[ns] Multicast receiver on a leaf node

[Andrea Josi <mr_josi@yahoo.it>]

Hi,

i am trying to implement a multicast routing protocol;
i've taken as a starting point the protocols allready
implemented in NS :)

i can't understand how does an agent A that joined a
multicast group and that is on a leaf node for that
group, succeed in receiving something:
when it joins the group, no replicator is installed on
the node, so, what does it happen when packets arrive
?
I would expect that a new replicator, pointing to A
(only), is installed.
Is this achieved by using the "handle-cache-miss"
method ? how ?

Thanks in advance.
