PC端配置：配置ip地址
交换机1配置：①创建VLAN
system-view
vlan 10
vlan 20
②配置PC端接口
interface gi 1/0/1
port link-type access
port access vlan 10
interface gi 1/0/2
port link-type access
port access vlan 10
interface gi 1/0/3
port link-type access
port access vlan 20
interface gi 1/0/4
port link-type access
port access vlan 20
③配置交换机接口
interface gi 1/0/48
port link-type trunk
port trunk permit vlan 10 20
交换机2配置：①创建VLAN
system-view
vlan 10
vlan 20
2.配置交换机接口
interface bridge-aggregation 1
qu
interface rang gi1/0/46 to gi1/0/48
port link-mode bridge
port link-aggregation group 1
qu
interface bridge-agg 1
port link-type trunk
port trunk permit vlan all
路由器配置:
interface bridge-aggregation 1
qu
interface rang gi1/0/0 to gi1/0/3
port link-mode bridge
port link-aggregation group 1
qu
interface bridge-agg 1
port link-type trunk
port trunk permit vlan all
