Non-Querier behaviour on receiving grp specific or grp-and-src specific queries

Hi,

     I have an issue for which the RFC 3376 does not suggest anything.
Lets say in a Lan there are two igmpv3 routers and one igmpv3 host
present. Lets say Q1 is querier and Q2 is non-querier. Now Host1 sends
include s1 for grp G1. Both Q1 and Q2 will have an entry in their
respective database. Now Host1 sends a report block s1 for grp G1. Q1 on
receipt of this block report will start LMQT timer, set the source timer
of s1 to LMQT and start sending group and source specific queries for
G1/s1. After LMQT expires Q1 will delete the entry of G1/s1 from its
database. Now what will be the non-querier's behaviour. Will it also
start LMQT, in that case Querier's LMQT and non-querier's LMQT (which is
LMQC*LMQI) may differ based on different LMQC values. Non-querier comes
to know about the querier's LMQI from the Max Response Code in the
specific query pkt but what about querier's LMQC, non-querier has no way
to know about the querier's LMQI.

 

Can anyone throw some light on this?

 

Thanks

Suvendu.
