  1. 配置LSW1 的优先级以及冗余配置 
    [Huawei]sySname SW1
[SW1]lacp priority 1000
[SW1]int Eth-Trunk 1
[SW1-Eth-Trunk1]bpdu enable
[SW1-Eth-Trunk1]mode lacp-static
[SW1-Eth-Trunk1]int e0/0/10
[SW1-Ethernet0/0/10]eth-trunk 1
[SW1-Ethernet0/0/10]int e0/0/11
[SW1-Ethernet0/0/11]eth-trunk 1
[SW1-Ethernet0/0/12]int e0/0/12
[SW1-Ethernet0/0/12]eth-trunk 1
[SW1]dis eth-trunk 1                        
Least Active-linknumber: 1  Max Active-linknumber: 8                          
Ethernet0/0/10         Unselect 100M     32768   11     289     10100010  1     
Ethernet0/0/11         Unselect 100M     32768   12     289     10100010  1     
Ethernet0/0/12         Unselect 100M     32768   13     289     10100010  1

    配置最大跑的链接数

    [SW1]int Eth-Trunk  1
[SW1-Eth-Trunk1]max active-linknumber 2
[SW1-Eth-Trunk1]dis eth-trunk 1                       
Least Active-linknumber: 1  Max Active-linknumber: 2                          
ActorPortName          Status   PortType PortPri PortNo PortKey PortState Weight
Ethernet0/0/10         Unselect 100M     32768   11     289     10100010  1     
Ethernet0/0/11         Unselect 100M     32768   12     289     10100010  1     
Ethernet0/0/12         Unselect 100M     32768   13     289     10100010  1
  2. 配置LSW2 ，不需要配置优先级和最大链路数 
    [Huawei]sysname SW2
[SW2]int Eth-Trunk 1
[SW2-Eth-Trunk1]bpdu enable
[SW2-Eth-Trunk1]mode lacp-static
[SW2-Eth-Trunk1]q
[SW2]int e0/0/10
[SW2-Ethernet0/0/10]eth-trunk 1
[SW2]int e0/0/11
[SW2-Ethernet0/0/11]eth-trunk 1
[SW2-Ethernet0/0/11]q
[SW2]int e0/0/12
[SW2-Ethernet0/0/12]eth-trunk 1
[SW2-Ethernet0/0/12]q
[SW2]dis eth-trunk 1                         
Operate status: up          Number Of Up Port In Trunk: 2                     
Ethernet0/0/10         Selected 100M     32768   11     289     10111100  1     
Ethernet0/0/11         Selected 100M     32768   12     289     10111100  1     
Ethernet0/0/12         Unselect 100M     32768   13     289     10110000  1

    3.配置LSW1, LSW2的网关IP
    配置SW2

    [SW2]int vlanif 1
[SW2-Vlanif1]ip add 192.168.10.3 24
[SW2-Vlanif1]dis ip int brief
Interface                         IP Address/Mask      Physical   Protocol  
MEth0/0/1                         unassigned           down       down      
NULL0                             unassigned           up         up(s)     
Vlanif1                           192.168.10.3/24      up         up

    配置SW1

    [SW1]int vlanif 1
[SW1-Vlanif1]ip add 192.168.10.2 24
[SW1-Vlanif1]dis ip int brief
Interface                         IP Address/Mask      Physical   Protocol  
MEth0/0/1                         unassigned           down       down      
NULL0                             unassigned           up         up(s)     
Vlanif1                           192.168.10.2/24      up         up

    4.配置LSW1的Eth- Trunk2

    [SW1]int Eth-Trunk 2
[SW1-Eth-Trunk2]trunkport GigabitEthernet 0/0/1 to 0/0/2
[SW1-Eth-Trunk2]dis eth-trunk 2
PortName                      Status      Weight 
GigabitEthernet0/0/1          Up          1      
GigabitEthernet0/0/2          Up          1

    5.配置R1

    [Huawei]sysname R1
[R1]int Eth-Trunk 2
[R1-Eth-Trunk2]trunkport GigabitEthernet 0/0/0 to 0/0/1
[R1-Eth-Trunk2]ip add 192.168.10.1 24
[R1-Eth-Trunk2]display ip int brief
Interface                         IP Address/Mask      Physical   Protocol  
Eth-Trunk2                        192.168.10.1/24      up         up   
[R1-Eth-Trunk2]int Eth-Trunk 1
[R1-Eth-Trunk1]trunkport GigabitEthernet 0/0/2 to 0/0/3
[R1-Eth-Trunk1]ip add 12.0.0.1 30
[R1-Eth-Trunk1]display ip int brief
Interface                         IP Address/Mask      Physical   Protocol  
Eth-Trunk1                        12.0.0.1/30         up         up        
Eth-Trunk2                        192.168.10.1/24      up         up

    6.配置R2

    [R2]interface Eth-Trunk 5
[R2-Eth-Trunk5]trunkport g 0/0/2 to 0/0/3
[R2-Eth-Trunk5]ip add 12.0.0.2 30
[R2-Eth-Trunk5]dis ip int brief
Interface                         IP Address/Mask      Physical   Protocol  
Eth-Trunk5                        12.0.0.2/30          up         up

    R2需要配置静态路由

    [R2]ip route-static 192.168.10.0 24 12.0.0.1
[R2]display ip routing-table
   12.0.0.0/30  Direct  0    0           D   12.0.0.2        Eth-Trunk5
   12.0.0.2/32  Direct  0    0           D   127.0.0.1       Eth-Trunk5
  127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0
  127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0
192.168.10.0/24  Static  60   0          RD   12.0.0.1        Eth-Trunk5
