Thanks Rabi for the review. 1. The 'I' bit was introduced recently so that a node not understanding the option ignores the whole message. This could potentially lead to a node not joining as a 6LR or a 6LN. The J flag decides only for node joining as 6LR. As an example, the I bit can be used by root to ensure that only the nodes understanding a given option join (as 6LN/6LR) that instance. There are several other possibilities even for non-root nodes. 2. Will fix the typo.
