ICMP

Hi, I have created three V-lans:

Vlan1 192.168.12.0 SL 100

Vlan2 192.168.13.0 SL 50

Vlan3 192.168.14.0 SL 50

Now from higher security network which is Vlan1 network, i m nt able to ping any device of the other lower security V-lans. The all network traffic is already exempted. Please Advice!!
