10. 查看R1的鏈路狀態數據庫
|
R1#show ip ospf da OSPF Router with ID (1.1.1.1) (Process ID 1) Router Link States (Area 1) //LSA 1 Link ID ADV Router Age Seq# Checksum Link count 1.1.1.1 1.1.1.1 50 0x80000005 0x000878 4 2.2.2.2 2.2.2.2 51 0x80000001 0x006E4D 2 Summary Net Link States (Area 1) //LSA 3 Link ID ADV Router Age Seq# Checksum 192.168.1.4 2.2.2.2 52 0x80000001 0x00D8B0 Summary ASB Link States (Area 1) //LSA 4 Link ID ADV Router Age Seq# Checksum 3.3.3.3 2.2.2.2 52 0x80000001 0x0037B0 Type-5 AS External Link States //LSA 5 Link ID ADV Router Age Seq# Checksum Tag 172.16.1.0 3.3.3.3 285 0x80000002 0x001E67 0 172.16.2.0 3.3.3.3 285 0x80000002 0x001371 0 172.16.3.0 3.3.3.3 291 0x80000002 0x00087B 0 |
11. 查看R1的路由表
|
R1#show ip route ospf 172.16.0.0/24 is subnetted, 3 subnets O E2 172.16.1.0 [110/100] via 192.168.1.2, 00:02:51, Serial0/0 O E2 172.16.2.0 [110/100] via 192.168.1.2, 00:02:51, Serial0/0 O E2 172.16.3.0 [110/100] via 192.168.1.2, 00:02:51, Serial0/0 192.168.1.0/30 is subnetted, 2 subnets O IA 192.168.1.4 [110/128] via 192.168.1.2, 00:02:51, Serial0/0 |
O IA爲外部區域的路由，O E2爲重發布進來的路由。
12. 測試連通性

15. 查看R1的路由表
|
R1#show ip route ospf 172.16.0.0/22 is subnetted, 1 subnets O E2 172.16.0.0 [110/100] via 192.168.1.2, 00:03:11, Serial0/0 192.168.1.0/30 is subnetted, 2 subnets O IA 192.168.1.4 [110/128] via 192.168.1.2, 00:15:26, Serial0/0 |
16. 再次測試連通性

R1#ping 172.16.2.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.2.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 16/65/148 ms R1#ping 172.16.3.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.3.1, timeout is 2 seconds: !!!!!
