网络拓扑

组网说明

1、Cloud1连接本地网络，AR路由器自动获取IP
2、LSW1交换机OSPF与路由器组网
3、LSW2交换机OSPF与LSW1交换机1组网
4、PC1和PC2分配各自网段IP

效果

1、PC1与PC2互通
2、PC1和PC可以联网外网

配置

路由器配置

只配置Area0连接，其它通过路由引入直连，路由器配置默认路由

#

 dns server 223.5.5.5
#
vlan batch 188
#
dhcp enable
#

LSW1配置

只配置Area0连接，其它通过路由引入直连。

#

  network 192.168.88.0 0.0.0.3
  network 192.168.88.4 0.0.0.3

LSW2配置

只配置Area0连接，其它通过路由引入直连。

#
sysname LSW2
#
