交换机和路由器如何做链路聚合实现通信

路由器的不能配置vlan，只能做三层聚合。如果要终结vlan的只能做子接口

(1)     配置Device A

# 创建三层聚合接口1，配置该接口为动态聚合模式，并为其配置IP地址和子网掩码。

<DeviceA> system-view

[DeviceA] interface route-aggregation 1

[DeviceA-Route-Aggregation1] link-aggregation mode dynamic

[DeviceA-Route-Aggregation1] ip address 192.168.1.1 24

[DeviceA-Route-Aggregation1] quit

# 分别将接口GigabitEthernet1/0/1至GigabitEthernet1/0/3加入到聚合组1中。

[DeviceA] interface gigabitethernet 1/0/1

[DeviceA-GigabitEthernet1/0/1] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface gigabitethernet 1/0/2

[DeviceA-GigabitEthernet1/0/2] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/2] quit

[DeviceA] interface gigabitethernet 1/0/3

[DeviceA-GigabitEthernet1/0/3] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/3] quit

(2)     配置Device B

Device B的配置与Device A相似，配置过程略。
