Leaking of RAs between VLANS is expected behavior as RA are multicast.
Because the 802.11 protocol sends multicast traffic as broadcast over the
air and every device on a BSSID shares the same group key for encryption,
any client can decode any multicast packet, including RAs not on the same
VLAN.

I posed a similar question at the social media constituent group meeting at
a previous EDUCAUSE conference. How about I make a new venue for cohort

I got a resounding NO! from them. They said use existing venues...
Bruce,
Not to side track this conversation too far, but is this because the ArubaOS is
that stable or that it is not as prevalent?
This is almost an exact reason for something like this to exist. In a perfect
world this collaborative site would have sub-forums for the different vendors.
I know I have just been assuming Aruba people have no issues, since I never
see them on the list! ;)
