路由器的三层接口可以做端口聚合吗

二层动态聚合配置举例

1. 组网需求

·     Device A与Device B通过各自的二层以太网接口GigabitEthernet1/0/1～GigabitEthernet1/0/3相互连接。

·     在Device A和Device B上分别配置二层动态链路聚合组，并实现设备间VLAN 10和VLAN 20分别互通。

2. 组网图

3. 配置步骤

(1)     配置Device A

# 创建VLAN 10，并将端口GigabitEthernet1/0/4加入到该VLAN中。

<DeviceA> system-view

[DeviceA] vlan 10

[DeviceA-vlan10] port gigabitethernet 1/0/4

[DeviceA-vlan10] quit

# 创建VLAN 20，并将端口GigabitEthernet1/0/5加入到该VLAN中。

[DeviceA] vlan 20

[DeviceA-vlan20] port gigabitethernet 1/0/5

[DeviceA-vlan20] quit

# 创建二层聚合接口1，并配置该接口为动态聚合模式。

[DeviceA] interface bridge-aggregation 1

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

[DeviceA-Bridge-Aggregation1] quit

# 分别将端口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

# 配置二层聚合接口1为Trunk端口，并允许VLAN 10和20的报文通过。

[DeviceA] interface bridge-aggregation 1

[DeviceA-Bridge-Aggregation1] port link-type trunk

[DeviceA-Bridge-Aggregation1] port trunk permit vlan 10 20

[DeviceA-Bridge-Aggregation1] quit

(2)     配置Device B

Device B的配置与Device A相似，配置过程略。

4. 验证配置

# 查看Device A上所有聚合组的详细信息。

以上信息表明，聚合组1为非负载分担类型的二层动态聚合组，包含有三个选中端口。

三层动态聚合配置举例

1. 组网需求

·     Device A与Device B通过各自的三层以太网接口GigabitEthernet1/0/1～GigabitEthernet1/0/3相互连接。

·     在Device A和Device B上分别配置三层动态链路聚合组，并为对应的三层聚合接口配置IP地址和子网掩码。
