Hi, All,

I am currently studying and implementing MAODV draft
and having some questions.

In MAODV, a group member or a tree member should
maintain both unicast and multicast routing table. 
But unlike unicast routing table, there is not a 
"Lifetime" field in multicast routing table. Obviously
it is not necessary to maintain a multicast entry
forever. But when and how to obsolete them? Should I
follow the same rule of unicast routing table? Also,
if a node has multiple next hops in its next hop list,
they(next hops) might be added at different time. Does
every next hop need a timer for its lifetime? When 
should the multicast entry become invalid, when one of
the next hop timeouts or all of its next hop timeout?

Well, it is quite enough. Any comments would be
appreciated.

Thank,
