Hi,

Thanks for the clarification.

We are just considering here one RPLInstance.

Working with different RPLInstances, involves deeply analysis, which we
could do in the future. But, actually I dont know if it is possible/useful
to send a message from one RPL Instance to another one , since for
example a RPL
node may belong to multiple RPL Instances, and it may act as a router in
some and as a leaf in others[1], for this reason it does not make sense to
me sending packet from one RPLInstance to other RPLInstance. Besides the
control messages has one field for RPLInstanceID, it does not have
RPLInstanceID origen or RPLInstanceID dst.

What do you think?

Thank you,

Ines

[1] RFC6550. Section 5. RFC 6550 describes only how a single instance
behaves
