As this discussion is a comparison of capabilities between a true mesh link and the Aruba 501 wireless bridge, I have further questions about multicast traffic.
Is multicast traffic supported on the Aruba 501 so that wired clients can receive it?
The 501 configuration guide says only IPv4 traffic is allowed, but does this include multicast or does the 501 not know where to forward it? Could "redirecting unsupported traffic" (pg.32) achieve this for multicast?
