Hi, The querier should send version 1 queries,
as mentioned in the section 7.3.2 of RFC 3376. “IGMPv3 routers may be placed on a network where there are hosts that have not yet been upgraded to IGMPv3. In order to be compatible with older version hosts, IGMPv3 routers MUST operate in version 1 and version 2 compatibility modes. IGMPv3 routers keep a compatibility mode per group record. A group's compatibility mode is determined from the Group Compatibility Mode variable which can be in one of three states: IGMPv1, IGMPv2 or IGMPv3. This variable is kept per group record and is dependent on the version of Membership Reports heard for that group as well as the Older Version Host Present timer for the group.

magma-bounces at ietf.org [mailto:magma-bounces at ietf.org] On Behalf Of Suvendu Mozumdar Hi I have this following doubt for
which RFC 3376 has no clear directive. In a LAN there is a v3 querier and three
hosts each of version 1, 2 and 3 respectively. What should be the version of
the general queries sent by the querier, will it send v1 queries, v2 queries or
v3 queries?? Logically thinking it should send queries with the lowest version
present in the LAN. Please advise. Regards, Suvendu. Conexant E-mail Firewall (Conexant.Com) made the following annotations |
