S5700三层交换机,复杂网络环境设置默认路优先级实战。

一、拓扑图

\

新加核心交换机在分中心,分别连区域中心上传路段视频,和路由器去映射内网手机发布服务器,远程手机查看视频,内网服务器必须上网。

二、问题描述

现在分中心上传区域中心视频正常,手机发布服务器不能上网,手机无法远程观看视频。

三、解决方案

查看核心交换机的静态路由器,发现默认路由指向区域分中心。核心交换机与路由器之间互联可以相互ping通,就是无法上网。

发现所有上网请求都被发往区域中心(默认路由的作用),增加一条指向路由器的默认路由,修改优先级为50,(默认60)

配置代码如下:

[GLZX_hexin_s5700]ip route-static 0.0.0.0 0.0.0.0 172.16.10.1 preference 50

[GLZX_hexin_s5700]ping 218.30.67.83 (上网正常)
