VLAN路由-每个VLAN一个物理接口

在二层交换机上配置VLAN，路由器为每一个VLAN分配一个物理接口。

设备规划表

SWA配置

[SWA]vlan batch 2 3
[SWA]interface GigabitEthernet0/0/1
[SWA-GigabitEthernet0/0/1]port link-type access
[SWA-GigabitEthernet0/0/1]port default vlan 2
[SWA-GigabitEthernet0/0/1]interface GigabitEthernet0/0/2
[SWA-GigabitEthernet0/0/2]port link-type access
[SWA-GigabitEthernet0/0/2]port default vlan 3
[SWA-GigabitEthernet0/0/2]interface GigabitEthernet0/0/3
[SWA-GigabitEthernet0/0/3]port link-type access
[SWA-GigabitEthernet0/0/3]port default vlan 2
[SWA-GigabitEthernet0/0/3]interface GigabitEthernet0/0/4
[SWA-GigabitEthernet0/0/4]port link-type access
[SWA-GigabitEthernet0/0/4]port default vlan 3

PTA配置

[RTA]interface GigabitEthernet0/0/1
[RTA-GigabitEthernet0/0/1]ip address 192.168.2.254 24
[RTA]interface GigabitEthernet0/0/2
[RTA-GigabitEthernet0/0/2]ip address 192.168.3.254 24 

验证

主机A与主机B之间可以互ping通

VLAN路由-单臂路由

将交换机和路由器之间的链路配置为Trunk链路，并且在路由器上创建子接口以支持VLAN路由。

VLAN路由-三层交换

在三层交换机为每个VLAN创建一个VLANIF接口作为网关。
