I have two separate networks - one is for 6x computers and a file server, the other is for 6x VoIP phones and a PBX.
The two networks are intended to be totally separate - they each have their own, different dedicated internet connections, and thus they each also have their own router. The two routers are on different subnets.
Can I use a single Gigabit smart switch for both networks? E.g.:
...and just put ports 1-12 on VLAN 1, and ports 13-24 on VLAN 2? Will that work and will the two DHCP servers running on the two routers stay out of each other's way?
If it IS doable, is it advisable to set up the network this way just to save us from having to buy a second smart switch, or is there an important reason to have it two separate switches (e.g. to shield the voip network from congestion due to the LAN traffic from the computers communicating with the file server)?
