Identification

A DODAG is uniquely identified by it's Instance ID and DODAG ID, the Instance ID is a 8 bits integer and the DODAG ID is an IPv6 address

• Instance ID : Instance ID of the DODAG
• Manual DODAG ID : Use 6LBR WSN address as DODAG ID or a manual ID
• DODAG ID : Address to be used as DODAG ID if manual DODAG ID is enabled.
• Global DODAG ID : If 6LBR WSN address is used, select between the Global address or the link local address.

Configuration

High level configuration parameters for a RPL network.

• Preference : Preference level for this DODAG, can go from 0 (least preferred) to 7 (most preferred).
• DIO interval doubling : The DIO interval doubling defines the maximum delay between two DIO. The interval between two DIO is doubled each time a DIO is sent until the number of doubling reach this value or a RPL repair is triggered.
• Route lifetime : Lifetime of the upstream routes created by RPL (actual lifetime is the value times Route lifetime units)
• Route lifetime unit : Units used to define the lifetime

Advanced parameters

These parameters should not be modified unless in very specific circumstances as they can break interoperability or render the RPL tree unstable.

• DIO redundancy : Value for the DIO suppression mechanism, set to 0 to disable it.
• Min rank increment : Minimum rank in the DODAG
• Max rank increase : Max increase of rank allowed when switching parents.
