OSPF高级配置

路由重分发:

一.理解路由重分发:

1.一个单一IP路由协议是管理网络中IP路由的首选方案

2.Cisco ISO能执行多个路由协议,每一个路由协议和该路由协议所三分钟时时彩服务
的网络属于同一个自治系统

3.Cisco ISO使用路由重分发特性以交换不同协议创建的路由信息

二.路由重分发的考虑:

1.度量值

2.管理距离

三.重分发到OSPF域中路由的路径类型:


1.类型1的外部路径(type1 external path,E1)

2.类型2的外部路径(type2 external path,E2)

路由重分发配置

一.路由重分发配置命令:

Router(config-router)#redistribute protocol metric metric-value metric-type type-value subnets

二.OSPF与RIP重分发配置实例:

router rip

  redistribute ospf 1metric 10

router ospf 1

  redistribute rip metric 200 subnets
三.OSPF重分发静态路由配置实例:
router ospf 1

  redistribute static metric 100 subnets metric-type2
四.OSPF重分发默认路由配置实例:
router ospf 1

  network 192.168.0.0 0.0.0.255 area 0

  default-information originate metric 10 netric-type 1

ip route 0.0.0.0 0.0.0.0 10.0.1.1

OSPF高级配置实验:(GNS3中拓扑图如下)

大型三分钟时时彩公司
网络之——OSPF高级配置(实验)

实验环境准备:GNS3及与之相连的CRT

实验中需要用到的协议有:默认路由协议、静态路由协议、RIP协议、OSPF协议

打开GNS3后:
1.拖出六个路由器(每台路由器需要右键点击选择configure,在Slots中添加一个端口NM-1FE-TX,点击OK添加)
2.四台PC机
3.将R6的 图标改为cloud(这里作为电信运营商)

其中:
1.area1和area2都为ospf协议
2.R4到R5段为RIP协议
3.R3担任ABR的角色

第一步:根据拓扑图上的端口环境配置端口三分钟时时彩地址 :

第二步:进入四台客户机配置IP三分钟时时彩地址 和网关:

1客户机>ip 192.168.10.2 192.168.10.1
2客户机>ip 192.168.70.2 192.168.70.1
3客户机>ip 13.0.0.13 13.0.0.1
4客户机>ip 192.168.60.2 192.169.60.1

第三步:进行全网互通测试:

进入PC1

PC1>ping 192.168.70.2 -t(长ping测试)
PC1>ping 192.168.60.2 -t(长ping测试)
PC1>ping 13.0.0.13 -t(长ping测试)
结果如下图,达成全网互通,实验成功!
