#ip route 192.168.5.0 255.255.255.0 192.168.4.2
Router(config)#end
Router#write
整个拓扑配置如下

  1. 配置静态路由

1 配置静态路由 1.1 问题
路由器可以将不同网段之间的网络连接到一起，当路由器接收到数据包后要查看数据包中的目标IP，再检查自己的路由表，如果路由表中有和目标IP相匹配的路由条目，路由器才能将数据包按照该路由条目所指定的端口转发出去，实现不同网络之间的通信，那么路由器中的路由表是如何实现的呢？配置了路由器接口IP并为UP状态路由表中自动生成直连路由，对于非直连的路由，需通过静态路由管理员手工添加或通过配置动态路自动学习。
  • 配置静态路由
  • 配置浮动静态路由
  • 配置缺省路由
1.2 方案
网络环境及IP地址规划，如图-1所示。

11）R1、R3取消静态路由
  1. R1(config)#no ip route 192.168.3.0 255.255.255.0 192.168.2.2
  2. R1(config)#no ip route 192.168.4.0 255.255.255.0 192.168.2.2
  3. R3(config)#no ip route 192.168.1.0 255.255.255.0 192.168.3.1
