Multicast Problem.....



Hi there~~~

I compared 3 multicast routing protocol....
(pimDM, CtrMcast, DynamicDM.....)
and.. some point was wrong.....

First, I tested in ns-version 2.1b4. 3 protocols worked fine... but... i can't find 'prune & graft message'..
when i tested 2 protocols, I use 'udp', 'application/traffic/cbr'...
it is very curious.... and so on.... finally i tested 3 protocols with "Agent/CBR".
Wow... I can see prune & graft message....
Why? Why can't i see theses message with 'udp', 'application/traffic/cbr' ??????

please tell me.....

Second, case of CtrMcast,  i can see just cbr message, in ns2-1b4. ( i don;t know about ip-multicast...... ^.^!!!)
and then in tested in ns-2.1b5(daily snapshot)
wow, i can see 'encap' message.... what is 'encap' message??????

please tell me............

Third, In ns-2.1b5(daily snapshot), i can't use dynamicDM, error is.. (i can;t remember detail...)
Error message is "what is dynamicDM, pimDM....".
In daily snapshot Just DM is working fine.....

why??? it is bug ??? why don't......?????????
