三层交换机实验

配置：

SW1

[SW1]vlan batch 10  20
[SW1-GigabitEthernet0/0/1]port link-type access 
[SW1-GigabitEthernet0/0/1]port default vlan 10
[SW1-GigabitEthernet0/0/1]int g 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access 
[SW1-GigabitEthernet0/0/2]port default vlan 20
[SW1-GigabitEthernet0/0/2]int g 0/0/3
[SW1-GigabitEthernet0/0/3]port link-type trunk

[SW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20
 

SW2

[SW2]vlan batch 10 20
[SW2]interface GigabitEthernet 0/0/1
[SW2-GigabitEthernet0/0/1port link-type trunk 
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

[SW2]interface Vlanif 10 ---1、创建一个vlan10的接口；2、该接口可以修改vlan标签为10的数据
[SW2-Vlanif10]ip address 192.168.10.254 24
[SW2]interface Vlanif 20    
[SW2-Vlanif20]ip address 192.168.20.254 24

[sw2]vlan 99
[sw2]interface Vlanif 99
[sw2-Vlanif99]ip ad 192.168.99.1 24
[sw2]int g 0/0/2
[sw2-GigabitEthernet0/0/2]port link-type access 
[sw2-GigabitEthernet0/0/2]port default vlan 99

跑一个动态路由协议 使PC访问路由器的环回地址

[sw2]ospf 1 router-id 2.2.2.2
[sw2-ospf-1]area 0
[sw2-ospf-1-area-0.0.0.0]net 192.168.10.254 0.0.0.0
[sw2-ospf-1-area-0.0.0.0]net 192.168.20.254 0.0.0.0
[sw2-ospf-1-area-0.0.0.0]net 192.168.99.1 0.0.0.0
 

R1

[r1-GigabitEthernet0/0/0]ip ad 192.168.99.2 24
[r1-GigabitEthernet0/0/0]ip ad 192.168.99.2 24
[r1]ospf 1 router-id  4.4.4.4
[r1-ospf-1-area-0.0.0.0]net 192.168.99.2 0.0.0.0
[r1-ospf-1-area-0.0.0.0]net 192.168.100.254 0.0.0.0
