实验目的：
1、掌握RIP与OSPF的重发布配置。
2、理解OSPF的E1与E2类型的路由。
实验拓扑图：
实验步骤及要求：
1、配置各台路由器的IP地址，并且使用Ping命令确认各路由器的直连口的互通性。
2、配置R1与R2的OSPF路由协议和R2与R3的RIP路由协议。
3、查看R1、R2和R3的路由表：
|
R1#show ip route Gateway of last resort is not set 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks C 172.16.255.0/30 is directly connected, Serial1/1 C 172.16.1.0/24 is directly connected, Loopback0 C 172.16.2.0/24 is directly connected, Loopback1 R1# |
|
R2#show ip route Gateway of last resort is not set 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks C 172.16.255.0/30 is directly connected, Serial1/0 O 172.16.1.0/24 [110/65] via 172.16.255.1, 00:02:47, Serial1/0 O 172.16.2.0/24 [110/65] via 172.16.255.1, 00:02:47, Serial1/0 192.168.255.0/30 is subnetted, 1 subnets C 192.168.255.0 is directly connected, Serial1/1 R 192.168.1.0/24 [120/1] via 192.168.255.1, 00:00:10, Serial1/1 R 192.168.2.0/24 [120/1] via 192.168.255.1, 00:00:10, Serial1/1 R2# |
|
R3#show ip route Gateway of last resort is not set C 192.168.255.0/24 is directly connected, Serial1/0 C 192.168.1.0/24 is directly connected, Loopback0 C 192.168.2.0/24 is directly connected, Loopback1 R3# |
4、根据show ip route命令可以看出，只有R2路由才可以学习到整个网络的完整路由。是因为，R2路由处于OSPF与RIP网络的边界。其同时运行了两种不同的路由协议。
5、为了确保R1和R2能够学习到整个网络路由。在R2上配置路由重发布。配置如下：
|
R2(config)#router ospf 1 R2(config-router)#redistribute rip metric 200 subnets R2(config-router)#exit R2(config)#router rip R2(config-router)#redistribute ospf 1 metric 10 R2(config-router)#exit |
6、查看R1路由器和R3路由器的路由表：
|
R1#show ip router 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks C 172.16.255.0/30 is directly connected, Serial1/1 C 172.16.1.0/24 is directly connected, Loopback0 C 172.16.2.0/24 is directly connected, Loopback1 192.168.255.0/30 is subnetted, 1 subnets O E2 192.168.255.0 [110/200] via 172.16.255.2, 00:02:47, Serial1/1 O E2 192.168.1.0/24 [110/200] via 172.16.255.2, 00:02:53, Serial1/1 O E2 192.168.2.0/24 [110/200] via 172.16.255.2, 00:02:53, Serial1/1 R1# |
|
R3#show ip router R 172.16.0.0/16 [120/10] via 192.168.255.2, 00:00:24, Serial1/0 C 192.168.255.0/24 is directly connected, Serial1/0 C 192.168.1.0/24 is directly connected, Loopback0 C 192.168.2.0/24 is directly connected, Loopback1 R3# |
7、确认路由有效性：
|
R1#ping 192.168.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 112/137/144 ms R1# |
|
R3#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 = 120/148/192 ms R3# |
8、实验完成。
