Title : Simplifying IPv6 MLD Snooping Switches

The purpose of this draft is to simplify the design of MLD Snooping
switches and provide a method for sending Solicited Node multicast
addresses to be send to every port to improve network security and
management.
IPv6 Addressing Architecture requires that all nodes must join the
associated Solicited-Node multicast addresses for every unicast and
anycast address it is assigned. This causes MLD snooping switches
to create potentially huge multicast forwarding tables just to
handle Neighbor Discovery. A simple change to alleviate this would
be to allow switches to forward a range of addresses that include
the Solicited-Node multicast addresses to every port. This also
could help in network discovery and discovering security breaches
as discussed in [spoof]. Similarly the same allowance could be made
for Local Network Control Block (LNCB) addresses.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
