三层交换机做单臂路由

三层交换机做单臂路由

拓扑：

搭建步骤：

1 在sw1 和sw3上创建vlan ， 并将与主机相连的接口设为access并分到相应vlan上

SW1:

sysname SW1

vlan batch 10 20

interface GigabitEthernet0/0/10

port link-type access

port default vlan 10

interface GigabitEthernet0/0/20

port link-type access

port default vlan 20

SW3:

sysname SW3

vlan batch 10

interface GigabitEthernet0/0/10

port link-type access

port default vlan 10

将两个交换机的vlan出口的接口设为trunk，并允许所有vlan进出

SW1:

interface GigabitEthernet0/0/2

port link-type trunk

port trunk allow-pass vlan 2 to 4094

SW3:

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 2 to 4094

重点：三层交换机上 做配置

Sw2:

sysname SW2

vlan batch 10 20

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 2 to 4094

interface GigabitEthernet0/0/2

port link-type trunk

port trunk allow-pass vlan 2 to 4094

#

interface Vlanif10

ip address 192.168.1.1 255.255.255.0

interface Vlanif20

ip address 10.224.9.1 255.255.255.0
