I have question regarding to control traffic between VLAN. My VLAN located in Core switch and I need to prevent VLAN 10 from Accessing VLAN 20 and the same time I need VLAN 20 to access VLAN 10.
how to block access from vlan 1 to other vlan 2:
access-list 100 deny ip 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255
access-list 100 permit ip any any
ip access-group 100 in
Please rate if it helps.
if you do this then you will also restrain vlan 2 to speak to vlan 1, don't forget that IP communication is bidirectionnal.
