Hi All,
I have a Query on Building and Sending Group and Source
Specific Queries according to
draft-ietf-idmr-igmp-v3-07.txt Sec:6.6.3.2 P.n:35

The calculation of the contents of Query says that :
two separate query messages are sent for the group ---

one with "Suppress Router-Side Processing" bit set and contains
all the sources with retransmission state and timers greater than LMQI.

and another one has the Suppress Router-Side Processing" bit clear
and contains all the sources with retransmission state and timers lower
or equal to LMQI .

Why is that we require to send two such queries instead of only the second
one ?
How do we compare the timers , is that the remaining time we have to compare
?

Thanks in advance
Vinod
