一、实验目标
掌握MSTP多生成树配置，VLAN配置，trunk配置，etherchannel配置
二、实验平台
系统：WIN7以上windows，X64版本。CPU支持虚拟化，并在Bios中开启虚拟化。内存最好3G以上.
软件：GNS3 1.4.0b3, VMware Workstation Pro 12，VM虚拟机：GNS3 VM (GNS3:1.4.0b3,VM:0.9.6) ,
IOU: i86bi-linux-l2-adventerprisek9-15.1a.bin
三、实验拓扑
![]()
四、实验需求
SW1/SW2之间启用etherchannel。
trunk:SW1-SW2,SW1-SW3,SW2-SW4,SW2-SW3,SW1-SW4.
交换机全部启用mst生成树.(name mst,revision 1.)
instance 1:vlan 10
instance 2:vlan 20
SW1: mst 1 root,mst 2 sec
SW2: mst 2 root,mst1 sec
vlan 10:pc1,pc3
vlan 20:pc2,pc4.

PC1:ip 192.168.1.1/24 192.168.1.254
PC2:ip 192.168.2.1/24 192.168.2.254
PC3:ip 192.168.1.2/24 192.168.1.254
PC4:ip 192.168.2.2/24 192.168.2.254
配置完毕，PC1和PC3可以ping通，PC2和PC4可以ping通。
SW1是vlan 10的root bridge,SW2是vlan 20的root bridge.
