Creating a VLAN for another company.

[mawright1]

Hello, 

I have a general question regarding and certain situation for two companies and creating a VLAN.

So the back story is there is a large company with a large infrastructure cabling included, now a small business completely separate to the large business want to run there network with the same building, but to save on cost etc the idea is to have a Internet connection installed with a router but then connect into the larger companies switch with a dedicated VLAN and then on another switch within the same VLAN connect the smaller companies switch and then connect the PCs etc to that.

I hope that makes sense, i try to be simple and to the point! 

My question to all of this is if this is possible are the interfaces connected as switch ports for the smaller company and does the larger company use a interface configuration of a trunk port or an access port? 

thanks in advance!

You might want to look into using VRF Lite to achieve what you describe. You will find some discussion of that feature in this link which I hope will be helpful

So the smaller company will have an Internet router at one location and a switch of their own in another and then connect the two via the larger company's switch network across a dedicated VLAN. Yes that is entirely possible.

If the larger company will be managing the switch at the smaller company's location, then it would probably be best if it was a trunk connection so that the larger company could manage the switch on a separate network (VLAN) than the smaller company.

If the smaller company is managing its own switch, then the connection to the larger could be an access port in the proper VLAN just to keep it simple.

Hope this helps
