链路捆绑实现冗余功能实验

Posted 2021-02-18

1.在华为模拟器ensp上设置两个普通路由器，两个交换机，两台PC
先打开ensp ，新建2个路由器和2个pc用户，分别用网线连接,如下图

2. 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

3. 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

   7.PC测试网络
