三層交換機基礎配置
案例3：三層交換配置路由
3.1 問題
如何使用三層交換機實現全網互通？
配置思路：
1.終端設備PC設置
2.交換機配置
-建立vlan 10 20 30 40
-與pc連接接口設置acc模式 加入對應vlan
-與三次交換連接接口設置trunk模式並通過所有vlan
注意：所有交換機的vlan一致
3.三層交換配置
-建立vlan 10 20 30 40
-與交換機接口設置trunk並允許全部vlan
-設置ip地址是進入int vlanif 10 20 30 40
4.驗證與測試
[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
[SW3]vlan batch 10 20 30 40
