Hi, A senario: I have 2 applications using broadcast and multicast traffic to deliver data. Given a company of 8 departments (each dept 50 users), 6 departments (300 users) require those data. I intend to create multiple vlans based on the department however the 2 applications on separate servers will have difficulties deliver data to those vlans since vlan has its own broadcast domain. What is you opinion? My solutions: 1) Segregate based on services. Place those users who require the service into the same vlan as the 2 applications servers which use broadcast and multicast traffic. 2) Use vlan capable trunk card on the application servers. Create multiple vlans based on the department. Place the servers on a different vlan and trunk those 6 departments which require the application data to the server. What is a better solution? Why? In term of security which is better? Is there other solution? Thanks for taking your time. sPiDEr
