The draft mandates that conforming implementation uses RFC4361 so there should be no problem of lacking chaddr on the client side. I think we should also mention that RFC6842 should be implemented on the server side so as it respects a client identifier, not chaddr. Before the client gets the tunnel configuration the tunnel interface doesn't exist. The 4o6 client just generates the client identifier (unique by IAID) for the tunnel to be established. Once the v4 configuration is complete, the tunnel is created and the client associates the client identifier with this tunnel/interface. Marcin
