Re: [Roll-bier-dt] roll-bier-dt

Hello Toerless:

Well, there is as Carsten says a multicast support for RPL storing mode, but not for non-storing. This is where Carsten's draft comes in to play.
In normal BIER, the bits indicate the routers, don't they? So there's an IP packet inside, correct, like in my tunnel mode? But then I expect it is the same packet for all destinations. So how does htat work, is it a mcast packet or do all the destination have a same IP address?
