What are the consequences of having a subnet within a subnet? Eg. First network is 10.0.0.0/8 and the second is 10.0.1.0/24.
Thanks for everyone's replies. The original design, which is not my own, was to simply have two separate networks that have no need to communicate with each other. For some reason the tech that set it up did it this way. I realize that they are separate subnets and therefor unable to fully talk without routing. Just a little confusing that they were setup within each other.
My main concern though is if this would degrade performance within the 10.0.0.0/8 network because of unreturned responses from the 10.0.1.0/24 network's devices. Any ideas or am I crazy?

The hosts in 10.0.1.0/24 will not be able to communicate with any other hosts in any other subnets of 10.0.0.0/8 without a default-gateway.
The hosts in 10.0.0.0/8 will be able to communicate with all hosts in 10.0.0.0/8, which includes 10.0.1.0/24, but only one-way if the hosts in 10.0.1.0/24 do not have a default-gateway with access to both subnets.
