思科设备参考：路由引入实验（思科）

技术简介

路由引入技术在网络通信中起着重要的作用，能够实现不同路由协议之间的路由传递，并在路由引入时部署路由控制，实现路径或策略的控制

        

实验目的

不同的路由协议之间互相学习到对方的路由信息，并连通（Import注入）

                

基础配置

Router1

[Huawei]undo info-center enable 
[Huawei]int LoopBack 1
[Huawei-LoopBack1]ip address 1.1.1.1 32
[Huawei-LoopBack1]quit
[Huawei]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.10.1 24
[Huawei-Ethernet0/0/0]undo shutdown
[Huawei-Ethernet0/0/0]quit
[Huawei]ospf 4 router-id 1.1.1.1
[Huawei-ospf-4]area 0
[Huawei-ospf-4-area-0.0.0.0]network 1.1.1.1 0.0.0.0
[Huawei-ospf-4-area-0.0.0.0]network 192.168.10.0 0.0.0.255

Router2

[Huawei]undo info-center enable 
[Huawei]int LoopBack 1
[Huawei-LoopBack1]ip address 2.2.2.2 32
[Huawei-LoopBack1]quit
[Huawei]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.10.2 24
[Huawei-Ethernet0/0/0]undo shutdown
[Huawei-Ethernet0/0/0]quit
[Huawei]int e0/0/1
[Huawei-Ethernet0/0/1]ip address 192.168.20.1 24
[Huawei-Ethernet0/0/1]undo shutdown
[Huawei-Ethernet0/0/1]quit
[Huawei]ospf 4 router-id 2.2.2.2 
[Huawei-ospf-4]area 0
[Huawei-ospf-4-area-0.0.0.0]network 2.2.2.2 0.0.0.0
[Huawei-ospf-4-area-0.0.0.0]network 192.168.10.0 0.0.0.255
[Huawei]rip 4
[Huawei-rip-4]version 2
[Huawei-rip-4]network 2.0.0.0
[Huawei-rip-4]network 192.168.20.0

Router3

[Huawei]undo info-center enable 
[Huawei]int LoopBack 1
[Huawei-LoopBack1]ip address 3.3.3.3 32
[Huawei-LoopBack1]quit
[Huawei]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.20.2 24
[Huawei-Ethernet0/0/0]undo shutdown
[Huawei-Ethernet0/0/0]quit
[Huawei]int e0/0/1
[Huawei-Ethernet0/0/1]ip address 192.168.30.1 24
[Huawei-Ethernet0/0/1]undo shutdown
[Huawei-Ethernet0/0/1]quit
[Huawei]rip 4
[Huawei-rip-4]version 2
[Huawei-rip-4]network 3.0.0.0
[Huawei-rip-4]network 192.168.20.0

测试

此时，基础配置已经完成，两个协议内部都可以学习到本协议的路由信息，并连通。但协议与协议之间的路由学习还需要配置路由引入

                

配置引入

Router2（边界路由器）

[Huawei]ospf 4 router-id 2.2.2.2
[Huawei-ospf-4]import-route rip 4
[Huawei-ospf-4]quit
[Huawei]rip 4
[Huawei-rip-4]import-route ospf 4

测试

        

路由引入可能会出现的问题

问题：次优路径问题和环路问题

解决方法：修改AD值或设置路由过滤
