通过以下思路实现R1 ping 通 R5
R5(config-if)#router ospf 110
R5(config-router)#router-id 5.5.5.5
R5(config-router)#network 202.106.45.0 0.0.0.255 area 2
R5(config-router)#network 5.5.5.5 0.0.0.0 area 2
R2#show ip ospf neighbor(查看ospf的状态)
Neighbor ID Pri State Dead Time Address Interface
1.1.1.1 1 FULL/BDR 00:00:37 202.106.12.1 FastEthernet0/0
R6上配置rip协议命令如下：
R6(config)#router rip
R6(config-router)#no auto-summary（关闭自动汇总）
R6(config-router)#network 11.0.0.0
R6(config-router)#network 11.11.11.0
R1上还需要运行RIP协议
R1(config)#router rip
R1(config-router)#ver 2
R1(config-router)#no auto-summary
R1(config-router)#network 11.0.0.0
R1#show ip route rip（查看rip协议）
11.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
R 11.11.11.11/32 [120/1] via 11.0.0.1, 00:00:12, FastEthernet0/0
R1上一个属于ospf域，一个属于rip域，将R1上的rip域引入ospf域，R2和R5还需要学R6上的rip
将R1上的rip引入ospf域
R1(config-router)#redistribute rip ?
metric Metric for redistributed routes
metric-type OSPF/IS-IS exterior metric type for redistributed routes
route-map Route map reference
subnets （子网） Consider subnets for redistribution into OSPF
tag Set tag for routes redistributed into OSPF
R1(config-router)#redistribute rip subnets（引入子网）
R2#show ip route
O E2 11.11.11.11/32 [110/20] via 202.106.12.1, 00:00:18, FastEthernet0/0
R1#show ip ospf database ?（6种LSA如下）
adv-router Advertising Router link states
asbr-summary ASBR summary link states
database-summary Summary of database
external External link states
network Network link states
nssa-external NSSA External link states
opaque-area Opaque Area link states
opaque-as Opaque AS link states
opaque-link Opaque Link-Local link states
router Router link states
self-originate Self-originated link states
summary Network summary link states
