Question

交换机f0/1端口划分到VLAN 10，f0/2端口划分到VLAN 20，要求分别配置交换机和路由器，实现两台主机互联

Answer 1

r1
int vlan 10
ip add 192.168.1.254 255.255.255.0
int vlan 20
ip add 192.168.2.254 255.255.255.0

s1
vlan 10
name 10
vlan 20
name 20
int fa0/1
sw mod acc
sw acc vlan 10
int fa0/2
sw mod acc
sw acc vlan 20
end

主机1
192.168.1.1 255.255.255.0 网关指向192.168.1.254
主机2
192.168.2.1 255.255.255.0 网关指向192.168.2.254
相互就可以通

Answer 2

交换机：
vlan 10 //创建van 10
vlan 20

interface FastEthernet0/1 //进入端口
switchport access vlan 10 //把vlan10划入到f0/1口
switchport mode access
!
interface FastEthernet0/2
switchport access vlan 20
switchport mode access
!
interface FastEthernet0/3
switchport mode trunk
switchport trunk allowed vlan all

路由器：

interface FastEthernet0/0.1
encapsulation dot1Q 10
ip address 192.168.1.1 255.255.255.0
!
interface FastEthernet0/0.2
encapsulation dot1Q 20
ip address 192.168.2.1 255.255.255.0

int f0/0
no shut //开启端口

pc配置：
设置ip、网关例如：IP：192.168.1.100 掩码：255.255.255.0 网关：192.168.1.1

Answer 3

SWITCH:
interface FastEthernet0/1
switchport access vlan 10
switchport mode access
!
interface FastEthernet0/2
switchport access vlan 20
switchport mode access
!
interface FastEthernet0/3
switchport trunk allowed vlan 10,20
switchport mode trunk

Router:
interface FastEthernet0/0.1
encapsulation dot1Q 10
ip address 192.168.1.1 255.255.255.0
!
interface FastEthernet0/0.2
encapsulation dot1Q 20
ip address 192.168.2.1 255.255.255.0
