I want to use IPv6 SLAAC on all VLANs; additionally, RA's are required for IPv6 to work. The problem I have is that devices connected to one SSID (so one VLAN) are receiving RA's that are intended for another VLAN. This is not a router issue, else I'd be receiving RA's from VLAN 8 on my Linux and FreeBSD devices, but I…

As requested, I've attached the tcpdump output from both my MBP and Linux devices, along with a (slightly sanitized) startup-config…
