Re: Regarding Multicasting

Ok I didn't understood this thing

"Dont forget that PIM=Protocol Independent Multicast hence it can work

the mcast source via any interface and with appropriate static mroute
command evry thing shud work fine.'

Can you please explain under my questions that I have asked..

Thanks
