拓扑图:

配置代码: R1 enable config terminal host r1 no ip domain-lookup int g0/0 ip address 192.168.1.1 255.255.255.0 no shut exit router ospf 100 !进程号,1-65535中任意数,且这个是路由器本地进程号,即其它路由器也可以设置一样的进程号 !OSPF路由协议的进程号为100,一个路由器上可启用多个OSPF进程,以进程号作为区别标志 network 192.168.1.0 0.0.0.255 area 1 router-id 192.168.1.1 !这个路由器有多个接口,谁代表本区域跟别的交换链路状态数据报呢?就是路由id是谁呢?指定路由id,不指定也会进行选举(优先级一样时,谁的ip地址大,就做) exit R2 enable config terminal host r2 no ip domain-lookup int g0/0 ip address 192.168.1.2 255.255.255.0 no shut exit int g0/1 ip address 192.168.2.1 255.255.255.0 no shut exit router ospf 100 log-adjacency-changes !当一个OSPF域的邻接关系改变时,用日志记录 network 192.168.1.0 0.0.0.255 area 1 network 192.168.2.0 0.0.0.255 area 0 router-id 192.168.2.1 !强制指定router-id为192.168.2.1。router-id(RID)的作用是在一个OSPF域(area)的路由器群中作为选举DR(指定路由器)及BDR(备份指定路由器)的重要指标,当各个路由器的优先级(priority)相同时,RID最高者为DR。注:在一个OSPF域内的路由器交换OSPF路由信息时,不是两两交互的,而是由DR收集并发布 exit R3 enable config terminal host r3 no ip domain-lookup !下面设置接口的IP参数 int g0/0 ip address 192.168.2.2 255.255.255.0 no shut exit int g0/1 ip address 192.168.3.1 255.255.255.0 no shut exit int loopback 0 !环回口,一般常用环回口来做router-id ip address 3.3.3.3 255.255.255.255 no shut exit router ospf 100 network 192.168.2.0 0.0.0.255 area 0 network 192.168.3.0 0.0.0.255 area 2 router-id 3.3.3.3 !一般常用环回口来做router-id !area 2 virtual-link 4.4.4.4 exit R4 enable config terminal host r4 no ip domain-lookup int g0/0 ip address 192.168.3.2 255.255.255.0 no shut exit int g0/1 ip address 192.168.4.1 255.255.255.0 no shut exit int loopback 0 ip address 4.4.4.4 255.255.255.255 no shut exit router ospf 100 network 192.168.3.0 0.0.0.255 area 2 network 192.168.4.0 0.0.0.255 area 3 router-id 4.4.4.4 !area 2 virtual-link 3.3.3.3 exit R5 enable config terminal host r5 no ip domain-lookup int g0/0 ip address 192.168.4.2 255.255.255.0 no shut exit int loopback 0 ip address 5.5.5.5 255.255.255.255 no shut exit router ospf 100 network 192.168.4.0 0.0.0.255 area 3 router-id 5.5.5.5 Exit R1:
