Simpler solution... Just set the P flag and use your unicast prefix as =
part of the group ID.
For example, if your unicast prefix is 2001:db8:f00d::/48, you could =
use:
ff4e:2001:db8:f00d::<group number>
Where <group number> is any number of your choosing up to 64 bits, but =
recommended
to be =E2=89=A432 bits.
Make sense?
