Optimize network space for IP addresses

Sudhanshu Gupta explains how to use a Cisco 2600 Router to get networks to talk to each other.

I have a flat network and I am running out of IP addresses. I would like to create a subnet for each department or a separate subnet for some additional addresses. How do I get the networks to talk to each other using a Cisco 2600 router?

You have a tough task ahead of you. My suggestion is to plan everything on paper. You need to subnet the flat network,...

create a VLAN for each of the subnets and then do inter-VLAN routing. Apart from that, you need to have a VLAN for common services like apps servers, DHCP, DNS, etc. which need to be reachable by all VLANs. One VLAN should be kept separate for management/administration purposes. Also, keep in mind scalability requirements for the future.
