### 实验拓扑

![图1-1][1]

### 实验需求

1. asw03到asw01和asw02使用DRNI技术链路聚合
2. 要求当asw01或asw02链接asw03链路任意一条出现故障但还可确保业务能正常转发

---

### 实验解法

*步骤 1：在 asw01和asw02上配置 Keepalive 链路到asw02使三层技配置ip能互通，然后打上Text使查询时方便辨别*

```
[asw01]interface Ten-GigabitEthernet 1/0/49
[asw01-Ten-GigabitEthernet1/0/49]port link-mode route 
[asw01-Ten-GigabitEthernet1/0/49] description Keepalive
[asw01-Ten-GigabitEthernet1/0/49] ip address 1.1.1.1 30

[aswo2]interface Ten-GigabitEthernet 1/0/49
[aswo2-Ten-GigabitEthernet1/0/49]port link-mode route 
[aswo2-Ten-GigabitEthernet1/0/49]description Keepalive
[aswo2-Ten-GigabitEthernet1/0/49] ip address 1.1.1.2 30
```

*步骤 2：在 asw01和asw02 上创建 DRNI系统Mac(这个Mac地址正常建议配置自己真实的桥mac地址，这个地址需要两端都一样)、系统编号和配置Keepalive源目IP[正常需在配一条系统优先级但我看默认32768都一样所以懒没配（这个优先级和IRF不同需要一致）] ，*

```
[asw01]drni system-mac 1-1-1
[asw01]drni system-number 1
[asw01]drni keepalive ip destination 1.1.1.2

[aswo2]drni system-mac 1-1-1
[aswo2]drni system-number 2
[aswo2]drni keepalive ip destination 1.1.1.1
```

*步骤 3：配置IPP链路的链路聚合，然后打上Text便于查询时方便辨别*

```
[asw01]interface Bridge-Aggregation  10
[asw01-Bridge-Aggregation10]description IPP
[asw01-Bridge-Aggregation10]link-aggregation mode dynamic  
[asw01]interface range FortyGigE  1/0/53 FortyGigE 1/0/54
[asw01-if-range]port link-aggregation group  10

[aswo2]interface Bridge-Aggregation 10
[aswo2-Bridge-Aggregation10]description IPP
[aswo2-Bridge-Aggregation10]link-aggregation mode  dynamic 
[aswo2]interface range FortyGigE 1/0/53 FortyGigE 1/0/54
[aswo2-if-range]port link-aggregation group  10
```

*步骤 4：将asw01 和 asw02 的 聚合口配置为IPP接口*

```
[asw01]interface Bridge-Aggregation  10
[asw01-Bridge-Aggregation10]port drni intra-portal-port 1

[aswo2]interface Bridge-Aggregation  10
[aswo2-Bridge-Aggregation10]port drni intra-portal-port 1
```

*步骤 5：将 asw01和asw02 链接其他口的链路配置为动态聚合和加入到分布式DRNI聚合口中*

```
[asw01]interface Bridge-Aggregation  1
[asw01-Bridge-Aggregation1]link-aggregation mode  dynamic 
[asw01-Bridge-Aggregation1]port drni group  1
[asw01]interface Ten-GigabitEthernet 1/0/50
[asw01-Ten-GigabitEthernet1/0/50]port link-aggregation group 1

[aswo2]interface Bridge-Aggregation  1
[aswo2-Bridge-Aggregation1]link-aggregation mode dynamic 
[aswo2-Bridge-Aggregation1]port drni group 1
[aswo2]interface Ten-GigabitEthernet 1/0/51
[aswo2-Ten-GigabitEthernet1/0/51]port link-aggregation group  1
```

*步骤 6：将 asw03链接asw02和asw01设备的接口加入到动态聚合组中*

```
[asw03]interface Bridge-Aggregation  1
[asw03-Bridge-Aggregation1]link-aggregation mode dynamic 
[asw03]interface range Ten-GigabitEthernet 1/0/50 Ten-GigabitEthernet 1/0/51
[asw03-if-range]port link-aggregation group  1
```

*效果测试：将asw01和asw02分别创建个管理地址然后在asw03外带个设备ping asw01和asw02当关闭 asw01 的 XGE_1/0/50 口时外带设备仍然都能互通即完成实验**

*实验现象：查询Keepalive时UP、查询system、查询asw03聚合*

```
