The assign global-ip command assigns a public IP address to the virtual system.
The undo assign global-ip command deletes the public IP address assigned to the virtual system.
assign global-ip start-address end-address { exclusive | free }
undo assign global-ip start-address end-address
| Parameter | Description | Value |
|---|---|---|
| start-address end-address | Specifies a public IP address range for the virtual system. | The start IP address and end IP address are in dotted decimal notation. |
| exclusive | Indicates the exclusive mode. | - |
| free | Indicates the free mode. | - |
No public IP address is assigned to the virtual system by default.
Usage Scenario
Source NAT, NAT Server or NAT64 configured in virtual systems require public IP addresses. In such cases, run the assign global-ip command in the root system to assign public IP addresses to virtual systems.
Configuration Impact
Public IP addresses can be assigned in the following modes:
Exclusive mode
The public IP address assigned in exclusive mode to a virtual system cannot be assigned to other virtual systems.
Free mode
The public IP address assigned in free mode to a virtual system can still be assigned in free mode only to other virtual systems.
start-address and end-address indicate the same IP address when their values are the same.
After a public IP address is assigned in exclusive or free mode to a virtual system, the NAT address pool and NAT Server global address in the root system cannot be the IP address any more.
Precautions
When you configure NAT address pools or NAT Server in virtual systems, the IP addresses in the NAT address pool and the global address of NAT Server must be the IP addresses in the public IP address ranges assigned to the virtual systems. Otherwise, the configuration will fail to be delivered.
