ENSP:VRRP+MSTP+DHCP配置

PC端的IP地址由AR1分配，在LSW1和 LSW2使用链路聚合和虚拟冗余，在LSW1-LSW8使用多生成树。VLAN 10 、 VLAN30 映射到instance 实例 1 ，VLAN 20 、VLAN40 映射到instance 实例2。LSW1为主根桥，LSW2为备份根桥。在LSW1中，实例1为主根,实例2为从根。在LSW2中，实例1从根,实例2为主根。

LSW5

#
vlan batch 10

interface Ethernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#
interface Ethernet0/0/2
 port link-type access
 port default vlan 10

LSW6-LSW8与LSW5配置大致相同，只是VLAN划分不同。
