Section 6.7.6 says:

Reserved: 7-bit unused field.  The field MUST be initialized to zero
         by the sender and MUST be ignored by the receiver.

It should say:

Reserved: 8-bit unused field.  The field MUST be initialized to zero
         by the sender and MUST be ignored by the receiver.

Notes:

The error is clear, but it should not affect implementations.

Figure 24 clearly shows that the Reserved field of DODAG Configuration options is 8 bits long.
