Switch lab―单臂路由

 

最简单的路由转发拓扑—单臂路由

1.switch0新建vlan 10,20

2.switch0与switch1 建立VTP server和client，互相学习vlan

3.交换机间trunk模式，allowed vlan all

switch0和router0间trunk模式，allowed vlan all

4.两台PC不同vlan不同网段

vlan 10   PC0 192.168.1.254 255.255.255.0 192.168.1.1

vlan 20   PC1 192.168.2.254 255.255.255.0 192.168.2.1

5.router0与switch0相连口起子接口

子接口配置规则：

interface f0/x

    no shut

interface f0/x.[1~410000]

    encapsulation dotlq [vlan ID]

    ip address [网络地址][子网掩码]

interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
!

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
!

 

 6.PC各自ping网关，互ping
