Cisco配置SVI

Switch Virtual Interfaces（SVI）

使用SVI实现VLAN间互访

实验拓扑

配置交换机

Switch#configure 
Switch(config)#interface e0/0
Switch(config-if)#switchport mode access 
Switch(config-if)#switchport access vlan 10
Switch(config-if)#exit

Switch(config)#interface e0/1
Switch(config-if)#switchport mode access 
Switch(config-if)#switchport access vlan 20

Switch(config)#ip routing 
Switch(config)#interface vlan 10
Switch(config-if)#ip address 192.168.10.254 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit

Switch(config)#ip routing 
Switch(config)#interface vlan 20
Switch(config-if)#ip address 192.168.20.254 255.255.255.0
Switch(config-if)#no shutdown

配置PC2和PC3

PC2

[root@PC2 /]# ip address add 192.168.10.2/24 dev eth1
[root@PC2 /]# ip route add default via 192.168.10.254 dev eth1

配置PC3

[root@PC3 /]# ip address add 192.168.20.3/24 dev eth1
[root@PC3 /]# ip route add default via 192.168.20.254 dev eth1

ping测试

[root@PC2 /]# ping 192.168.20.3
