Hi,

I saw that in the RFC 6550 the DTSN value is used to trigger DAO messages from sub-DODAG. My question is, when would it be useful to increment this value?
In the RFC it says: 'A RPL implementation MAY allow for configuring a set of rules specifying the triggers for DTSN increment (manual or event-based).' Which events could be used to trigger the DTSN incrementation?
Thank you very much.

Regards,

Alejandro
