What is the best practise in implementing vlan following scenario ?

By Sagar!!! ·
I have 40 cisco switches 1 L3 and others L2. All switches except 2 or 3 have direct connectivity to L3 switch which is the core. Core connects to the servers. There are no redundant connections or any particular need for any 2 systems to interact between them, so is switches.
Organisation is divided into many branches but each branch has only 2 or 3 or 4 client PCs. Till now all except voice traffic were working on single vlan. Now I need to implement different vlans. What is the best practise. Should I put each branches in different vlan which comes to be somewhere 25 vlans with just having 2 or 3 pc in one vlan and a single switch sometimes has 5 vlans or more. What is the best practise. Please help asap

you state that all these sites are on the same VLAN. Are they on the same subnet?

To back up a bit, a VLAN is helpful to divide a large physical network into smaller virtual networks, mostly as a way to contain broadcast traffic and ensure things that need good QOS (like VoIP) actually work.

I would assume that your remote sites each has a router and separate subnet already? If that is the case, unless one of those sites has a lot of users, there is no need to use VLANs to segment the network.
