交换机分出来的路由器怎么设置（从交换机上接出的路由器如何设置） - 原点资讯

在网络架构中，三层交换机和路由器都扮演着非常重要的角色。三层交换机主要用于在局域网内部进行数据包转发和过滤，而路由器则用于连接不同的网络并进行路由选择和跨网络通信。正确配置三层交换机和路由器可以提高网络的性能和安全性，从而确保网络的正常运行。然而，由于网络配置的复杂性和多样性，不同的网络架构可能需要不同的配置方法。在本篇文章中，我整理了一份通用的三层交换机和路由器配置方法，以帮助有需要的友友们更好地了解相关技能。希望友友们可以从中获得一些有用的信息。

实验内容及目标：

1、不同Vlan 下的客户端能够访问外网【2.2.2.1】

2、了解路由器和三层交换机之间的连接及配置

3、了解三层交换机和接入交换机之间的连接及配置

实验拓扑图：

实验设备及版本：

本实验所用到的设备为：

1、交换机：华为 Quidway S5700-28C-HI VRP (R) software, Version 5.110

2、路由器：华为 AR1200 VRP (R) software, Version 5.130

3、PC主机：

实验过程：

一、建立物理连接

按照拓扑图进行组网

二、接入交换机配置

这里以红框内的第一个交换机为例

<Huawei>sys Enter system view, return user view with Ctrl Z.

其他的几个接入交换机配置过程相同，配置时，注意接口。
