Ospf路由重分部到rip
 
 
Route3为自制系统路由协议ASBR，通过Route0进行路由重分布，Route0、Route1、Route2为骨干区域area0.
网段划分：
Route0-route1 172.16.0.0/24
Route1-route2 172.16.1.0/24
Route0-route2 172.16.2.0/24
Route3-route0 10.0.0.0/24
Route0配置：
基本借口配置：
Int f0/0 ip add 172.16.0.1 255.255.255.0
         No shut(此命令在配置中只显示一次)
Int f0/1 ip add 10.0.0.2 255.255.255.0
Int f1/0 ip add 172.16.2.1 255.255.255.0
Ospf配置：
Conf)router ospf 100
Net 172.16.0.0 0.0.0.255 area 0
Net 172.16.2.0 0.0.0.255 area 0
Net 10.0.0.0 0.0.0.255 area 0
Route 1和Route 2配置类似，在此不再显示。
接下来配置Route 3 Rip路由器：
基本接口配置：
Int f0/0 ip add 192.168.0.1 255.255.255.0
Int f0/1 ip add 10.0.0.1 255.255.255.0
重分部Ospf配置：
Conf)router ospf 20
Net 172.16.0.0 0.0.0.255 area 0
Net 172.16.2.0 0.0.0.255 area 0
Redistribute rip subents
路由重分部到Rip：
Conf)route rip
Version 2
Net 10.0.0.0
Net 192.168.0.0
添加一条到ASBR路由器的默认路由：
Conf)ip route 0.0.0.0 0.0.0.0 10.0.0.0.2
