多區域ospf配置

多區域ospf的配置

 

 

◆RA的配置是

     int loopback 0
     ip add 192.168.64.1 255.255.255.0
     no shut
     exit
     int f1/0
     ip add 192.168.1.1 255.255.255.0
     no shut
     exit
     router ospf 1
     network 192.168.64.1 0.0.0.0 area 1
     network 192.168.1.1 0.0.0.0 area 0
◆RB的配置是

     int loopback 0
     ip add 192.168.3.1 255.255.255.0
     no shut
     exit
     int f1/0
     ip add 192.168.1.3 255.255.255.0
     no shut
     exit
     int s0/0
     ip add 192.168.224.1 255.255.255.252
     no shut
     router ospf 1
     network 192.168.1.3 0.0.0.0 area 0
     network 192.168.224.1 0.0.0.0 area 51
     network 192.168.3.1 0.0.0.0 area 0

◆RC的配置是
     int s0/1
     clock rate 128000
     ip add 192.168.224.2 255.255.255.252
     no shut
     router ospf 1
     network 192.168.224.2 0.0.0.0 area 51
      之後都可以ping通

◆在RB上   show iproute則是

    O IA 192.168.1.0/24 [110/782] via 192.168.224.1, 00:02:16,    srial0/0
     192.168.3.0/32 is subnetted, 1 subnets
O IA    192.168.3.1 [110/782] via 192.168.224.1, 00:02:16, Serial0/0
     192.168.64.0/32 is subnetted, 1 subnets
O IA    192.168.64.1 [110/783] via 192.168.224.1, 00:02:16, Serial0/0
     192.168.224.0/30 is subnetted, 1 subnets
C       192.168.224.0 is directly connected, Serial0/0
◆在RB和RC上

router ospf  1

area 51 stub

則出現的效果是

show ip route

O IA 192.168.1.0/24 [110/782] via 192.168.224.1, 00:00:02, Serial0/0
     192.168.3.0/32 is subnetted, 1 subnets
O IA    192.168.3.1 [110/782] via 192.168.224.1, 00:00:02, Serial0/0
     192.168.64.0/32 is subnetted, 1 subnets
O IA    192.168.64.1 [110/783] via 192.168.224.1, 00:00:02, Serial0/0
     192.168.224.0/30 is subnetted, 1 subnets
C       192.168.224.0 is directly connected, Serial0/0
O*IA 0.0.0.0/0 [110/782] via 192.168.224.1, 00:00:02, Serial0/0
◆在RB上配置

router ospf  1

area   51  stub   no-summary

則show ip route的結果是

C       192.168.224.0 is directly connected, Serial0/0
O*IA 0.0.0.0/0 [110/782] via 192.168.224.1, 00:00:02, Serial0/0

完成.
