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。

图－１

本例中的配置练习采用思科模拟器 —— Cisco Packet Tracer 6.0，Route采用2621路由器实现。

  2. R2(config-if)#ip address 192.168.2.2 255.255.255.0
  3. R2(config-if)#no shutdown
  4. R2config-if)#exit
  5. R2(config)#interface fastEthernet 0/0
  6. R2(config-if)#ip address 192.168.3.254 255.255.255.0

  8. P - periodic downloaded static route
  9. Gateway of last resort is not set
  10. C 192.168.1.0/24 is directly connected, FastEthernet0/0
  11. C 192.168.2.0/24 is directly connected, FastEthernet0/1
  12. S 192.168.3.0/24 [1/0] via 192.168.2.2 //S表示静态路由

5）R2上添加静态路由

 
  1. R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1

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
  4. R3(config)#no ip route 192.168.2.0 255.255.255.0 192.168.3.1

12）R1、R3添加默认路由

 
  1. R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.2.2
  2. R3(config)#ip route 0.0.0.0 0.0.0.0 192.168.3.1

13）R1上查看路由表

 
  1. R1#show ip route
  2. Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
  3. D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
  4. N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
  5. E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
  6. i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
  7. * - candidate default, U - per-user static route, o - ODR
  8. P - periodic downloaded static route
  9. Gateway of last resort is 192.168.2.2 to network 0.0.0.0
  10. C 192.168.1.0/24 is directly connected, FastEthernet0/0
  11. C 192.168.2.0/24 is directly connected, FastEthernet0/1
  12. S* 0.0.0.0/0 [1/0] via 192.168.2.2 //默认路由

14）R3上查看路由表

 
  1. R3#show ip route
  2. Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
  3. D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
  4. N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
  5. E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
  6. i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
  7. * - candidate default, U - per-user static route, o - ODR
  8. P - periodic downloaded static route
  9. Gateway of last resort is 192.168.3.1 to network 0.0.0.0
  10. C 192.168.3.0/24 is directly connected, FastEthernet0/1
  11. C 192.168.4.0/24 is directly connected, FastEthernet0/0
  12. S* 0.0.0.0/0 [1/0] via 192.168.3.1 //默认路由
