一、任务目标

1、R5为ISP，其上只能配置IP地址；R4作为企业边界路由器

2、整个OSPF环境IP基于172.16.0.0/16划分；

3、所有设备均可以访问R5的环回

4、减少LSA的更新量，加快收敛，保障更新安全；

5、全网可达

二、配置ip地址

PC1：

IP：192.168.1.254

子网掩码：255.255.255.0

网关：192.168.1.1

PC2：

IP：192.168.2.254

子网掩码：255.255.255.0

网关：192.168.2.2

PC3：

IP：192.168.3.254

子网掩码：255.255.255.0

网关：192.168.3.3

PC4：

IP：192.168.4.254

子网掩码：255.255.255.0

网关：192.168.4.4
