Hi All, I was re-reading RFC 3376 for handling compatibility for lower version of querier. In section 7.3.1, it is mentioned that a querier configured to run in V3 mode should lower its version when it sees a lower version query on the same network. From that time onwards, a router should send the lower version queries. Now the question is, when this router should revert back to its configured higher version? The text in section 7.3.1 or elsewhere does not talk about this. Should a timer 'lower_version_querier' be started and updated as and when lower version queries are removed? Please note this is not same as other-querier-present timer. Can someone, who has implemented IGMPv3, let me know how this particular case has been handled in their implementation?
