Hi, sorry for bothering. I would like to know how MLDv2 can currently work Without being temporarily being forced to MLDv1 mode, Even if all listeners have MLDv2 implemented.
RFC2461 (even the newest draft <draft-ietf-ipv6-2461bis-02.txt> ) Requires on page 56, chapter 7.2.1 interface initialization - To use MLD [MLD] for joining group of solicitated node Multicast address. As [MLD] is a referenc to RFC 2710, This means MLDv1. MLDv2 RFC states, that a listener must work in MLDv1 mode for Some time, if it receives an MLDv1 Query on that interface. A MLDv2 router must work in MLDv1 mode for some time , if it receives a MLDv1 Report for a specific address. A MLDv1 router sends Queries for an address, if he receives A Done. So if the IPv6 node shuts down its interface or drops A private address and therefore leaves the multicast group of the Solicitated node address - all Multicast listeners are temporary forced To MLDv1 mode by the Address queries in response to the done message. Is that desired or is something wrong with the above conclusion ?
