ripv2&ospf路由重发布
拓扑图
要求
如上拓扑图，左侧路由使用ospf协议，右侧使用ripv2协议，让网络全网互通。
1. 在各个路由器上配置网络ip
AR0
[Huawei-Serial0/0/0]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.1.1 255.255.255.0
[Huawei-Serial0/0/0]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.1.1 255.255.255.0
AR1
Enter system view, return user view with Ctrl+Z.
[Huawei]int s0/0/0
[Huawei-Serial0/0/0]ip address 192.168.2.2 255.255.255.0
Enter system view, return user view with Ctrl+Z.
[Huawei]int s0/0/0
[Huawei-Serial0/0/0]ip address 192.168.2.2 255.255.255.0
AR2
[Huawei]int s0/0/1
[Huawei-Serial0/0/1]ip address 192.168.3.2 255.255.255.0
[Huawei-Serial0/0/1]int s0/0/2
[Huawei-Serial0/0/2]ip address 192.168.4.1 255.255.255.0
AR3
[Huawei]int s0/0/2
[Huawei-Serial0/0/2]ip address 192.168.4.2 255.255.255.0
[Huawei-Serial0/0/2]int e0/0/0
[Huawei-Ethernet0/0/0]ip address 192.168.5.1 255.255.255.0
2.在客户机CLIENT配置IP
CLIENT0
IP : 192.168.1.2
掩码:255.255.255.0
网关：192.168.1.1
CLIENT1
IP :192.168.5.2
掩码：255.255.255.0
网关：192.168.5.1
3.在左区域路由器上配置ospf
AR0
在做的时候在实机上做的步骤和在虚拟机上做的步骤是不同的，可能是版本的不同，实机的步骤如下
[Huawei]int e0/0/0
[Huawei-Ethernet0/0/0]ospf enable area 0
[Huawei-Ethernet0/0/0]quit
[Huawei]int s0/0/0
[Huawei-Serial0/0/0]ospf enable area 0
[Huawei-Serial0/0/0]quit
因为现在是用虚拟机做的，所以以下全是虚拟机的步骤。
虚拟机步骤如下
[Huawei]ospf
[Huawei-ospf-1]area 0
[Huawei-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[Huawei-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255
AR1
[Huawei]ospf
[Huawei-ospf-1]area 0
[Huawei-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255
[Huawei-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255
AR2
[Huawei]ospf
[Huawei-ospf-1]area 0
[Huawei-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255
4.在右侧区域路由器配置ripv2
AR2
[Huawei]
[Huawei]int s0/0/2
[Huawei-Serial0/0/2]rip version 2
[Huawei]rip
[Huawei-rip-1]network 192.168.4.0
AR3
[Huawei]
[Huawei]int s0/0/2
[Huawei-Serial0/0/2]rip version 2
[Huawei-Serial0/0/2]int e0/0/0
[Huawei-Ethernet0/0/0]rip version 2
[Huawei-Ethernet0/0/0]quit
[Huawei]rip
[Huawei-rip-1]network 192.168.4.0
[Huawei-rip-1]network 192.168.5.0
5.在AR1上查看路由
[Huawei]dis ip rout
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
Destinations : 9 Routes : 9
Destination/Mask Proto Pre Cost Flags NextHop Interface
127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0
127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0
192.168.1.0/24 OSPF 10 1563 D 192.168.2.1 Serial0/0/0
192.168.2.0/24 Direct 0 0 D 192.168.2.2 Serial0/0/0
192.168.2.1/32 Direct 0 0 D 192.168.2.1 Serial0/0/0
192.168.2.2/32 Direct 0 0 D 127.0.0.1 Serial0/0/0
192.168.3.0/24 Direct 0 0 D 192.168.3.1 Serial0/0/1
192.168.3.1/32 Direct 0 0 D 127.0.0.1 Serial0/0/1
192.168.3.2/32 Direct 0 0 D 192.168.3.2 Serial0/0/1
可以看到学习到了1.0网段，但并没有学习到5.0与4.0的网段，我们可以在1.0
网段的主机ping 一下5.0网段的主机，看下结果
PC>ping 192.168.5.2
Ping 192.168.5.2: 32 data bytes, Press Ctrl_C to break
Request timeout!

6.要想在不同协议下相互学习到路由，需要进行路由重发布
现在我们要在路由器AR2上配置路由重发布
[Huawei]ospf
[Huawei-ospf-1]import-route rip
[Huawei]rip
[Huawei-rip-2]import-route ospf
现在可以在AR2上查看一下路由信息
[Huawei]dis ip rout
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
Destinations : 11 Routes : 11
Destination/Mask Proto Pre Cost Flags NextHop Interface
127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0
127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0
192.168.1.0/24 OSPF 10 1563 D 192.168.2.1 Serial0/0/0
192.168.2.0/24 Direct 0 0 D 192.168.2.2 Serial0/0/0
192.168.2.1/32 Direct 0 0 D 192.168.2.1 Serial0/0/0
192.168.2.2/32 Direct 0 0 D 127.0.0.1 Serial0/0/0
192.168.3.0/24 Direct 0 0 D 192.168.3.1 Serial0/0/1
192.168.3.1/32 Direct 0 0 D 127.0.0.1 Serial0/0/1
192.168.3.2/32 Direct 0 0 D 192.168.3.2 Serial0/0/1
192.168.4.0/24 O_ASE 150 1 D 192.168.3.2 Serial0/0/1
192.168.5.0/24 O_ASE 150 1 D 192.168.3.2 Serial0/0/1
可以看到已经都学习到4.0与5.0网段，现在可以使用1.0网段的主机ping 5.0网段的主机，测试连通性。
