问题描述：
两台5800做了静态路由可以互通，一台接入的交换机不能访问外网，拼不通DNS
组网及组网描述：
两台5800做了静态路由互通，核心交换机的配置ip route-static 0.0.0.0 0 192.168.210.254 ip route-static 192.168.220.0 24 192.168.210.5
接入交换机的配置：附件

1、路由配置
2、NAT配置
都发下
你发的只有交换机的配置

感觉你路由写的不对，你这样，你把这个接入的vlan 2接口ip删了，（不用谢接口IP）。如果你核心写了dhcp的话，然后找个主机接在这个vlan20的物理接口下，这样这个台主机应该至少可以ping通你这个192.168.210.254，在往上ping254这台设备的外网接口，也应该是通的，如果不通，那说明254这台设备没写会城路由（没写去往vlan20网段的地址，下一跳抛给核心，即192.168.210.1）
ip route-static 192.168.220.1 255.255.255.0 192.168.210.1
(把这句写在192.168.210.254这个设备上）

254的地址就是H3C的登入界面。
核心没有DHCP,电脑接vlan20可以拼通210的其他的地址，但拼不通210.254
是在核心交换机上添加ip route-static 192.168.220.1 255.255.255.0 192.168.210.1
好的，我试下，谢谢！
254的地址就是H3C的登入界面。
