Sysadmin here that's been asked to solve a network problem. I've got a multisite network connected via elan and I've been asked to spin up a network for our internet of things devices. They only need an internet connection, they need to be isolated from our other networks.
Create the /22 on our Internet Router (provides dhcp) ->802.1q trunk-> Core switch -> elan to remote sites -> tagged ports on switches at remote sites?
I'm sure I'm overlooking something. Or if there's a better way to accomplish this please let me know. I've never been a fan of flat layer 2 networks but that's what I'm working with. We're not about to deploy additional routers and switch to layer 3 between sites.
