Re: [Int-area] WGLC for draft-ietf-intarea-broadcast-consider

Hi, all,

I think it would be useful to include a section explaining what is meant
by broadcast and multicast, and the current state of these.  In
particular, highlighting the following as context for these considerations:

    - all 1's broadcast is supposed to never transit routers (RFC1812)

    - as a default, subnet-directed broadcast shouldn't be going past
routers either (RFC2644)

    - multicast in IPv6 may have limited scope (e.g., not all uses are
to "all-nodes")

    - duplicate address detection in IPv6 sends only to the multicast
group that would be joined by another party with the same address

    - relays, such as for DHCP, proxy ARP, etc., can extend the scope of
broadcast and multicast beyond the originator's original intent

These each limit (or extend) who can see a broadcast/multicast message -
and can be used in consideration of the extent to which information in
the message leaks out.

I.e., "all broadcast is not equal", and "all multicast is not equal".
