Scenario is that we have 837 router and Cisco 2960 switches in branch office. What I am trying is to divide lan network in two vlans. But 837 doesn't support vlans and 2960 doesn't do inter vlan routing. So is there a way I could setup this and still able to separate lan into two segments. It is not necessary that they should be on different subnets. I want to block communication between these two segments.
