Hi,

I have requirement to receive multicast DIS messages from any node without
resetting the trickle timer.

As standard indicates that if any node will receive the multicast DIS
message , it will be considered as inconsistency with respect to trickle
timer of recipient(RFC 6550 ,Sec 8.3).
It also indicates this behavior can be controlled by DIS flag.

But after checking the DIS flag option , it is mentioned that it is unused
filed (Sec 6.2.1).
"Flags: 8-bit unused field reserved for flags.  The field MUST be
         initialized to zero by the sender and MUST be ignored by the
         receiver."

Please suggest if there is any way to stop the reset of trickle timer in
case of reception of multicast DIS message.
