Configurate Multiple PtP for Backhaul
The topology is like this, as follows.
For example, we use two pairs of G5250 as backhaul links and using Huawei switches to make the two link together.
Noted: Your switch must support link aggregation function.
First open the link aggregation function on your switch. Here is the configuration for Huawei switch.
[S1]interface Eth-Trunk 1
[S1]interface GigabitEthernet 0/0/23
[S1]interface GigabitEthernet 0/0/24
The configuration on Switch2 is the same.
Then configure the two PtP links. Here is the example.
