交换机S5560S划分VLAN后VLAN之间不能PING通

主路由MSR 5200    192.168.100.1

S5560S  192.168.100.2

在S5560上，

1-20口是VLAN1，24口是VLAN1

21口是VLAN2，22口虽VLAN3，23口是VLAN4

建立VLAN

vlan 1 

 vlan 2 to 4

给VLAN分配IP地址

 interface Vlan-interface1

 ip address 192.168.100.2 255.255.255.0 

interface Vlan-interface2 

 ip address 192.168.20.1 255.255.255.0 

interface Vlan-interface3

 ip address 192.168.30.1 255.255.255.0 

interface Vlan-interface4 

 ip address 192.168.40.1 255.255.255.0 

端口加入对应的VLAN

interface GigabitEthernet1/0/21 

 port link-mode bridge 

 port access vlan 2 

 stp edged-port #

interface GigabitEthernet1/0/22 

 port link-mode bridge

 port access vlan 3 

 stp edged-port 

# interface GigabitEthernet1/0/23

 port link-mode bridge

 port access vlan 4 

 stp edged-port 

去往主路由的静态路由

ip route-static 0.0.0.0 0 192.168.100.1

路由上写三条返回的静态路由

ip route-static 192.168.20.0 24 Vlan-interface1 192.168.100.2

 ip route-static 192.168.30.0 24 Vlan-interface1 192.168.100.2

 ip route-static 192.168.40.0 24 Vlan-interface1 192.168.100.2

配置完上面的命令后，核心交换机上VLAN2，VLAN3，VLAN4的电脑都可以访问外网，都可以PING通192.168.100.1,192.168.100.2

但是VLAN2，VLAN3，VLAN4下的电脑互相PING不通，并没有加ACL策略，请问是哪块设置不对吗？
