5.配置R1的OSPF
|
R1(config)#router ospf 1 //啟動OSPF程序 R1(config-router)#network 10.1.1.1 0.0.0.0 area 1 //使用0.0.0.0精確宣告網路 R1(config-router)#network 10.1.2.1 0.0.0.0 area 1 R1(config-router)#network 192.168.1.1 0.0.0.0 area 1 R1(config-router)#end |
6.配置R2的OSPF
|
R2(config)#router ospf 1 R2(config-router)#network 192.168.1.2 0.0.0.0 area 1 R2(config-router)#network 192.168.1.5 0.0.0.0 area 0 R2(config-router)#end |
7.配置R3的OSPF
|
R3(config)#router ospf 1 R3(config-router)#network 192.168.1.6 0.0.0.0 area 0 R3(config-router)#network 192.168.1.9 0.0.0.0 area 2 R3(config-router)#end |
8.配置R4的OSPF
|
R4(config)#router ospf 1 R4(config-router)#network 192.168.1.10 0.0.0.0 area 2 R4(config-router)#network 172.16.1.1 0.0.0.0 area 2 R4(config-router)#network 172.16.2.1 0.0.0.0 area 2 R4(config-router)#end |
9.在R2上檢視OSPF鄰居
|
R2#show ip ospf nei
Neighbor ID Pri State Dead Time Address Interface 192.168.1.9 0 FULL/ - 00:00:34 192.168.1.6 Serial1/1 10.1.2.1 0 FULL/ - 00:00:37 192.168.1.1 Serial1/0 |
10.檢視R1路由表，檢視區域間路由
|
R1#show ip route ospf 172.16.0.0/32 is subnetted, 2 subnets O IA 172.16.1.1 [110/193] via 192.168.1.2, 00:03:11, Serial1/0 //區域間路由用“O IA”表示
O IA 172.16.2.1 [110/193] via 192.168.1.2, 00:03:01, Serial1/0 192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks O 192.168.1.0/24 [110/128] via 192.168.1.2, 00:05:37, Serial1/0 |
11.檢視R1的OSPF鏈路狀態資料庫
|
R1#show ip ospf da
OSPF Router with ID (10.1.2.1) (Process ID 1)
Router Link States (Area 1) //型別1的LSA
Link ID ADV Router Age Seq# Checksum Link count 10.1.2.1 10.1.2.1 409 0x80000006 0x00E33E 3 192.168.1.5 192.168.1.5 400 0x80000005 0x007566 2
Summary Net Link States (Area 1) //型別3的LS—ABR產生
Link ID ADV Router Age Seq# Checksum 172.16.1.1 192.168.1.5 249 0x80000001 0x00CCC0 172.16.2.1 192.168.1.5 239 0x80000001 0x00C1CA 192.168.1.0 192.168.1.5 400 0x80000001 0x001E05 |
12.測試連通性
|
R1#ping 172.16.1.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/56/80 ms |
13.配置R2的區域間路由彙總
|
R2#config t Enter configuration commands, one per line. End with CNTL/Z. R2(config)#router ospf 1 R2(config-router)#area 1 range 10.1.0.0 255.255.0.0 R2(config-router)#end |
14.檢視R4的路由表
|
R4#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
172.16.0.0/24 is subnetted, 2 subnets C 172.16.1.0 is directly connected, Loopback0 C 172.16.2.0 is directly connected, Loopback1 10.0.0.0/16 is subnetted, 1 subnets O IA 10.1.0.0 [110/193] via 192.168.1.9, 00:00:28, Serial1/2 //出現彙總以後的路由
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks O IA 192.168.1.0/30 [110/256] via 192.168.1.9, 00:09:25, Serial1/2 C 192.168.1.0/24 is directly connected, Serial1/2 |
