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
