Example for Multiple Users to Perform the Same Configuration for a Service in Two-Phase Validation Mode

This section provides an example for multiple users to perform the same configuration for a service on one router in two-phase validation mode.

Networking Requirements

As shown inFigure 1, both user A and user B log in to the router. After user A configures a service on the router, user B performs the same configuration for the service on the router.

Figure 1 Networking for multiple users to perform the same configuration for a service in two-phase validation mode

When the configuration committed by user B is the same as that committed by user A, the system notifies user B that the configuration conflicts with an existing configuration.

Configuration Roadmap

The configuration roadmap is as follows:

Simulate a situation in which user A and user B perform the same configuration for a service.
Simulate a situation in which user A commits the configuration.
Simulate a situation in which user B commits the configuration.

Data Preparation

To complete the configuration, you need an interface IP address.

Procedure

Simulate a situation in which user A and user B perform the same configuration for a service.
- Simulate a situation in which user A sets the IP address of GigabitEthernet 0/1/4 to 10.1.1.1 on the router.
```
<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/4
[~HUAWEI-GigabitEthernet0/1/4] ip address 10.1.1.1 24
```
- Simulate a situation in which user B sets the IP address of GigabitEthernet 0/1/4 to 10.1.1.1 on the router.
```
<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/4
[~HUAWEI-GigabitEthernet0/1/4] ip address 10.1.1.1 24
```
Simulate a situation in which user A commits the configuration.
```
[*HUAWEI-GigabitEthernet0/1/4] commit
```

Simulate a situation in which user B commits the configuration.

The system notifies user B that the configuration conflicts with an existing configuration.

[*HUAWEI-GigabitEthernet0/1/4] commit
ip address 10.1.1.1 24
Error: The address already exists.

Commit canceled, the configuration conflicted with other user, you can modify 
the configuration and commit again.
