I am in the process of setting up Router on a stick. A simple scenario:
1. Cisco Router (x1)
2. 1 Cisco Switch 2960
3. Other brand switches connecting to the Cisco 2960
I would like to know the following
a. I have Vlan 1, 2, 3. What is the best way to avoid Vlan 2 and 3 from communicating, but Vlan 2 and 3 need to talk to Vlan 1. (Should I block this via Access-list on the router) or is there an easy way to do it on the switch?
