Re: [lisp] LISP Use Cases

> Casn you expand a bit.  It is not obvious to me that either IoT or Mobile Node needs multicast support from LISP for its LISP usage.

On IoT or mobile node may want to send multicast packets. Those multicast packets need to get to receivers. The receivers may be at LISP sites.

If you want to support other transports and you want to stretch L2 subnets, then ARP and IPv6 link-local multicast will need to be supported. That means the overlay needs to transport multicast packets.

Right. And a node in a VPN site can be anywhere.

SDN, in my mind is a network management mechanism. When we talk about the LISP architecture and protocols, we are talking about in-network control-plane mechanisms (and I mean between nodes in the network in a distributed fashion).
