HCL模拟器下做M-LAG测试（以及和华为配置对比）-二层架构

news 来源：原创 2024/9/30 8:04:31

1.简单二层架构

1.1 拓扑图

在这里插入图片描述

1.2 配置

1.2.1 Leaf1配置

system-mac必须配置，否则会有一个node处于unknown状态，即使配置主节点的mac，主节点也需要配置system-mac为自己的mac

## M-LAG配置[Leaf1] m-lag system-mac 0001-0001-0001			# 手动设置MAC，通常建议使用主设备的系统MAC，另一台设备配置需相同
[Leaf1] m-lag system-number 1				# 数字小的成为主设备，
[Leaf1] m-lag system-priority 130				# 两台的优先级需要一样
[Leaf1] m-lag mad exclude interface GigabitEthernet1/0/13	# 配置保留接口，这个接口会在脑裂后不会被关闭
[Leaf1] m-lag consistency-check disable			# 模拟器中配置完成后，会报一致性检测失败的错，导致接口起不来，使用这条命令能解决，但生产环境中慎用## keepalive链路配置[Leaf1] interface g1/0/13
[Leaf1-GigabitEthernet1/0/13]ip address 10.1.1.1 255.255.255.252
[Leaf1] m-lag keepalive ip destination 10.1.1.2 source 10.1.1.1	# 配置DAD检测接口## peer-link接口配置[Leaf1] interface Bridge-Aggregation10
[Leaf1-Bridge-Aggregation10] link-aggregation mode dynamic
[Leaf1]interface GigabitEthernet 1/0/11
[Leaf1-GigabitEthernet1/0/11] port link-aggregation group 10
[Leaf1]interface GigabitEthernet 1/0/12
[Leaf1-GigabitEthernet1/0/12] port link-aggregation group 10
[Leaf1] interface Bridge-Aggregation10
[Leaf1-Bridge-Aggregation10] port m-lag peer-link 1## M-LAG接口配置[Leaf1]int Bridge-Aggregation 5
[Leaf1-Bridge-Aggregation5] port link-type trunk
[Leaf1-Bridge-Aggregation5] port trunk permit vlan all
[Leaf1-Bridge-Aggregation5] link-aggregation mode dynamic
[Leaf1]interface GigabitEthernet 1/0/1
[Leaf1-GigabitEthernet1/0/1] port link-aggregation group 5
[Leaf1]int Bridge-Aggregation 5
[Leaf1-Bridge-Aggregation5] port m-lag group 5

华为的做法中，peer-link需要关闭STP

1.2.2 Leaf2配置

Leaf2和Leaf1的配置只有细微的差异

## M-LAG配置[Leaf2] m-lag system-mac 0001-0001-0001			
[Leaf2] m-lag system-number 2				
[Leaf2] m-lag system-priority 130				
[Leaf2] m-lag mad exclude interface GigabitEthernet1/0/13	
[Leaf2] m-lag consistency-check disable			## keepalive链路配置[Leaf2] interface g1/0/13
[Leaf1-GigabitEthernet1/0/13]ip address 10.1.1.2 255.255.255.252
[Leaf2] m-lag keepalive ip destination 10.1.1.1 source 10.1.1.2	## peer-link接口配置[Leaf2] interface Bridge-Aggregation10
[Leaf1-Bridge-Aggregation10] link-aggregation mode dynamic
[Leaf2]interface GigabitEthernet 1/0/11
[Leaf1-GigabitEthernet1/0/11] port link-aggregation group 10
[Leaf2]interface GigabitEthernet 1/0/12
[Leaf1-GigabitEthernet1/0/12] port link-aggregation group 10
[Leaf2] interface Bridge-Aggregation10
[Leaf1-Bridge-Aggregation10] port m-lag peer-link 1## M-LAG接口配置[Leaf2]int Bridge-Aggregation 5
[Leaf1-Bridge-Aggregation5] port link-type trunk
[Leaf1-Bridge-Aggregation5] port trunk permit vlan all
[Leaf1-Bridge-Aggregation5] link-aggregation mode dynamic
[Leaf2]interface GigabitEthernet 1/0/1
[Leaf1-GigabitEthernet1/0/1] port link-aggregation group 5
[Leaf2]int Bridge-Aggregation 5
[Leaf1-Bridge-Aggregation5] port m-lag group 5

1.2.3 SW配置

下行交换机上只需要配置链路聚合即可

[H3C]interface Bridge-Aggregation 5
[H3C-Bridge-Aggregation5] port link-type trunk
[H3C-Bridge-Aggregation5] port trunk permit vlan all
[H3C-Bridge-Aggregation5] link-aggregation mode dynamic[H3C] interface range GigabitEthernet 1/0/1 to GigabitEthernet 1/0/2
[H3C-if-range] port link-aggregation group 5

1.3 配置验证

这里只验证基本的通信即可，因此在三台交换机上都起了一个VLAN100，并测试连通性，主要查看的内容是m-lag配置是否生效，已经生成树是否达到的预期的效果

1.3.1 M-LAG
