Two clients share a town house together; Each has "X" number of floors. One has the top few the other the bottom. The issue is there are a number of IP security cameras, some private to each network and about 6 that they must share (front door, back door, etc).
So here is what I am thinking for a network design. (I'm open to any ideas you might have and please feel free to criticize the network design in it's entirety. I never take this stuff personally.)
Potential Networks: 3 separate switches backboned each with their own IP range. 10.1.10.x -- top floors -- gets own Internet router 10.1.11.x -- shared IP security cameras 10.1.12.x -- bottom floors -- gets own Internet router
Issues: 2 separate networks that need to share IP video cameras each will have there own Internet access and IP router
Question: How to best allow them to share the middle IP range but not cross over to the other network?
Answer: Subnet networks with 255.255.254.0 potentially allowing each network to have access to the 10.1.11.x address.
Potential problem: 10.1.12.x network might have issues with broadcast; it will be looking for that to be in 10.1.13.255 which we will not be using...
Other network design idea (which is also a Question): can two 10.1.10.x networks that are 'side by side' share a 10.1.11.x network but not each others packets?
Problem: no shared network closet...
