管理vlan和办公vlan不是同一个,甚至是跨交换机。

实验名称

跨网段,跨vlan访问管理vlan

实验拓扑

                                                          跨网段跨vlan访问管理vlan_第1张图片       

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

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

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

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
