# 在您的路由器上配置 BGP

在 zenConsole 上建立 BGP 会话后，为了启用 BGP 互联，您需要在自己的路由器上配置 BGP。

{% hint style="info" %} <mark style="color:blue;">**注意**</mark>

* <mark style="color:blue;">确保您熟悉 BGP 配置，并在必要时咨询专业人士。</mark>
* <mark style="color:blue;">BGP 配置可能因路由器型号和路由器操作系统（IOS）版本的不同而有所差异，如有需要，请参考路由器手册。</mark>
  {% endhint %}

## 操作步骤

1. **进入三层网络配置模式**\
   登录您的路由器并进入配置模式。这通常通过命令行接口（CLI）使用 SSH、Telnet 或控制台连接完成。\\
2. **进入 BGP 配置模式**\
   进入三层网络的配置模式后，通过输入以下命令进入 BGP 配置模式：

   ```typescript
   router bgp <your-as-number>
   ```

   将 `<your-as-number>` 替换为您的自治系统编号（ASN）。\\
3. **配置 BGP 邻居关系**

   配置 BGP 邻居关系以建立与其他路由器的连接。使用以下命令：

   ```typescript
   neighbor <neighbor-ip-address> remote-as <neighbor-as-number>
   ```

   将 `<neighbor-ip-address>` 替换为您的 BGP 邻居的内网 IP 地址，即 BGP 会话详情中的对等 IP；将 `<neighbor-as-number>` 替换为对等 ASN（65534）。\\
4. **配置 BGP 路由策略**
   * 创建路由策略：`route-map <route-map-name> permit 10`
   * 匹配路由：`match ip address 1` \\
5. **激活 BGP 邻居关系**\
   配置完 BGP 邻居关系和路由策略后，使用以下命令激活 BGP 邻居关系：

   ```typescript
   neighbor <neighbor-ip-address> activate
   ```

   将 `<neighbor-ip-address>` 替换为您的 BGP 邻居的内网 IP 地址，即 BGP 会话详情中的对等 IP。

示例

```python
pythonCopy coderouter bgp 65000
neighbor 10.0.0.1 remote-as 65534
route-map to-as65534 permit 10
  match ip address 1
neighbor 10.0.0.1 activate
```

6. **保存配置**\
   配置完 BGP 后，确保将配置更改保存到三层网络的运行配置中。使用以下命令：

   ```arduino
   arduinoCopy codewrite memory
   ```

   或

   ```arduino
   arduinoCopy codecopy running-config startup-config
   ```

   这样可以确保配置更改在重启后仍然保留。\\
7. **验证配置**\
   使用各种 show 命令（例如 `show ip bgp`、`show ip bgp neighbor`）验证 BGP 是否已正确配置并正常运行。

## 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.console.zenlayer.com/welcome/cn/global-bgp/establish-bgp-session/configure-bgp-on-your-router.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.
