跨网段跨vlan访问管理vlan

实验名称

跨网段，跨vlan访问管理vlan

实验拓扑

思路：

 Trunk/默认路由（等于思科默认网关）

说明:

管理vlan 1，要求从PC能访问任意vlan 1.

//配置SW1

<H3C>system-view

[H3C]sysname SW1

[SW1]int vlan1

[SW1-Vlan-interface1]ip  add 192.168.1.1 29

[SW1-Vlan-interface1]vlan  10

[SW1-vlan10]int  vlan10

[SW1-Vlan-interface10]ip  add 192.168.10.1 24

[SW1-Vlan-interface10]vlan  20

[SW1-vlan20]int  vlan20

[SW1-Vlan-interface20]ip  add 192.168.20.1 24

[SW1-Vlan-interface20]quit

//配置接口为trunk

[SW1]int g1/0/1

[SW1-GigabitEthernet1/0/1]port  link-type trunk

[SW1-GigabitEthernet1/0/1]port  trunk permit vlan 10   //不写all，避免垃圾流量。

[SW1-GigabitEthernet1/0/1]int  g1/0/2

[SW1-GigabitEthernet1/0/2]port  link-type trunk

[SW1-GigabitEthernet1/0/2]port  trunk permit vlan 20

//SW1配置完毕

//配置SW2

<H3C>syst

[H3C]sysn SW2

[SW2]int g1/0/1

[SW2-GigabitEthernet1/0/1]port  link-type trunk

[SW2-GigabitEthernet1/0/1]port  trunk  permit vlan 10

[SW2-GigabitEthernet1/0/1]int  g1/0/2

[SW2-GigabitEthernet1/0/2]port  link-type access

[SW2-GigabitEthernet1/0/2]vlan  10

[SW2-vlan10]port  g1/0/2

[SW2-vlan10]int  vlan1

[SW2-Vlan-interface1]ip  add 192.168.1.2 29

//vlan 1 IP已配完，但10网段的访问不到，还需要添加默认路由

[SW2]ip  route-static 0.0.0.0 0 192.168.1.1

//配置SW3，和SW2一样

<H3C>syst

[H3C]sysn SW3

[SW3]int g1/0/1

[SW3-GigabitEthernet1/0/1]port  link-type trunk

[SW3-GigabitEthernet1/0/1]port  trunk  permit vlan 20

[SW3-GigabitEthernet1/0/1]int  g1/0/2

[SW3-GigabitEthernet1/0/2]port  link-type access

[SW3-GigabitEthernet1/0/2]vlan  20

[SW3-vlan20]port  g1/0/2

[SW3-vlan20]int  vlan1

[SW3-Vlan-interface1]ip  add 192.168.1.3 29

[SW3]ip  route-static 0.0.0.0 0 192.168.1.1

实验验证：全网互通
