That the "interface" is a special one, with a "link" that doesn't function as other kinds of links do, that there's no "neighbour" per se to contact by an all-neighbour multicast for instance, no mechanism for the "all routers" multicast to work, etc (i.e. all of what the LLs were intended to support). To be clear I'm not against adding LLs, just that "the RFC says so" shouldn't be considered the main argument for that when it comes to WG. -- With respect, Roman
