We are installing a Cisco 3560 to provide broadband to a multi office building. All users will be in same VLAN as our switch will be across the street with fibre running over to the new office. We plan to use 'switcport protection' to stop users from seeing eachother and block broadcast traffic. However issue is that one of the offices uses the web site of one of the other offices which is hosted on site. So can we expect the Cisco to route at L3 even though we have port protection enabled?
All offices will be provided with public IP via Cisco DHCP with a mask of 255.255.252.0. The VLAN IP will be the Default Gateway.
