软路由ROS与H3C三层交换机组网配置

网络拓扑图

ROS的配置

第一步：定义Ros的WAN口及LAN口

将ether1定义为WAN口，连接光猫

ether2定义为LAN口，连接三层交换机

第二步：在Ros上添加PPPOE Client，

在Interface接口视图下，选择" + " 添加一个PPPOE Client

在General窗口，修改name及Interface两项
name ：PPPOE的名称（可自定义）
Interface ：选择WAN口（WAN口）

在Dial Out窗口下，输入user 及 password
User：PPPOE账号
Password：PPPOE密码
默认勾选User peer DNS（DNS服务器）及 Add Default Route（默认路由）），勾选后，无需手动添加DNS及静态路由，即可访问Internet。

在IP视图的Addresses窗口，单击 " + " 添加 ether2-LAN的接口地址：192.168.10.1/24

第三步：伪装（NAT）

在IP接口视图下，打开Firewall窗口的NAT，选择” + “ 添加
分别需要为每个网段都设置一条NAT

为192.168.200.0/24网段添加一条伪装

masquerade 伪装

第四步：添加回程路由

在IP-Routes视图下，
DST address(目标网段)：192.168.100.0/24
Gatway（LAN口及LAN口IP），相当于下一跳地址。：LAN
需要分别为每个网段添加回程路由（否则流量无法到达该VLAN，会导致出去的包回不来哦）
