I've inherited a network with approximately 200 computers and no VLANs configured. We are currently adding a system that uses multicasting to communicate with each other and will be adding VoIP in 2 years. I'd like to set up VLANs, with which I had some experience 10 years ago, but I'm a bit rusty, and I need my memory cells re-awakened.
The network address is
10.110.32.0 255.255.252.0. I was thinking to set up a VLAN and subnet for the multicasting (6 devices) and use
10.110.34.224 255.255.255.224, but is the subnetting necessary or is the VLAN sufficient? In the past I did both subnetting and VLANs.
My second question is: does the router need to be configured with VLANs to support any of this? It's of course set up for the
10.110.32.0 network but management of the router is contracted out and I can't make any changes myself. Requests for changes take months so I'm hoping that I don't need to request a change or I'll need to request plans for future configurations as well. I'd rather not have to deal with them. QoS is already configured so that's covered for the VoIP at least.
