super-VLAN

需求:

公司网络已经运行好多年了,由于当初设计缺陷,整个公司在一个VLAN中,存在大量的广播风暴,严重影响了公司使用网络,公司领导决定更换华为设备并且重新划分VLAN,但是不改变终端PC的设置。经论证决定采用super-VLAN.划分财务部使用VLAN 10,工程部使用VLAN 20,super-VLANW为30.

拓扑如下:

汇聚交换机配置:

vlan batch 10 20 30 100
#
vlan 30
 aggregate-vlan
 access-vlan 10 20
#
interface Vlanif30
 ip address 10.1.1.254 255.255.255.0
 arp-proxy inter-sub-vlan-proxy enable
#
interface Vlanif100
 ip address 192.168.1.1 255.255.255.0
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 100
#

LSW2配置:

#
vlan batch 10
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 10
#
LSW3配置:

 

#
vlan batch 20
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 20
#
interface GigabitEthernet0/0/2
 port link-type access
