Hey Adam,
I am currently adopting RPL to our new network stack and while doing so,
I also added sane functionalities which were plainly missing in the old
implementation.
This also includes sending a DIS when initializing RPL for the first time.
However, I am just now realizing that such a DIS can get lost in our
typical LLN case - it may make sense to send a DIS periodically until a
DIO is received?
Does anyone has an opinion on this?
Forcing a DIS from userspace sounds like a good feature. It may help in
testing/debuging the dodag tree interactively.
I also thought about reseting the trickle timer from userspace to
enforce DIOs.
Cheers,
Cenk

As you said: it depends quite a bit on the network and the
parameters. Since
nodes on the current RPL implementation won't send proactively DIS
messages
and the interval of sending DIOs increases, it will usually take
just a couple
of seconds if you try to join the network right after bootup, but
can take
more than one minute in a later phase.
Cheers,
Oleg
