路由器ospf动态路由配置

技术原理:
Ospd开放式最短路径优先协议。是目前网络中应用最广泛的路由协议之一。属于内部网络路由协议。能够适应各种规模的网络环境,是典型的链路状态协议。Ospf路由协议通过向全网扩散本设备的链路状态信息,使网络中每台设备最终同步一个具有全网链路状态的数据库,然后路由器采用spf算法。以自己为根,计算到达网络的最短路径,最终形成全网路由信息。
实验步骤:
1.在本实验中的三层交换机上划分vlan10和vlan20,其中vlan10用于连接主机,vlan20用于连接R1.2.路由器之间通过v35电缆通过串口连接,DCE端连接在R1上,配置其时钟频率64000.3.主机和交换机通过直连线,主机与路由器通过交叉线连接。4.在S3560上配置ospf路由协议。5.在路由器R1、R2上配置ospf路由协议6.将pc1、pc2主机默认网关设置为与直连网络设备接口IP地址7.验证pc1、pc2主机之间可以互相通实验图:

S3650配置:

Enter configuration commands, one perline. End with CNTL/Z.
Switch(config)#host s3650

s3650(config-if)#exit
s3650(config)#int fa0/20
s3650(config-if)#switchport access vlan 20

R2(config-router)#exit
R2(config)#
测试:
从pc2 pingpc1.不通
在s3650上配置:
s3650#config t
Enter configuration commands, one perline. End with CNTL/Z.
s3650(config)#ip routing
s3650(config)#exit
s3650#
此时测试已通
