Section 2.7 says:

Interface-Local scope spans only a single interface on a node
and is useful only for loopback transmission of multicast.

It should say:

Interface-Local scope spans only a single interface on a node 
and is useful only for loopback transmission of multicast.
Packets with interface-local scope received from another node 
must be discarded.

Notes:

It should be explicitly stated that interface-local scoped multicast packets
received from the link must be discarded.
The BSD implementation currently does this, but not Linux.
