Huawei ensp link aggregation comprehensive experiment

1. Prepare the experimental environment
   
2. First, add the interfaces of the two switches to their respective VLANs
   
3. Configure the two switches with lacp and create a trunk group to add the interface to the trunk group, and allow all VLANs to pass
   
   

4. Configure trunk2 in sw1 and add the interface to the group, allowing vlan to pass

5. Configure the trunk group in ar1 and add the interface to the trunk group (router configuration trunk needs to be changed from layer 2 to layer 3)
   
6. Configure single-arm routing in ar1, that is, dhcp treats the trunk group as a whole into the sub-interface of the trunk to configure single-arm routing
   
   
7. Create a new trunk group on the right side of ar1 and add the interface to the group and configure the ip address and refer to the one-hop default route
   
8. Create two different trunk groups on the left and right sides of ar2, add the interface to the group, configure the ip address, and refer to two static routes
   
9. Create a trunk group in ar3 to add the interface to the group and refer to a default route
   
10. Configure the remote management password in sw2, and enter vlan10 to create an ip address, point to your own gateway, and use ar3 to remotely manage sw2
    
    
11. Realize the whole network interoperability
