拓扑图:
环境描述:
1、SW1作为DHCP服务给给PC机和AP分发地址,所有DHCP的地址池的网关都是172.16.0.1/18。路由器作为出口网关设备。
2、vlan 12/19/20/99等vlan的地址都是DHCP自动获取,出单机手动指定地址。
3、交换机与交换机相连的口都是Trunk,核心SW1与R1相连的接口是access口并加到vlan 3里,配置与路由器下联口一个段的地址。
4、AP1获取的地址:172.16.14.11/24;CW:172.16.10.11/24;HR:172.16.9.11/24;HCT:172.16.2.11/24;AP2:172.16.14.12/24。
问题:
交换机下的PC和AP端都能自动获取到地址,但是ping不通172.16.0.1/18网关地址;出单机由于是手动设置的IP地址,而且在172.16.0.1/18这个大段里面没有包括出单机和Server服务器端,所以在R1上写了调回程路由,172.210.0.0 255.255.252.0 172.16.0.2,有了回程路由后出单机就可以ping通Internet了,但是像交换机下的PC和AP的网段,我在R1上写了回程路由也ping不通网关,是什么问题?
