can we join two networks having different IPs and subnet mask through existing switches ?

Question

we have two different network(wired) system having different ips and subnet mask. Could we connect these networks. if yes what is the cheapest solution ? we are using switches in both the networks and both connected through separate LAN cable

Answer 1

A switch would not connect two networks together. A switch just expands one network. To connect two networks together, you would need a router. I would highly recommend getting a Cisco router.

Answer 2

You need a router or a layer 3 switch (which is a high class switch which you probably do not have). Here is some info on Layer 3 switching (http://compnetworking.about.com/od/hardwarenetworkgear/f/layer3switches.htm ) A layer 3 switch is like a router and can be programmed to connect two dissimilar networks together. If you do not have a layer 3 switch, you need to go down and purchase a router and then have someone configure it for you or buy a book about how to setup the connection between both network. I would be careful because if you are unfamiliar with routing you probably need to consult with someone or else you can cause problems on both networks.

Answer 3

To do this, the best way is through a Layer 3 switch (Cisco). And no, it's not cheap but you dont need a top of the line switch. Or you could use a bridge to connect the 2 subnets.



Good luck
