三层交换机基础配置

案例3：三层交换配置路由
3.1 问题
如何使用三层交换机实现全网互通？

配置思路：
1.终端设备PC设置
2.交换机配置
-建立vlan 10 20 30 40
-与pc连接接口设置acc模式 加入对应vlan
-与三次交换连接接口设置trunk模式并通过所有vlan
注意：所有交换机的vlan一致
3.三层交换配置
-建立vlan 10 20 30 40
-与交换机接口设置trunk并允许全部vlan
-设置ip地址是进入int vlanif 10 20 30 40
4.验证与测试

[SW1]vlan batch 10 20 30 40
Info: This operation may take a few seconds. Please wait for a moment...done.
[SW1]int e0/0/1
[SW1-Ethernet0/0/1]port link-type acces
[SW1-Ethernet0/0/1]port default vlan 10
[SW1-Ethernet0/0/1]int e0/0/2
[SW1-Ethernet0/0/2]port link-type access
[SW1-Ethernet0/0/2]port default vlan 20
[SW1-Ethernet0/0/2]int e0/0/3
[SW1-Ethernet0/0/3]port link-type trunk
[SW1-Ethernet0/0/3]port trunk allow-pass vlan all

SW2相同
