Hi,
I am novice in multicasting.
I have few question relating to multicasting & PIM-SM concepts.
1. Who will assign multicasting group addresses? Is it assigned through IANA??
Does that mean now we have only multicast group from 224.0.0.1 to 239.255.255.255 ?
I wonder only these many multicast group exist in the world.
2. How big is PIM-SM domain?
These multicast routing protocol doesnot talk about any Inter-domain & Intra-domain things.
So does this mean that PIM-SM domain spreads through out the internet?
If not, how is Inter-domain multicast routing done?
If yes, only one Bootstrap router exist through out Internet?
Can anyone clarify these questions? You might feel these questions are silly. But I am a novice & just starting
off in multicasting things. Please let me know if I am wrong anywhere.
Thanks in advance,
Srinivas
