#### Bước 1: Điền thông tin vào các ô màu vàng. <a href="#step-1-please-fill-in-the-formation-in-yellow-cells" id="step-1-please-fill-in-the-formation-in-yellow-cells"></a>

* VLAN & Port groups sẽ được tạo trên vDistributed Switch.

| **#** | **Port Group** | **VLAN**                                                    | **Remark**                         |

| 3     | Trunk          | <mark style="background-color:yellow;">140, 141, 142</mark> | Stretch L2 network traffic         |

* Cài đặt mạng cho NSX Autonomous Edge.

* Địa chỉ Public IP:

| On-premises Public IP                                       | HI GIO's Public IP                                          |
| ----------------------------------------------------------- | ----------------------------------------------------------- |
| <mark style="background-color:yellow;">\<IP Address></mark> | <mark style="background-color:yellow;">\<IP Address></mark> |
| {% endstep %}                                               |                                                             |

{% step %}
**Bước 2: Tạo port groups (VLANs) trên vCenter (nếu chưa có).**

#### Bước 3: Cấu hình VLAN & Security cho TRUNK port <a href="#step-3-configure-vlan-and-security-for-trunk-port" id="step-3-configure-vlan-and-security-for-trunk-port"></a>

* Tag VLAN:<br>

  <figure><img src="/files/avw3zD5tsuTqI1hMpec9" alt=""><figcaption></figcaption></figure>

* Cài đặt **Security**: bật chế độ Promiscuous mode và Forged transmits.

#### Bước 4: Tạo mạng trên HI GIO (các bước chi tiết có thể kiểm tra [tại đây](/hi-gio-user-guide-vn/network/1.-lam-viec-voi-mang-network/quan-ly-organization-vdc-networks.md)) <a href="#step-4-creating-network-on-hi-gio-detail-steps-can-check-here" id="step-4-creating-network-on-hi-gio-detail-steps-can-check-here"></a>

* Các mạng này được stretch layer 2 (cùng subnet như on-prem).
* Chọn IP cho gateway CIDR (**phải không trùng lặp địa chỉ IP**).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.higiocloud.vn/hi-gio-user-guide-vn/hi-gio-draas/stretching-layer-2-networks-cho-hi-gios-draas/chuan-bi-cau-hinh.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
