Auto discover multiple subnets

[t.advisor]

Config details - We have 2 subnets which talk at the switch
10.10.0.0 - 10.20.0.0 all devices on the 10.10 are hardwired and able to autodiscover devices on 10.10. and 10.20.

My challenge. 10.20 devices are all airport devices and are able to autodiscover only other wireless units. I can attach to a wired device on 10.10 if manually configured, but it does not autopopulate for quick attachment. There are approx 300 devices needing changes, and would rather autodiscover vs manually type all the ip's. Any thoughts for why these wireless units will not autodiscover cross subnet would be appreciated.

I am certainly no expert on IP addresses, but your problem seems obvious. You know that all nodes on the 10.x.x.x domain are invisible to the outside world. That is why you use 10.x.x.x IP addresses. Similarly, all nodes on the 10.10.x.x subdomain should be invisible to all other subdomains. Your 10.20.x.x nodes are visible, but your 10.10.x.x nodes are not. Therefore, your 10.10.x.x devices can see your 10.20.x.x nodes, but the reverse is not true.
