 Networking logical topology
I am planning to set up two segments on my network. I would like to ask which logical topology would be best to use and would meet the following criteria:
1. at normal instances, segment A and B would be connected using 1 physical router. The router should detect them as 2 separate network segments.
2. at special instances, segment A and B can also be connected together making them 1 big network.
3. I also want security on the two segments. For instance, how can I prevent malware in segment A from infecting segment b?
another question, do i need to use a network OS (for example windows server) to accomplish this? by the way i am using a linksys router and the computers' OS varies from XP, vista and 7.

Software/Hardware used:
linksys router, xp, vista, 7

Answer Wiki:
what you asked for is not logical. but i can tell you what you can do.

1- get proper router, a linksys i doubt will do. a multilayer switch will be best.

2- make two different networks with /24 subnet. example. 10.0.1.0/24 and 10.0.2.0/24. and use two default gateways for ur end systems. 10.0.1.1, 10.0.2.1. this is seperate network.

3- if you want to make it into one big network, then change to /16 subnet in ur end systems, and make your default gateway for all systems 10.0.1.1.


------------------------------------

Your linksys would be sufficient if it supports more than one VLAN. If so, create the VLANs you need and establish inter-VLAN routing as desired...
