The simplest option would be for the router to decide before hand which of its

The receiving router could check if it belongs to the RPL domain listed in the

The IESG-approved draft refers to the RPL instance as the scope where the
routing header can be used. How would this routing header be used for general
source routing (across RPL instances) in an LLN? How would a node use this
routing header if it wants to travel along a source route d
