Reviewed by Brian Carpenter, Gen-ART His review: Summary: No objection This draft suggests an optimization for multicast through L2TP tunnels, such that the same flow will not be sent more than once between the same two L2TP end-points. This is a Good Thing if it can be achieved - it doesn't however guarantee a logical multicast topology (any more than the MBONE does). It is quite complex and adds some administrative configuration tasks. Experimental seems appropriate, since it isn't clear whether this will prove deployable at a large scale. The draft is quite well written, but I did notice one nit: > 4.2. Group state determination Source Filtering Group > Management Protocols require querier routers... "querier" doesn't seem like an English word to me. Logically, it should be, but I don't think it is. It certainly isn't an adjective.
