Subject: [magma] Multicast Router Discovery - Destination addresses

An open issue that needs addressing is the destination
addresses for the various messages.  Currently, all the
messages are sent to the all-hosts address.  This was
originally done to allow arbitrary nodes to learn of
multicast routers.  However, that functionality does
lead to additional processing for all nodes on a link.

My proposed change is to define an All-Snoopers mcast
address for v4 and v6.  Solicitation messages will be
sent to the All-Routers address.  Advertisement and
Termination messages will be sent to the newly defined
All-Snoopers address.

One open question is whether we need an All-Mcast-Routers
address.

Comments?  Disagreements?

Regards,
Brian
