一、实现目标及图例：

1.VLAN规划：

        PC1：VLAN10

        PC2：VLAN20

        PC3：VLAN30

        PC4：VLAN40

        LSW1与LSW2互联链路：VLAN100

2.网段规划：

VLAN	网关地址	网段
VLAN10	192.168.10.1/24	192.168.10.0/24
VLAN20	192.168.20.1/24	192.168.20.0/24
VLAN30	192.168.30.1/24	192.168.30.0/24
VLAN40	192.168.40.1/24	192.168.40.0/24
VLAN100（互联）	LSW1：192.168.100.1；LSW2：192.168.100.2	192.168.100.0/24

二、代码配置

  network 192.168.100.0 0.0.0.255
quit

2.LSW2交换机

dhcp enable
vlan batch 30 40 100
 
interface GigabitEthernet 0/0/2
 port link-type trunk
 port trunk allow-pass vlan 30 40
 
interface GigabitEthernet 0/0/1
 port link-type trunk
 port trunk allow-pass vlan 100
 
interface Vlanif 30
 ip address 192.168.30.1 255.255.255.0
 dhcp select global
 
interface Vlanif 40
 ip address 192.168.40.1 255.255.255.0
 dhcp select global
 
interface Vlanif 100
 ip address 192.168.100.2 255.255.255.0
 
ip pool vlan30
 network 192.168.30.0 mask 255.255.255.0
 gateway-list 192.168.30.1
 dns-list 8.8.8.8
quit
 
ip pool vlan40
 network 192.168.40.0 mask 255.255.255.0
 gateway-list 192.168.40.1
 dns-list 8.8.8.8
quit
 
ospf 1 router-id 2.2.2.2
 area 0
  network 192.168.30.0 0.0.0.255
  network 192.168.40.0 0.0.0.255
  network 192.168.100.0 0.0.0.255
quit

3.LSW3交换机

vlan batch 10 20
 
interface GigabitEthernet 0/0/2
 port link-type access
 port default vlan 10
 
interface GigabitEthernet 0/0/3
 port link-type access
 port default vlan 20
 
interface GigabitEthernet 0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20

4.LSW4交换机

vlan batch 30 40
 
interface GigabitEthernet 0/0/2
 port link-type access
 port default vlan 30
 
interface GigabitEthernet 0/0/3
 port link-type access
 port default vlan 40
 
interface GigabitEthernet 0/0/1
 port link-type trunk
 port trunk allow-pass vlan 30 40

三、实验检查情况

1、查看接口VLAN划分情况

2、查看三层接口IP信息

1.LSW1交换机

2.LSW2交换机

3、查看OSPF进程配置

1.LSW1交换机

2.LSW2交换机

4、查看OSPF下的路由条目

5、DHCP下IP配置信息

四、试验全网可通性

1.PC1pingPC2

2.PC1pingPC3

3.PC1pingPC4

4.PC4pingPC1
