一。vlan
1. vlan 1
quit
interface vlan-interface 1
port e 1/0/23

二。路由
1。交换机：
ip route-static 0.0.0.0 0.0.0.0 192.168.60.1 #删除此条路由会如何？
#ip route－static 192.168.61.0 255.255.255 192.168.61.1 ＃三层交换机不需要设此条路由，会自动抓取
2. 路由器(192.168.60.1)添加回指路由：
把内网的4个段 指向192.168.60.2 VLAN1的接口IP
ip route 192.168.61.0 255.255.255 192.168.60.2 ＃不设置回指路由会如何？
ip route 192.168.62.0 255.255.255 192.168.60.2
ip route 192.168.63.0 255.255.255 192.168.60.2
ip route 192.168.64.0 255.255.255 192.168.60.2
