# 项目实战 - 内外网互联
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
- **需求**
|
|||
|
|
- SW5通过vlanif15和出口设备R1互联
|
|||
|
|
- SW6通过vlanif16和出口设备R1互联
|
|||
|
|
- 在SW5/SW6与出口设备R1中配置路由，实现SW5/SW6与R1的互通
|
|||
|
|
- 公司出口设备 R1连接外网，公司租用的公网网段：100.1.1.0/29
|
|||
|
|
- 公司内网主机有访问外网的需求，所以在R1上配置默认路由，下一跳为公网网关
|
|||
|
|
- 使用ACL来定义允许那些部门和网段访问外网
|
|||
|
|
- 部署地址池NAT或者Easy-ip，实现内网主机访问外网
|
|||
|
|
- 配置VRRP的上行链路跟踪
|
|||
|
