[ns] Doubts on routing objects

[Andrea Josi <mr_josi@yahoo.it>]

Hi,

i have two questions on how to use the following
objects:

* routingTable_ : 

in DV routing simulations, every node is in charge of
bringing up to date its own routing tables:
i would like to know (being DV the routing protocol
used) if using the simulator's routelogic is 
an other way to get valid (up-to-date) routing
informations 


* RtModule/Mcast :

when this module is attached to a node, it is inserted
in the routing modules' chain called "rtnotif_", why ?

doesn't this bring to the fact that when a new
("unicast") route has to be installed with 
"add-route", it is installed also in the multicast
classifier ???


Thanks for your help :)
