1、组网需求

1.1 需求

设备LSW1和LSW2进行DRNI组网，正常工作时链路进行负载分担且任何一台设备故障对业务均没有影响，保证业务的高可靠性。
LSW1&2的G1/0/1、G1/0/2为IPL链路，G1/0/5为Keeplive链路，G1/0/3为下联LSW3接口
LSW3的G1/0/1和G1/0/2做链路聚合组网图
以H3C S6900设备配置为例

1.2 组网图

2、配置步骤

2.1 LSW1配置

\\系统配置
注：
DR的MAC地址必须一样，可以设置成主设备的MAC地址
DR系统中不同DR设备的系统编号不同
DR接口的系统优先级要相同
<LSW1> system-view
[LSW1] drni system-mac 1-1-1
[LSW1] drni system-number 1
[LSW1] drni system-priority 123

\\配置Keepalive报文的目的IP地址和源IP地址
[LSW1] interface gigabitethernet 1/0/5
[LSW1-GigabitEthernet1/0/5] port link-mode route
[LSW1-GigabitEthernet1/0/5] ip address 1.1.1.1 24
[LSW1-GigabitEthernet1/0/5] quit
[LSW1] drni mad exclude interface GigabitEthernet1/0/5
[LSW1] drni keepalive ip destination 1.1.1.2 source 1.1.1.1
{
或者使用聚合口（例如1023），配置为动态聚合模式，配置Keepalive报文的目的IP地址和源IP地址
[LSW1] interface Route-Aggregation1023
[LSW1-Route-Aggregation1023] description keepalive
[LSW1-Route-Aggregation1023] ip address 1.1.1.1 255.255.255.252
[LSW1-Route-Aggregation1023] link-aggregation mode dynamic
# 将接口23加入聚合组1023中
[LSW1] interface GigabitEthernet1/0/5
[LSW1-GigabitEthernet1/0/5]  port link-mode route
[LSW1-GigabitEthernet1/0/5]  description keepalive
[LSW1-GigabitEthernet1/0/5]  port link-aggregation group 1023
# 配置Keepalive报文的目的IP地址和源IP地址。
[LSW1] drni keepalive ip   destination 1.1.1.2 source 1.1.1.1 
[LSW1] drni mad exclude interface Route-Aggregation1023
[LSW1] drni mad exclude interface GigabitEthernet1/0/5
}

\\配置IL链路
创建二层聚合口接口3，并配置为动态聚合模式，把端口G1/0/1和G1/0/2加入聚合组3中，聚合组3配置为IPP口，接口链路类型为Trunk且运行所有vlan通过

[LSW1-Bridge-Aggregation3] port link-type trunk
[LSW1-Bridge-Aggregation3] port trunk permit vlan all
[LSW1-Bridge-Aggregation3] quit


\\配置下联链路

3、验证配置

\\查看LSW1上分布式聚合的Keepalive报文信息。
[LSW1] display drni keepalive
Neighbor keepalive link status: Up
Neighbor is alive for: 104 s, 16 ms
Last keepalive packet sending status: Successful
Last keepalive packet sending time: 2024/12/03 10:12:09 620 ms
Last keepalive packet receiving status: Successful
Last keepalive packet receiving time: 2024/12/03 10:12:09 707 ms
 

Distributed relay keepalive parameters:

\\查看LSW1上IPP口和DR口的摘要信息和详细信息
[LSW1] display drni summary
[LSW1] display drni verbose

\\查看LSW3上聚合组4的详细信息。
[LSW3] display link-aggregation verbose bridge-aggregation 4
