RFC 3306 states:
"The scope of the unicast-prefix based multicast address MUST NOT exceed the scope of the unicast prefix embedded in the multicast address." I'd just like to verify my interpretation that site-local multicast addresses MAY be formed from ULA prefixes? If so, should a particular value (e.g. 0x0000) be used as the subnet ID portion of the prefix? Thanks, -K-
