先看命令：router eigrp
redistribute ospf 1 match external 2
我在R2上做了重分发，将RIP路由重分发进了OSPF域内，R1上出现了RIP域内的路由：
Gateway of last resort is not set
3.0.0.0/24 is subnetted, 1 subnets
O E2 3.3.3.0 [110/20] via 192.168.1.2, 00:32:51, Serial2/1
4.0.0.0/32 is subnetted, 1 subnets
O 4.4.4.4 [110/65] via 192.168.2.1, 00:50:22, Serial2/0
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.1.0/24 is directly connected, Serial2/1
L 192.168.1.1/32 is directly connected, Serial2/1
192.168.2.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.2.0/24 is directly connected, Serial2/0
L 192.168.2.2/32 is directly connected, Serial2/0
O E2 192.168.3.0/24 [110/20] via 192.168.1.2, 00:32:51, Serial2/1
R1#
然后通过一条串行线在R2的上方又做了一个EIGRP，R2的S2/3接口和R5的所有接口都宣告进了EIGRP 90.
最后我想在R2上做一个重分发，将OSPF域内的外部路由就是R1上打OE的那些路由给重分发进EIGRP 90当中，所以才用了redistribute ospf 1 match external 2 metric 1 1 1 1 1500 ，但是做完之后在R5的路由表上并没有出现这些OSPF域内的外部路由，请问这是怎么回事？
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.5.0/24 is directly connected, Loopback1
L 172.16.5.1/32 is directly connected, Loopback1
192.168.4.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.4.0/24 is directly connected, Serial2/3
L 192.168.4.2/32 is directly connected, Serial2/3

噢噢噢，大多数人在学习的初期都有你这种误解。我也曾经有过。R1上的OE2是从R2得到的，在R2上show ip ospf database的话，你可以看到LSA OE2，但是ADV Router是R2自身，而不是R1。AD是在比较通过不同路由协议学来的路由信息时使用的，但是在你这个结构里，在R2来看，3.3.3.3的来源只有一个，也就是RIP，所以没有办法比较。如果有第三者通过OSPF重分发了关于3.3.3.3的路由的话，R2应该会选择那个OE2。

楼主
那为什么同属于OSPF域的R1就会有，而在R2上就没有呢？难道和路由表的某些工作原理有关？
sorry，刚才我误解你的意思了。我的原意是要使用redistribute ospf 1 match这条命令，所以呢，我不重分发RIP。刚才重新弄了一下拓扑，将R5连接到了R1上，将R1上的OSPF外部路由重分发进了EIGRP，这样的话，从R5到R3去的路由就全部都有了。回程呢，先将OSPF路由重分发进了RIP，然后又将EIGRP路由重分发进了OSPF，所以一切都通了。谢谢大神。
爱死你了，老师，我要给你红包，感谢这么长时间以来你的帮助
有袁大头，行吗
