The draft is Informational, but contains this:


4.3 IP forwarding and ARP

    Unlike normal point-to-point IGP circuit, the IP nexthop for the
    routes using this p2p-over-lan circuit as an outbound interface is
    not optional.  The IP nexthop address has to be a valid interface
    or internal address on the adjacent router. This address is used by
    local router to obtain the MAC address for IP packet forwarding.
    Proxy ARP has to be enabled if the address is not the adjacent
    interface IP address.

Reading this it's not clear to me whether this a requirement for
correct configuration (and so not strictly a protocol change) or a new
requirement on the implementations (which looks more like
a protocol change).

Clue appreciated,
