• An Edgerouter that’s aware of VLANs will route between those subnets/VLANs unless explicitly told not to via firewall rules.

    If you can ping devices across your VLANs, then nmap will scrape them.

    nmap 192.168.0.0/16 -sn
    

    ...will scan for all hosts across all subnets beginning with 192.168.x.x
