There are multicast and unicast nodes; to have multicast on just some
links, you'd presumably have the other links connecting unicast-only
nodes. 

What happens if you

set ns [new Simulator]

set EnableMcast_ 0
# create unicast nodes for unicast parts of network here

set EnableMcast_ 1
# create multicast-capable nodes for multicast-aware parts of network here

?

hasn't tried this, admittedly, but hasn't had much luck with multicast.
