谁可以帮忙解决一下思科的题
三层交换机设置了DHCP协议之后，路由器也设置了默认路由，为什么PC机不能ping路由器的与三层交换机的连接接口。如果再加几台二层交换机又该怎么设置？配置命令1、三层交换机的配置命名和创建vlanSwitch>enSwitch#config tEnter configuration commands, one per line.

江湖救急{:6_278:}， 三层交换机还需要起一个SVI，配上192.168.1网段的IP地址， 你现在交换机跟路由器没有直连网段，所以下层PC机PING不到路由器的。 anubis_amon 发表于 2018-4-26 17:00

是三层交换机和路由器之间需要一个网段吗，有试过的，还设置了默认路由回指，但是pc机还是ping不通 雾黎 发表于 2018-4-26 20:30

路由器跟三层交换机之间肯定需要一个直连网段的，这样连接之后其实相当于路由器跟PC都是分属在同一个三层交换机下不同VLAN的，然后三层交换机起了路由功能，VLAN间就能相互通信。看网络设备的配置还真没看出啥毛病来。我感觉建好交换机跟路由器的直连网段，应该就能通信了。PC能正常获得IP和网关吧？ {:6_268:} 三层开启：IP routing就好了
