拓扑图：
场景
你是公司的网络管理员。当前公司网络使用了RIPv2和OSPF协议。为了实现RIP区域设备与OSPF区域设备之间的互通。你需要配置路由的相互引入操作。配置时需要注意不同路由协议度量值定义的标准。
学习任务
步骤一.基本配置与IP编址
[Huawei]sysname R1
[R1]interface s1/0/0
[R1-Serial1/0/0]ip add 10.0.12.1 24
[R1-Serial1/0/0]desc this port connect to R2-S1/0/0
[R1-Serial1/0/0]interface g0/0/0
[R1-GigabitEthernet0/0/0]ip add 10.0.13.1 24
[R1-GigabitEthernet0/0/0]desc this port connect toR3-G0/0/0
[R1-GigabitEthernet0/0/0]interface loopback0
[R1-LoopBack0]ip add 10.0.1.1 24
[R1-LoopBack0]q
R2、R3、IP编址参照R1配置
步骤二.OSPF协议配置及验证
R1与R2之间运行OSPF，配置属于Area0.
[R1]ospf 1 rout
[R1]ospf 1 router-id 10.0.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]
[R2]ospf 1 router-id 10.0.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.0.2.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255
查看R1、R2的路由表、确认已通过OSPF学习其他网段的路由。
<R1>dis ip routing-table protocol ospf
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : OSPF
Destinations : 1 Routes :1
OSPF routing table status : <Active>
Destinations : 1 Routes : 1
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.0.2.2/32 OSPF 10 48 D 10.0.12.2 Serial1/0/0
OSPF routing table status : <Inactive>
Destinations : 0 Routes : 0
<R2>dis ip routing-table protocol ospf
<R2>
OSPF区域的网络都与R2直连，所以R2未通过OSPF学到额外的路由信息。
步骤三.RIPv2协议配置及验证
在R1上开启RIP协议进程，配置实用版本号为2.将10.0.0.0网段通告进RIP路由进程。
[R1]rip 1
[R1-rip-1]version 2
[R1-rip-1]network 10.0.0.0
在R3上开启RIP协议进程，配置实用版本号为2，将172.16.0.0和10.0.0.0两个网段通告进RIP路由进程。
[R3]rip 1
[R3-rip-1]version 2
[R3-rip-1]network 10.0.0.0
[R3-rip-1]network 172.16.0.0
查看R1和R3的路由表，确认路由器已经通过RIP学习到相应的路由。
[R1]dis ip routing-table protocol rip
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : RIP

10.0.12.0/24 RIP 100 1 D 10.0.13.1 GigabitEthernet0/0/0
RIP routing table status : <Inactive>
Destinations : 0 Routes : 0
步骤四.RIPv2和OSPF协议相互引入配置及验证
到目前为止，R2、R3未学到对方的路由信息，原因是他们不在同一种路由区域。在R1上将RIP学到的路由引入到OSPF路由表中。
[R1]ospf 1
[R1-ospf-1]impor
[R1-ospf-1]import-route rip 1 cost 100
在R1上执行将ospf路由引入到RIP路由域。
[R1]rip 1
[R1-rip-1]import-route ospf 1 cost 1
验证R1、R2、R3的路由表，确认学习到路由
[R1]display ip routing-table

255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
R1的路由表之前比较无变化，原因是R1同时处于OSPF和RIP路由区域，在引入路由之前就已经学习到了所有的路由信息。
确认R2、R3的路由表已经学习到如下路由。

此时R1、R2学到的路由是汇总路由172.16.0.0/22,而不是明细路由172.16.0.0/24等
理解路由相互引入的意义
掌握从OSPF向RIP注入路由的方法
掌握从RIP向OSPF注入路由的方法
拓扑图：
场景
你是公司的网络管理员。当前公司网络使用了RIPv2和OSPF协议。为了实现RIP区域设备与OSPF区域设备之间的互通。你需要配置路由的相互引入操作。配置时需要注意不同路由协议度量值定义的标准。
学习任务
步骤一.基本配置与IP编址
[Huawei]sysname R1
[R1]interface s1/0/0
[R1-Serial1/0/0]ip add 10.0.12.1 24
[R1-Serial1/0/0]desc this port connect to R2-S1/0/0
[R1-Serial1/0/0]interface g0/0/0
[R1-GigabitEthernet0/0/0]ip add 10.0.13.1 24
[R1-GigabitEthernet0/0/0]desc this port connect toR3-G0/0/0
[R1-GigabitEthernet0/0/0]interface loopback0
[R1-LoopBack0]ip add 10.0.1.1 24
[R1-LoopBack0]q
R2、R3、IP编址参照R1配置
步骤二.OSPF协议配置及验证
R1与R2之间运行OSPF，配置属于Area0.
[R1]ospf 1 rout
[R1]ospf 1 router-id 10.0.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]
[R2]ospf 1 router-id 10.0.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.0.2.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255
查看R1、R2的路由表、确认已通过OSPF学习其他网段的路由。
<R1>dis ip routing-table protocol ospf
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : OSPF
Destinations : 1 Routes :1
OSPF routing table status : <Active>
Destinations : 1 Routes : 1
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.0.2.2/32 OSPF 10 48 D 10.0.12.2 Serial1/0/0
OSPF routing table status : <Inactive>
Destinations : 0 Routes : 0
<R2>dis ip routing-table protocol ospf
<R2>
OSPF区域的网络都与R2直连，所以R2未通过OSPF学到额外的路由信息。
步骤三.RIPv2协议配置及验证
在R1上开启RIP协议进程，配置实用版本号为2.将10.0.0.0网段通告进RIP路由进程。
[R1]rip 1
[R1-rip-1]version 2
[R1-rip-1]network 10.0.0.0
在R3上开启RIP协议进程，配置实用版本号为2，将172.16.0.0和10.0.0.0两个网段通告进RIP路由进程。
[R3]rip 1
[R3-rip-1]version 2
[R3-rip-1]network 10.0.0.0
[R3-rip-1]network 172.16.0.0
查看R1和R3的路由表，确认路由器已经通过RIP学习到相应的路由。
[R1]dis ip routing-table protocol rip

RIP routing table status : <Inactive>
Destinations : 0 Routes : 0
步骤四.RIPv2和OSPF协议相互引入配置及验证
到目前为止，R2、R3未学到对方的路由信息，原因是他们不在同一种路由区域。在R1上将RIP学到的路由引入到OSPF路由表中。
[R1]ospf 1
[R1-ospf-1]impor
[R1-ospf-1]import-route rip 1 cost 100
在R1上执行将ospf路由引入到RIP路由域。
[R1]rip 1
[R1-rip-1]import-route ospf 1 cost 1
验证R1、R2、R3的路由表，确认学习到路由

255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
R1的路由表之前比较无变化，原因是R1同时处于OSPF和RIP路由区域，在引入路由之前就已经学习到了所有的路由信息。
确认R2、R3的路由表已经学习到如下路由。

测试网络连通性。在R2上使用扩展ping命令，定义数据包的源地址，测试到达地址10.0.3.3的连通性。
<R2>ping -a 10.0.2.2 10.0.3.3
PING10.0.3.3: 56 data bytes, press CTRL_C tobreak
Request time out

在R3的接口G0/0/0上配置RIP手动路由汇总。

验证R1、R2的路由表、比较与步骤三中显示的路由表的区别。

此时R1、R2学到的路由是汇总路由172.16.0.0/22,而不是明细路由172.16.0.0/24等
