实验环境
准备四台交换机分别命令为SW1、SW2、SW3、SW4；
需求如下：

#
SW4接口配置
#
interface Vlanif22
ip address 192.168.22.254 255.255.255.0
#
interface Ethernet0/0/0
portswitch
port link-type access

#
interface GigabitEthernet0/0/3
description to SW1_G0/0/3
ip address 1.1.1.13 255.255.255.252
#
PC接口配置
分别测试连通性
ospf配置 创建ospf 进程1 router-id 为loopback接口地址，区域为1，宣告所有直连地址，引入import-route， SW1
#
ospf 1 router-id 192.168.1.254
import-route direct
area 0.0.0.1
network 1.1.1.0 0.0.0.3
network 1.1.1.12 0.0.0.3
#
return
SW2
#
ospf 1 router-id 192.168.2.254
import-route direct
area 0.0.0.1
network 1.1.1.4 0.0.0.3
network 1.1.1.0 0.0.0.3
#
return
SW3
#
ospf 1 router-id 192.168.3.254
import-route direct
area 0.0.0.1
network 1.1.1.4 0.0.0.3
network 1.1.1.8 0.0.0.3
#
return
SW4
#

network 1.1.1.8 0.0.0.3
network 1.1.1.12 0.0.0.3
#
return
通过利用路由引入，将直连路由引入，简化命令配置
利用PC1做ping测试
